Crystals Procurement Notes

Verify the specific suffix 'JC' against official Meritek documentation to confirm the exact temperature range (-20°C to +70°C) and tolerance (±50 ppm). Ensure the ordering code matches the required load capacitance of 32 pF. Confirm RoHS compliance status through the manufacturer's current datasheet rather than third-party listings.

Crystals Selection Notes

Select this component when a 20 MHz fundamental mode crystal is required with moderate frequency tolerance. The 32 pF load capacitance must match the oscillator circuit design. Consider the -20°C to +70°C operating range for environmental constraints. The 4-pin SMD package facilitates automated assembly processes.

Crystals Part Context

Part of the Meritek MX3 series of ceramic SMD crystals. The series offers various frequency options and package sizes. This specific model represents a standard 20 MHz variant optimized for general-purpose timing applications in consumer and industrial electronics.

Crystals Replacement Considerations

Direct substitutes must match the 3225 (6.0x3.5mm) footprint, 20 MHz frequency, 32 pF load capacitance, and ±50 ppm tolerance. Verify equivalent thermal characteristics and drive level specifications before substitution.
