PRQC20.00CR1010V00L

Resonators Overview

The KYOCERA AVX PRQC20.00CR1010V00L is a surface-mount ceramic resonator designed for microcontroller clock applications. It operates at a nominal frequency of 20 MHz with a built-in 10 pF load capacitor, eliminating the need for external matching components. The device features a frequency tolerance of ±0.1% and stability of ±0.5%. It supports a DC voltage rating of 100 V and a maximum input signal of 15 V peak-to-peak. The component functions within an operating temperature range of 0°C to +70°C and utilizes a non-standard 3-SMD package.

Resonators Feature Summary

• Integrates a 10 pF load capacitor to simplify circuit design and reduce PCB footprint
• Provides stable oscillation for general-purpose microcontrollers without external capacitors
• RoHS compliant construction suitable for consumer electronics manufacturing

Resonators Applications

• Microcontroller unit (MCU) clock sources in consumer IoT devices
• General-purpose digital logic timing circuits
• Small form-factor electronic products requiring space-efficient clock solutions

Resonators Procurement Notes

Verify that the application environment remains within the specified 0°C to +70°C operating range, as this component is not rated for industrial or automotive wide-temperature conditions. Ensure the standard test circuit provided by the manufacturer is used during validation to confirm frequency accuracy, as custom test setups may yield inaccurate deviation readings. Confirm RoHS compliance requirements align with final product regulations.

Resonators Selection Notes

Select this component when minimizing bill-of-materials complexity and PCB area is critical for MCU clock generation. It serves as a cost-effective alternative to quartz crystals by removing the requirement for two external load capacitors. Do not utilize this part for high-frequency precision applications or environments exceeding 70°C, where quartz crystal oscillators offer superior thermal stability and wider operational ranges.

Resonators Part Context

This part belongs to the PRQC series of surface-mount ceramic resonators manufactured by KYOCERA AVX. The series is engineered specifically for low-cost, space-constrained digital applications. Unlike discrete crystal assemblies, these resonators combine the piezoelectric element and internal capacitance into a single SMD package, streamlining the assembly process for mass-produced consumer electronics.

Resonators Replacement Considerations

Direct substitutes include other PRQC series variants with different frequencies, such as PRQC16.00CR1010V00L or PRQC10.00CR1010V00L, provided the system clock speed can be adjusted accordingly. Generic ceramic resonators from other manufacturers may replace this part only if they match the 20 MHz frequency, 10 pF internal capacitance, and physical footprint constraints.
