B042OD4S-T

Overview

The B042OD4S-T is a surface-mount bandpass filter manufactured by Knowles Dielectric Labs. It operates at a center frequency of 4.25 GHz with a bandwidth of 1 GHz and an insertion loss of 3.5 dB. The component utilizes a 2-SMD, no-lead package design suitable for high-frequency signal conditioning applications.

Feature Summary

Surface-mount thin-film construction on high dielectric constant ceramic
Designed for 50Ω microwave applications
Optimized for RF signal filtering

Applications

Microwave circuit signal conditioning
RF system frequency selection
High-frequency communication equipment

Procurement Notes

Verify the specific datasheet for the B042OD4S-T variant to confirm electrical tolerances and thermal characteristics. Ensure compatibility with the target PCB footprint and reflow soldering profiles. Cross-reference the manufacturer's latest documentation for any updates regarding material composition or environmental compliance standards before finalizing procurement.

Selection Notes

Select this component when a 4.25 GHz center frequency and 1 GHz bandwidth are required in a compact surface-mount form factor. Consider the 3.5 dB insertion loss specification against system link budget requirements. Evaluate the 2-SMD no-lead package constraints for automated assembly processes and spatial limitations within the target electronic device architecture.

Part Context

This part belongs to the AFL Bandpass Filter series from Knowles Dielectric Labs. These filters are characterized as surface-mount, thin-film devices built on high dielectric constant ceramic substrates. They are engineered specifically for high-performance 50Ω microwave applications requiring precise frequency control.

Replacement Considerations

Consult official substitution lists for equivalent 4.25 GHz bandpass filters. Verify that alternative components match the 1 GHz bandwidth and 3.5 dB insertion loss specifications. Ensure physical package dimensions and pinout configurations are compatible with existing board layouts.
