Resonators Procurement Notes

Verify the specific suffix GH5C000 against official Murata documentation to confirm the exact electrical parameters, particularly the 39 pF load capacitance and 60 Ohm ESR. Ensure the selected variant matches the required 4.194 MHz frequency and ±0.07% tolerance for your circuit design. Confirm RoHS compliance status through the manufacturer's latest datasheet before finalizing procurement.

Resonators Selection Notes

Select this component when a stable clock source is required for microcontrollers or logic circuits in automotive electronics. The built-in capacitor simplifies PCB layout by reducing component count. Verify that the 6 VDC maximum operating voltage aligns with the system power supply. Consider the 60 Ohm ESR value for oscillator circuit compatibility and startup reliability.
