Crystals Procurement Notes

Verify the specific suffix codes against the manufacturer datasheet to ensure correct load capacitance and tolerance specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to integration. Ensure ordering quantities align with standard reel packaging constraints provided by authorized distributors. Cross-reference part numbers to distinguish between engineering samples and mass production versions.

Crystals Selection Notes

Select this component when a 37.4 MHz frequency point is required with ±10 ppm accuracy. The 10 pF load capacitance must match the oscillator circuit design parameters. Consider the -20°C to +70°C operating range suitability for the target environment. The 50 Ohm ESR limit ensures compatibility with standard MCU internal oscillator circuits without additional driving components.

Crystals Part Context

This model belongs to the TXC 7M series, which specializes in 3.2x2.5mm seam-sealed quartz crystals. The series offers improved reliability compared to plastic packages, making it suitable for harsh environments. It serves as a passive frequency control element in electronic circuits requiring precise timing references.

Crystals Replacement Considerations

Direct substitutes include other 37.4 MHz crystals with identical 10 pF load capacitance and ±10 ppm tolerance. Verify package dimensions and pin configuration compatibility before substitution. Alternative models from the same manufacturer may offer different temperature ranges or aging rates.
