Resonators Procurement Notes

Verify that the specific part number matches the required 4.096 MHz frequency and 15 pF load capacitance specifications. Confirm compatibility with the target oscillator circuit topology, as the integrated capacitor value dictates the necessary external tuning conditions. Ensure the selected variant meets the thermal requirements of the intended operational environment within the specified temperature range.

Resonators Selection Notes

Select this component when a precise 4.096 MHz clock source is required with minimal external circuitry complexity. The integrated capacitor simplifies layout and reduces bill of materials count compared to discrete crystal solutions. Consider the ±0.5% tolerance and ±0.2% stability metrics against system timing accuracy requirements. Evaluate the physical dimensions and surface-mount mounting style for PCB integration feasibility.

Resonators Part Context

This component belongs to the CSTCR_G series of small-cap chip type ceramic resonators. It is part of the broader CERALOCK product line, which leverages piezoelectric ceramic multi-crystal mechanical resonance properties. The series provides stable clock signals for ICs and LSIs without requiring adjustment, offering a compact alternative to traditional quartz crystals in consumer and industrial electronics.

Resonators Replacement Considerations

Direct substitutes include other Murata ceramic resonators with identical 4.096 MHz frequency, 15 pF load capacitance, and compatible physical footprint. Verify that any replacement maintains the same frequency tolerance, stability rating, and operating temperature range to ensure circuit performance consistency.
