CER0109B

Overview

The CER0109B is a ceramic band-pass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. Designed for surface-mount installation in the Monoblock package with two pads, this component operates within a frequency range of 1920 to 1980 MHz. It supports an average power handling capacity of 1 watt and a peak power of 10 watts. The device exhibits a maximum insertion loss of 1.8 dB. Its physical dimensions are specified as 7.1 mm in length, 5.6 mm in width, and 4 mm in height.

Feature Summary

Band-pass filtering capability centered around 1.95 GHz
Surface-mount construction for automated assembly
RoHS compliant and lead-free manufacturing

Applications

Wireless communication systems requiring 1920-1980 MHz signal selection
RF front-end modules in mobile devices
Base station transceiver units

Procurement Notes

Verify the manufacturer designation as Tusonix, a subsidiary of CTS Electronic Components, to ensure authenticity. Confirm the RoHS compliance status and lead-free characteristics during sourcing. Ensure the packaging matches the Tape & Reel (TR) specification for surface-mount processing. Validate that the part number corresponds exactly to the CER0109B model to avoid substitution errors in high-frequency applications.

Selection Notes

Select this component when a compact ceramic filter is required for the 1920-1980 MHz band. Consider its 1.8 dB maximum insertion loss and 1W average power rating against system requirements. The 7.1x5.6x4 mm footprint must fit the designated PCB area. Verify compatibility with surface-mount reflow processes given the Monoblock package type.

Part Context

This component belongs to the passive components category, specifically under ceramic filters. It is part of the broader product line offered by Tusonix/CTS Electronic Components. The CER0109B serves as a specialized RF element distinct from general-purpose electronic parts, focusing on frequency discrimination in microwave applications.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Consult official CTS/Tusonix catalogs or authorized distributors for direct equivalents or pin-compatible alternatives before considering cross-references.
