CER0002A

Overview

The CER0002A is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates at a center frequency of 881.5 MHz and supports the 869-894 MHz signal conditioning range. The component utilizes a 0402 (1106 metric) surface-mount package. It is designed for RF applications requiring precise frequency selection within this specific bandwidth.

Feature Summary

• Provides bandpass filtering characteristics centered at 881.5 MHz
• Supports signal conditioning in the 869-894 MHz frequency range
• Utilizes compact 0402 surface-mount packaging for space-constrained designs

Applications

• RF signal conditioning
• Wireless communication systems operating in the 869-894 MHz band

Procurement Notes

Verify manufacturer authenticity as Tusonix is a subsidiary of CTS. Confirm RoHS compliance status as documentation indicates no explicit RoHS information. Ensure the 0402 package type matches PCB footprint requirements. Validate the 881.5 MHz center frequency against system specifications to ensure compatibility with the 869-894 MHz operational range.

Selection Notes

Select this component when a fixed-frequency ceramic filter is required for the 869-894 MHz band. The 0402 package size is suitable for high-density circuit boards. Consider the specific center frequency of 881.5 MHz to ensure it aligns with the target application's channel requirements. Verify that the passive component line meets the environmental and electrical constraints of the design.

Part Context

This part belongs to the Ceramic Filters product line from Tusonix/CTS. It is categorized under Passive Components. The component is distinct from variable capacitors or other signal conditioning devices listed in broader searches, specifically serving as a fixed-bandpass filter for RF applications.

Replacement Considerations

Cross-reference with other CER series filters from Tusonix or CTS if exact availability is an issue. Verify that any substitute maintains the 881.5 MHz center frequency and 0402 package dimensions to ensure mechanical and electrical compatibility.
