CER0311B

Overview

The CER0311B is a ceramic bandpass filter manufactured by Tusonix, a subsidiary of CTS Electronic Components. It operates within the frequency range of 3700 MHz to 3800 MHz. The component utilizes a surface-mount device (SMD/SMT) termination style for integration into circuit boards. Its physical dimensions are specified as 11.75 mm in length, 5.4 mm in width, and 4.6 mm in height. This passive electronic component is designed for signal conditioning applications requiring specific RF filtering characteristics.

Feature Summary

• Provides bandpass filtering functionality for radio frequency signals
• Utilizes ceramic dielectric material for stable performance
• Designed for surface-mount assembly on printed circuit boards

Applications

• RF signal conditioning circuits
• Radio frequency interference filtering
• Wireless communication system front-ends

Procurement Notes

Verify manufacturer documentation from CTS Electronic Components or Tusonix to confirm current RoHS compliance status and lead times. Ensure the ordering suffix matches the required package variant. Cross-reference with official distributor catalogs to validate authenticity and avoid counterfeit components. Confirm that the SMD footprint aligns with the design layout specifications.

Selection Notes

Select this component when a fixed center frequency between 3.7 GHz and 3.8 GHz is required. Consider the physical size constraints of the PCB layout against the 11.75 x 5.4 x 4.6 mm dimensions. Evaluate the need for ceramic filter technology over other types based on insertion loss and bandwidth requirements for the specific RF application.
