• RoHS compliant manufacturing process

Crystals Applications

• General purpose clock signal generation
• Microcontroller oscillator circuits
• Communication interface timing

Crystals Procurement Notes

Verify the specific ESR value of 100 Ohms against circuit requirements, as this differs from other variants in the CSM1 series which may feature lower resistance values. Confirm the HC-49S footprint compatibility during layout design. Ensure the operating temperature range of -10°C to +60°C meets environmental specifications. Cross-reference the part number suffixes to confirm tape and reel availability if required for high-volume production.

Crystals Selection Notes

Select this component when a 40 MHz fundamental frequency is required with moderate stability needs. The 100 Ohm ESR suits oscillator circuits designed for higher impedance loads compared to low-resistance alternatives. Consider the HC-49S package size constraints relative to PCB real estate. Evaluate thermal performance within the specified -10°C to +60°C range before deployment in harsh environments.

Crystals Part Context

This part belongs to the CSM1 series of surface mount crystals from Cardinal Components Inc. The series offers various frequency and resistance combinations packaged in the HC-49S form factor. Variants differ primarily in ESR values and frequency tolerances while maintaining similar physical dimensions and mounting characteristics for interchangeable design applications.

Crystals Replacement Considerations

HC-49S package crystals from other manufacturers offering 40 MHz frequency and 100 Ohm ESR can serve as functional substitutes. Verify that alternative parts match the 18 pF load capacitance and ±30 ppm tolerance to ensure circuit compatibility without redesign.
