Crystals Procurement Notes

Verify the specific suffix configuration against official TXC documentation to ensure compatibility with required load capacitance and temperature ranges. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint design. Check for RoHS compliance status and lead-free soldering requirements relevant to your manufacturing standards before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 13.56 MHz frequency is mandatory for RFID or NFC applications. Consider the ±10 ppm tolerance if strict frequency accuracy is needed compared to looser specifications. Evaluate the 18 pF load capacitance requirement against your oscillator circuit design to ensure proper resonance. Assess the -20°C to +70°C operating range against your environmental conditions.
