CER0235B

Overview

The CER0235B is a high-frequency ceramic band-pass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for robust signal conditioning, this component operates at a center frequency of 942.5 MHz with a bandwidth of 35 MHz, covering the range from 925 to 960 MHz. It utilizes a monoblock package construction and measures 0.256 inches (6.50 mm) in maximum height. The filter is characterized by low ripple, high rejection, and low insertion loss, making it suitable for demanding RF applications requiring precise frequency selection.

Feature Summary

• High-frequency band-pass filtering capability centered at 942.5 MHz
• Monoblock construction for structural integrity and compact integration
• Optimized for low insertion loss and minimal signal ripple
• Provides high out-of-band signal rejection

Applications

• High-frequency RF signal conditioning systems
• Wireless communication infrastructure operating near 942.5 MHz
• Precision radio frequency front-end modules
• Industrial equipment requiring stable band-pass filtering

Procurement Notes

Verify RoHS compliance status as documentation indicates no specific RoHS information is currently available. Confirm that the monoblock package dimensions align with your PCB layout constraints, specifically noting the maximum height of 6.50 mm. Ensure electrostatic discharge handling procedures are followed during installation, as components are hermetically sealed. Cross-reference the manufacturer part number CER0235B with your bill of materials to ensure exact functional equivalence.

Selection Notes

Select this component when a fixed center frequency of 942.5 MHz with a 35 MHz bandwidth is required. The monoblock form factor is ideal for space-constrained designs needing robust mechanical stability. Consider this filter for applications prioritizing low loss and high rejection over tunability. Verify that the operating environment does not exceed the thermal limits specified in the official datasheet.
