XDCAH73M350QHA03P0

Overview

The XDCAH73M350QHA03P0 is a monolithic crystal filter manufactured by Murata Electronics, designed for signal conditioning applications at a center frequency of 73.35 MHz. It features a 450 Ohms impedance and a bandwidth of 6 kHz with 1 dB ripple. The component utilizes a surface mount package measuring 7.00 mm x 5.00 mm x 1.25 mm (0.276" L x 0.197" W x 0.049" H). This device offers excellent selectivity with minimal insertion loss in a compact form factor.

Feature Summary

• High reliability construction based on original thin wafer design technology
• Excellent selectivity with minimal insertion loss
• Compact surface mount package suitable for space-constrained designs

Applications

• Signal conditioning circuits
• RF front-end filtering
• Communication equipment requiring 73.35 MHz band selection

Procurement Notes

This component is classified as an End-of-Life (EOL) product. Buyers must verify current availability through authorized distributors, as stock is limited. Review the official discontinuance notification for transition timelines. Ensure compatibility with existing PCB footprints before procurement planning due to the obsolete status.

Selection Notes

Select this part only if the specific 73.35 MHz center frequency and 6 kHz bandwidth match the system requirements. Verify that the 450 Ohms impedance aligns with the circuit interface. Consider the 7x5mm package dimensions for layout constraints. Due to the EOL status, alternative components or redesign may be necessary for new production runs.

Part Context

Murata's monolithic crystal filters utilize proprietary thin wafer technology to achieve high performance in small packages. The XDCAH series is engineered for reliable signal processing in various electronic devices. This specific model represents a legacy solution for narrowband filtering applications at VHF frequencies.

Replacement Considerations

As an EOL product, direct substitutes are not officially confirmed in public documentation. Engineers should consult Murata for recommended alternatives or perform a full redesign using currently active monolithic crystal filters with matching electrical specifications.
