Procurement Notes

Verify current availability as the item is listed under Factory Special Order status. Confirm RoHS compatibility details directly with the manufacturer or authorized distributor before procurement. Ensure the ordering suffix matches required specifications. Request official datasheets for precise electrical parameters. Validate lead times and pricing through direct quotes from approved supply chain partners.

Selection Notes

Select this component when a fixed center frequency of 947.5 MHz is required for bandpass filtering. Verify that the operating environment supports ceramic filter technology. Ensure system impedance matching aligns with standard RF interface requirements. Consult official documentation for insertion loss and rejection characteristics to confirm suitability for specific signal integrity needs.

Part Context

Tusonix specializes in electromagnetic interference and radio frequency interference filtering solutions. The CER0239A falls under their ceramic filter subcategory. This part is protected by multiple U.S. and foreign patents, including US 4,692,726 and US 4,800,348. It serves as a specialized passive component for high-frequency signal processing applications.

Replacement Considerations

The CER0233A is a documented substitute part number from the same manufacturer. Both parts share the same center frequency of 947.5 MHz. Verify mechanical footprint and electrical tolerances before substitution. Consult official cross-reference data to ensure functional equivalence in existing designs.
