Resonators Procurement Notes

Verify the specific suffix 'C' against the official Murata datasheet to confirm the exact frequency tolerance and temperature grade, as ordering suffixes define critical electrical parameters. Ensure the procurement channel provides traceability documentation required for AEC-Q200 certified components. Cross-reference the manufacturer part number with authorized distributor listings to avoid counterfeit parts. Confirm RoHS compliance status matches current regulatory requirements for the target market.

Resonators Selection Notes

Select this component when a stable 20 MHz reference is required for microcontrollers or logic circuits without external tuning. The built-in capacitor reduces board space and component count compared to discrete crystal solutions. Consider the ±0.15% stability requirement against system timing budgets. The wide temperature range makes it suitable for under-hood automotive environments where standard commercial-grade resonators may fail. Evaluate footprint compatibility with existing PCB layouts.
