CER0234A

Overview

The CER0234A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within the 880 MHz to 915 MHz frequency range with a center frequency of 897.5 MHz. The component utilizes a monoblock package with two PC pads for surface mount installation. Its physical dimensions are 33.8 mm in length, 12.6 mm in width, and 6.5 mm in maximum height. The device is RoHS compliant and classified under ECCN EAR99.

Feature Summary

• Low insertion loss characteristics
• High signal rejection capabilities
• Minimal passband ripple

Applications

• Industrial, Scientific, and Medical (ISM) radio equipment
• Wireless sensor networks operating in sub-GHz bands
• Short-range communication devices requiring stable filtering

Procurement Notes

Verify the specific datasheet version from Tusonix or authorized distributors to confirm exact electrical tolerances and mechanical drawings. Ensure compatibility with surface mount assembly processes given the monoblock form factor. Check for updated RoHS compliance status against current regional regulations before finalizing procurement orders.

Selection Notes

Select this component when a robust ceramic solution is required for frequencies between 880 MHz and 915 MHz. The large monoblock package offers mechanical stability compared to smaller SMD alternatives. Consider thermal management requirements as ceramic filters can dissipate power differently than active components.

Part Context

This part belongs to the Tusonix CER series of ceramic filters, designed for high-performance RF applications. The series typically emphasizes reliability and consistent performance across varying environmental conditions. It serves as a passive filtering solution for systems needing precise frequency selection without active circuitry.

Replacement Considerations

No direct public substitute part numbers are confirmed for this specific model. Evaluate alternative ceramic filters from Tusonix or other manufacturers only if they match the 880-915 MHz bandwidth and monoblock mounting constraints exactly.
