CER0236A

Overview

The CER0236A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for RF applications, it operates within the 824 to 849 MHz frequency range with a center frequency of 836.5 MHz. The component features a bandwidth of 25 MHz and an insertion loss of less than 3.5 dB. It utilizes a surface-mount package configuration suitable for automated assembly processes.

Feature Summary

• Provides electromagnetic interference suppression through dedicated bandpass filtering characteristics
• Utilizes ceramic construction for stable RF signal transmission in compact form factors
• Engineered for surface-mount installation to support modern PCB assembly techniques

Applications

• Wireless communication systems requiring specific frequency band selection
• RF front-end modules needing interference rejection
• Electronic devices utilizing the 800 MHz spectrum range

Procurement Notes

Verify the manufacturer designation as Tusonix, a subsidiary of CTS Electronic Components, against official datasheets. Confirm the part number CER0236A matches the specified 836.5 MHz center frequency and 25 MHz bandwidth parameters. Ensure compliance with RoHS standards if required by your supply chain specifications before finalizing orders.

Selection Notes

Select this component when a fixed 25 MHz bandwidth at 836.5 MHz is required. Compare insertion loss specifications against system sensitivity requirements. Evaluate surface-mount footprint compatibility with existing PCB layouts. Consider thermal management needs relative to the ceramic package type and intended operating environment.

Part Context

This component belongs to the passive components category, specifically under ceramic filters. Tusonix specializes in EMI/RFI filtering solutions. The CER series represents standard fixed-frequency filters designed for general-purpose RF applications where discrete LC networks might be too large or inconsistent.
