Procurement Notes

Verify the specific ordering suffix and packaging configuration when sourcing, as availability may vary between tape-and-reel and cut-tape formats. Confirm that the required frequency tolerance of ±20ppm aligns with the system design requirements. Ensure the operating temperature range of -40°C to +85°C covers the intended application environment. Cross-reference the manufacturer part number STDCRG2-13.56M with official NDK documentation to confirm current production status and lead times before finalizing procurement plans.

Selection Notes

Select this component for applications requiring a standard 13.56 MHz reference frequency in space-constrained designs. The 80 Ohm ESR and 8pF load capacitance must match the oscillator circuit's design parameters. Consider the ±20ppm tolerance if higher precision is not critical. The 4-SMD package facilitates automated assembly. Verify compatibility with the target microcontroller or RF front-end input impedance.

Part Context

This component belongs to the STD-CRG-2 series of surface-mount crystals from NDK. It utilizes artificial quartz technology to ensure high quality and reliability. The series is designed for general-purpose timing applications where moderate stability and compact size are prioritized. The STDCRG2-13.56M specifically targets the 13.56 MHz ISM band commonly used in contactless communication technologies.
