Overview

The B285LB2S-T is a surface-mount bandpass filter manufactured by Knowles Dielectric Labs, designed for microwave applications. It operates at a center frequency of 28.0 GHz with a bandwidth of 2 GHz. The component features a 50 Ohm impedance and an insertion loss of 3.5 dB. It utilizes a 2-SMD, no-lead package suitable for board mounting. The device supports a minimum operating temperature of -55°C and a maximum operating temperature of +125°C.

Feature Summary

Fully shielded construction utilizing low-loss, high permittivity ceramics to ensure minimal performance variation over temperature.
Designed as a drop-in solution for high-frequency attenuation in signal conditioning circuits.
100% tested and inspected to guarantee excellent repeatability and reliability.

Applications

Microwave communication systems
High-frequency signal conditioning
Bandpass filtering in RF front-ends

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm RoHS compliance status through official documentation. Check current supply availability as distribution may be restricted. Ensure the 28.0 GHz frequency aligns with system requirements before procurement.

Selection Notes

Select this component for applications requiring precise 28.0 GHz bandpass filtering with a 2 GHz bandwidth. Consider the 50 Ohm impedance match for standard RF interfaces. Evaluate the SMD package size against PCB layout constraints. Verify thermal stability requirements against the specified -55°C to +125°C operating range.
