CS12403-55.2M

Overview

The CS12403-55.2M is a surface-mount quartz crystal resonator manufactured by NDK (NIHON DEMPA KOGYO CO., LTD). It operates at a fundamental frequency of 55.2 MHz with a frequency tolerance and stability of ±10 ppm. The component features an 8 pF load capacitance and an equivalent series resistance (ESR) of 50 Ohms. It utilizes a 4-SMD, no-lead package with dimensions of 3.20 mm x 2.50 mm and a maximum height of 0.60 mm.

Feature Summary

• Fundamental mode operation for precise frequency generation
• Compact 4-SMD no-lead surface mount design
• High frequency stability of ±10 ppm

Applications

• Clock signal generation in microcontroller circuits
• Communication module timing references
• Digital logic circuit synchronization

Procurement Notes

Verify the specific datasheet version, identified as STD-CSR-1 or similar, to confirm exact electrical parameters and mechanical drawings before integration. Ensure compatibility with the target PCB footprint and reflow soldering profile. Confirm RoHS compliance status matches project requirements. Cross-reference manufacturer part numbers against distributor listings to avoid ordering errors due to suffix variations.

Selection Notes

Select this component when a 55.2 MHz fundamental frequency is required with tight ±10 ppm stability. The 8 pF load capacitance must match the oscillator circuit design. The 4-SMD 3.2x2.5mm package suits space-constrained layouts. Verify ESR limits against driver strength requirements. Consider operating temperature range specifications for environmental suitability.

Part Context

This part belongs to NDK's standard SMD crystal lineup, designed for general-purpose timing applications. It shares the NX3225SA series form factor, ensuring mechanical interchangeability within that family. The component supports mass production through reel packaging options. It serves as a critical passive element for establishing stable clock frequencies in embedded systems.

Replacement Considerations

Direct substitutes include other 55.2 MHz crystals with identical 8 pF load capacitance, ±10 ppm tolerance, and 4-SMD 3.2x2.5mm footprint. Verify ESR values and temperature coefficients match original specifications. Check for pinout compatibility if alternative manufacturers offer different lead configurations.
