CER0358B

Overview

The CER0358B is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within the frequency range of 1182 MHz to 1272 MHz, with a center frequency typically specified at 1227 MHz. The component utilizes a monoblock construction housed in a surface-mount package measuring 10.00 mm x 9.20 mm x 4.00 mm. Designed for SMD/SMT termination, it features a two-pad configuration suitable for automated assembly processes.

Feature Summary

• Monoblock ceramic construction for stable RF performance
• Surface-mount design optimized for high-volume production
• Bandpass filtering capability in the UHF spectrum

Applications

• RF communication systems requiring signal isolation
• Wireless infrastructure equipment
• UHF transceiver modules

Procurement Notes

Verify the specific datasheet version from CTS/Tusonix to confirm exact insertion loss and rejection specifications, as these values are critical for circuit design. Ensure the ordering suffix matches the required tape and reel packaging quantity if applicable. Confirm RoHS compliance status through official manufacturer documentation prior to procurement.

Selection Notes

Select this component when a compact, high-reliability ceramic filter is needed for frequencies around 1.2 GHz. The monoblock package offers mechanical stability compared to discrete resonator assemblies. Evaluate board space constraints against the 10mm x 9.2mm footprint requirements before integration into the final assembly design.

Part Context

This part belongs to the CER series of ceramic filters produced by Tusonix. These components are engineered for applications demanding precise frequency selection with minimal size. The series provides alternatives to bulkier LC filters or SAW devices in specific UHF bands where ceramic technology offers superior power handling and thermal stability.

Replacement Considerations

Consult official CTS substitution guides for direct equivalents. Verify that any alternative maintains the same 10x9mm footprint and 1227 MHz center frequency. Cross-reference pinout compatibility and electrical tolerances to ensure seamless integration without redesigning the PCB layout.
