It operates at a nominal frequency of 25 MHz with a tolerance of ±0.5% and stability of ±0.3%. The component features an integrated load capacitance of 10 pF and a resonant impedance of 40 Ohms. It supports a standard operating temperature range of -25°C to +85°C. The device utilizes a compact 3-SMD non-standard package measuring 3.7 mm in length, 3.1 mm in width, and 1.0 mm in height.

Feature Summary

• Integrates matched internal capacitors to eliminate external component requirements
• Provides simplified PCB layout through single-component replacement of crystal assemblies
• Offers stable frequency performance within specified industrial temperature ranges

Applications

• Microcontroller system clock generation
• Consumer electronics timing circuits
• Industrial control module oscillators

Procurement Notes

Verify that the specific order suffix matches the required capacitance and tolerance specifications. Confirm RoHS compliance status for environmental regulations. Ensure the selected packaging format aligns with automated assembly equipment capabilities. Cross-reference the manufacturer part number against distributor databases to confirm current availability and lead times before finalizing procurement plans.

Selection Notes

Select this component when space constraints prevent the use of discrete crystals and load capacitors. Verify that the 10 pF internal capacitance matches the target microcontroller's load requirements. Consider the 40 Ohm impedance for driver circuit compatibility. Evaluate the -25°C to +85°C range against the operational environment to ensure reliability under thermal stress conditions.

Part Context

This part belongs to the Abracon AWSCR-CV family of built-in capacitor ceramic resonators. These components are engineered to replace traditional quartz crystal oscillator setups by integrating necessary matching capacitors directly into the package. The series targets cost-sensitive and space-constrained designs requiring moderate frequency accuracy without the complexity of external tuning networks.

Replacement Considerations

Direct replacements include other Abracon AWSCR-CV series variants with identical 25 MHz frequency and 10 pF capacitance but different tolerances or packages. Verify pinout compatibility and physical dimensions when substituting with generic ceramic resonators. Ensure equivalent impedance characteristics to maintain oscillator startup reliability.
