Resonators Procurement Notes

Verify the specific suffix and part number against official Murata documentation to ensure correct specifications. Confirm that the required load capacitance matches the system design requirements. Check RoHS compliance status if restricted substances are a constraint. Ensure the operating temperature range meets the environmental conditions of the target application.

Resonators Selection Notes

Select this component when a compact, cost-effective timing solution is required for microcontroller or logic circuits. The built-in capacitor simplifies PCB layout by reducing component count. Consider the 4.5 MHz frequency and 50 Ohm impedance limits relative to the oscillator circuit capabilities. Evaluate the physical dimensions against available board space constraints.

Resonators Part Context

This part belongs to the CSTCR_G series of small-cap chip type ceramic resonators. These devices are designed as direct replacements for crystal oscillators in applications where high precision is not critical. The CERALOCK branding indicates Murata's proprietary technology for integrating capacitors within the ceramic body.

Resonators Replacement Considerations

Direct substitutes must match the 4.5 MHz frequency, 15 pF load capacitance, and 50 Ohm impedance. Verify package dimensions (4.5x2x1.15 mm) and terminal configuration. Cross-reference with other manufacturers' ceramic resonators offering similar integrated capacitance values.
