Crystals Procurement Notes

Verify the specific ordering suffix against the manufacturer datasheet to ensure correct frequency tolerance and packaging configuration. Confirm that the selected variant matches the required load capacitance and ESR values for the target oscillator circuit design. Check current availability status as lead times may vary. Ensure compliance with project-specific environmental regulations such as RoHS3 requirements before finalizing procurement orders.

Crystals Selection Notes

Select this component when a 13.56 MHz frequency is required for RFID or NFC applications. Ensure the circuit design accommodates the 18pF load capacitance and 60 Ohm ESR specifications. Verify that the operating temperature range of -20°C to 70°C meets the environmental conditions of the end application. Compare physical dimensions against available PCB footprint constraints to ensure compatibility with the 5.00mm x 3.20mm package size.

Crystals Part Context

This part belongs to the 435 series of surface mount crystals from CTS-Frequency Controls. These components are characterized by their glass seal technology, which provides hermetic sealing for improved reliability compared to standard epoxy-sealed alternatives. The series offers various frequency options and tolerances tailored for digital clock generation and RF carrier frequencies in consumer electronics and industrial equipment.

Crystals Replacement Considerations

Direct substitutes include other 13.56 MHz SMD crystals with matching 18pF load capacitance and similar ESR values.
