The component features built-in capacitors with a capacitance value of 30 pF and a resonant impedance of 40 Ohms. It supports a load capacitance of 30 pF and exhibits a frequency-temperature coefficient of -25 ppm/°C². The device functions within an operating temperature range of -25°C to +85°C.

Feature Summary

• Integrates built-in capacitors to simplify circuit design and reduce component count
• Provides stable frequency generation with high tolerance accuracy for timing applications
• Utilizes a three-pin through-hole package for reliable mechanical attachment

Applications

• Microcontroller clock sources
• Simple oscillator circuits
• Consumer electronics timing references

Procurement Notes

Verify the specific suffix requirements against the official Abracon datasheet to ensure compatibility with your board layout and thermal profile. Confirm that the through-hole pin spacing matches your PCB footprint dimensions. Check for RoHS compliance status if required by your manufacturing standards. Ensure the 30 pF internal capacitance aligns with your circuit design requirements without external loading components.

Selection Notes

Choose this component when a cost-effective, simple timing solution is needed for microcontrollers or logic circuits. It is suitable for applications where moderate frequency stability is acceptable and space constraints allow for through-hole mounting. Consider the 40 Ohm impedance and 30 pF capacitance values when designing the oscillator circuit to ensure proper startup and operation.

Part Context

This part belongs to Abracon's AWCR series of ceramic resonators, which are passive timing components used as alternatives to quartz crystals in less demanding applications. The series offers various frequencies and packages, providing designers with options for different mounting styles and performance levels. Ceramic resonators generally offer lower Q-factors than crystals but provide adequate stability for many digital logic applications.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 30 pF capacitance, and through-hole 3-pin package. Verify impedance and temperature characteristics. Cross-reference with other manufacturers' ceramic resonator specifications to ensure functional equivalence in your specific circuit design.
