• Provides stable clock signals without requiring manual frequency adjustment.
• Utilizes piezoelectric ceramic multi-crystal technology for mechanical resonance.
• Offers a compact surface-mount package suitable for space-constrained applications.

Resonators Applications

• Clock reference sources for microcontrollers and LSI systems
• Automotive electronic control units
• Communication equipment timing circuits
• Personal computer peripheral interfaces

Resonators Procurement Notes

Verify the specific suffix G53 against the official Murata datasheet to confirm the exact frequency tolerance and impedance characteristics required for the target application. Ensure that the operating temperature range of -20°C to +80°C aligns with the environmental conditions of the end product. Confirm RoHS3 compliance status if restricted substance regulations apply to the manufacturing process.

Resonators Selection Notes

Select this component when a cost-effective, low-profile clock source is needed for digital logic circuits. The 15 pF internal capacitance must match the oscillator circuit requirements of the host IC. Consider the 50 Ohm impedance limit to ensure proper oscillation startup. This type is suitable where crystal precision is not critical but size and assembly simplicity are priorities.

Resonators Part Context

This part belongs to the CSTCC series, which represents small-cap chip type ceramic resonators. It is part of the broader CERALOCK family known for replacing traditional crystals in consumer electronics. The designation indicates a 3 MHz frequency variant with specific tolerance grades defined by the manufacturer's coding system.

Resonators Replacement Considerations

Direct substitutes include other Murata ceramic resonators with identical 3 MHz frequency, 15 pF load capacitance, and similar physical footprint, such as variants within the CSTCR or CSTCC series that share the same pin configuration and electrical parameters.
