AWSCR-8.00CV-T 8.00 MHz Ceramic Resonator with Built-in 22 pF Capacitors for Compact SMT Applications

The AWSCR-8.00CV-T is a compact 8.00 MHz ceramic resonator designed for stable clock generation in a wide range of electronic applications. With built-in 22 pF load capacitors, a small surface-mount package, and reliable operation across a wide temperature range, this device offers an efficient timing solution for designers seeking to simplify circuit layout, reduce external component count, and improve manufacturing efficiency. It is well suited for consumer electronics, microcontroller-based systems, industrial control products, communication modules, and general embedded applications where a cost-effective and space-saving clock source is required.

One of the most practical advantages of the AWSCR-8.00CV-T is its built-in load capacitors. The device integrates 22 pF load capacitors internally, which eliminates the need for external capacitors in many clock circuit designs. This feature helps simplify the schematic and PCB layout, reduces the total number of components on the board, and shortens the design process. For manufacturers and design engineers, fewer external parts mean lower BOM cost, less assembly complexity, and better use of limited PCB space. In compact electronic designs, this integration can provide an important advantage by helping achieve cleaner routing and more efficient board utilization.

The resonator is designed for Surface Mount Technology (SMT) and comes in a compact package size of approximately 3.7 mm × 3.1 mm × 1.0 mm. Its small dimensions make it highly suitable for modern automated assembly lines and densely populated PCBs. Because the device is compatible with standard SMT processes, it supports high-volume production with improved consistency and lower labor requirements. This makes it especially attractive for products where manufacturing efficiency and miniaturization are important. In today's electronics market, many applications require both reliable timing performance and reduced footprint, and this resonator is designed to meet those needs.

Another key feature of the AWSCR-8.00CV-T is its wide operating temperature range of -25°C to +85°C. This allows the device to operate reliably under various environmental conditions, making it suitable for both indoor and moderately demanding industrial or commercial applications. Electronic products may experience temperature variation during normal operation, transportation, storage, or installation, so dependable frequency performance across the rated temperature range is critical. By supporting operation from sub-zero temperatures up to elevated ambient conditions, the resonator can be used in many different environments without compromising functionality.

The device also features low resonant impedance of 30 ohms, which contributes to efficient oscillation and improved signal performance. Low resonant impedance helps ensure more effective energy transfer within the oscillator circuit and reduces signal loss. In practical applications, this can support stable startup behavior and dependable clock generation when used with compatible microcontrollers or logic circuits. Efficient energy transfer is important because the clock source directly affects the timing accuracy and stability of the overall system. A low-impedance resonator can therefore help improve operational reliability in embedded designs.

The frequency stability of ±0.4% over the specified temperature range is another strong benefit of this product. For many timing and control applications, consistent frequency output is essential to maintain proper device operation, communication timing, and control accuracy. The AWSCR-8.00CV-T is designed to provide stable performance across its rated operating conditions, making it suitable for applications where moderate frequency precision is required. While ceramic resonators are generally more cost-effective than quartz crystals, maintaining good frequency stability is still a key requirement, and this device offers a practical balance between performance and cost.

Because of these features, the AWSCR-8.00CV-T is particularly useful in microcontroller clock circuits. Many embedded systems require an external resonator to provide the timing reference for the CPU, peripheral modules, or communication interfaces. With its built-in capacitors and 8.00 MHz nominal frequency, this resonator offers a convenient and compact timing solution for MCU-based designs. It can be used in control boards, home appliances, small instruments, remote controls, consumer products, and other electronics where a dependable clock source is needed but where cost, board space, and ease of assembly are also important considerations.

Compared with solutions that require an external crystal plus separate load capacitors, the AWSCR-8.00CV-T offers a more integrated approach. This integration helps reduce component sourcing complexity and can simplify inventory management for manufacturers. Fewer parts on the board also help reduce pick-and-place operations during production, which can improve throughput and reduce manufacturing errors. For high-volume production environments, these practical benefits can make a meaningful difference in cost control and assembly efficiency.

The resonator's compact SMT structure also supports design trends toward lighter, smaller, and more portable electronics. As products become more miniaturized, every square millimeter of PCB area becomes increasingly valuable. A resonator with integrated capacitors allows engineers to build more compact clock circuits without sacrificing basic timing reliability. This is especially useful in products such as handheld controllers, compact sensor modules, wireless accessories, smart home devices, and low-profile embedded systems.

From a performance perspective, the AWSCR-8.00CV-T offers a dependable solution for applications that do not require the ultra-high precision of a quartz crystal but still need stable and efficient frequency control. Ceramic resonators are often selected because they provide a good balance of cost, size, ease of use, and acceptable timing performance. This makes them highly attractive in mass-market electronic products. The ±0.4% frequency stability of this model supports many general timing applications where system tolerances are compatible with ceramic resonator characteristics.

In addition to simplifying hardware design, the device can also help improve product reliability at the system level. By using an integrated resonator solution with well-matched built-in load capacitors, engineers reduce the chance of capacitor selection errors or layout-related performance problems. This contributes to more consistent oscillation characteristics between prototypes, pilot production, and full-scale manufacturing. In practical terms, it can shorten development time and reduce the need for repeated tuning during validation.

The AWSCR-8.00CV-T is suitable for a broad range of applications, including consumer electronics, microcontroller modules, industrial controls, small appliances, instrumentation, communication products, and embedded controller boards. Its combination of compact size, stable 8.00 MHz operation, integrated capacitors, low impedance, and wide operating temperature range makes it a practical timing component for many standard electronic designs.

Overall, the AWSCR-8.00CV-T provides a well-balanced solution for customers looking for a compact, easy-to-use, and cost-effective ceramic resonator. It reduces external component requirements, saves PCB space, supports automated SMT assembly, and delivers stable clock performance under common operating conditions. For engineers and buyers seeking a reliable resonator for medium-precision timing applications, this device is an excellent choice.
