CSM1Z-A1B2C3-200-3.6864D20

Crystals Overview

The CSM1Z-A1B2C3-200-3.6864D20 is a fundamental quartz crystal oscillator manufactured by Cardinal Components Inc. It operates at a nominal frequency of 3.6864 MHz with a frequency tolerance of ±30 ppm and a load capacitance of 20 pF. The component features a series resistance of 200 Ω and supports a maximum drive level of 1000 µW. Designed for surface mount installation, it utilizes an HC-49S package configuration with dimensions of 11.40 mm length by 4.70 mm width. The unit complies with RoHS standards and functions within an operating temperature range of -10°C to +70°C.

Crystals Feature Summary

• AT cut fundamental quartz construction
• Surface mount HC-49S package design
• RoHS compliant manufacturing

Crystals Applications

• General purpose clock signal generation
• Microcontroller timing circuits
• Digital communication interfaces

Crystals Procurement Notes

Verify the specific package variant against the HC-49S designation when sourcing. Confirm that the 200 Ω series resistance aligns with the target oscillator circuit requirements. Ensure the -10°C to +70°C temperature range meets the operational environment specifications. Cross-reference the 20 pF load capacitance with the host system's design parameters to guarantee frequency accuracy.

Crystals Selection Notes

Select this component when a standard surface mount footprint is required for low-frequency timing applications. The HC-49S form factor offers a balance between stability and board space efficiency. Consider the 30 ppm tolerance for general digital logic rather than high-precision RF applications. Verify compatibility with the intended PCB layout for the two-pin SMD configuration.

Crystals Part Context

This part belongs to the CSM1 series of surface mount crystals from Cardinal Components Inc. The series provides fundamental mode operation in a compact SMD format. The model number encodes specific electrical parameters including frequency, tolerance, and load capacitance. It serves as a direct replacement for through-hole HC-49U crystals where surface mounting is preferred.

Crystals Replacement Considerations

Direct substitutes include other manufacturers' HC-49S packages with identical 3.6864 MHz frequency and 20 pF load capacitance. Ensure equivalent series resistance and temperature range compatibility during substitution.
