B040JC6S-T

Overview

The B040JC6S-T is a surface-mount bandpass filter manufactured by Knowles Dielectric Labs. It operates at a center frequency of 4 GHz with a bandwidth of 100 MHz. The component features a 3.5 dB insertion loss and a 50 Ohm impedance. Designed for board mounting, it utilizes an SMD/SMT termination type. The device is housed in a 3-SMD, no-lead package configuration.

Feature Summary

• Surface-mount ceramic construction for reliable RF signal conditioning
• Bandpass filtering capability centered at 4 GHz
• Designed for direct board mounting applications

Applications

• RF signal processing circuits
• Wireless communication systems
• Radio frequency front-end modules

Procurement Notes

Verify the specific suffix designation against official manufacturer documentation to confirm exact electrical tolerances and packaging variations. Ensure compatibility with existing PCB footprint requirements and thermal management specifications before integration into final designs.

Selection Notes

Select this component when a fixed 4 GHz center frequency with narrow 100 MHz bandwidth is required. Consider the 3.5 dB insertion loss impact on system gain budget. Confirm that the 3-SMD no-lead package aligns with available assembly equipment capabilities.

Part Context

This part belongs to the Knowles Dielectric Labs RF filter portfolio, specifically within their ceramic bandpass filter series. These components are engineered for high-frequency applications requiring precise frequency selection and rejection of out-of-band signals in compact form factors.

Replacement Considerations

Cross-reference with other DLI models offering identical 4 GHz center frequency and 100 MHz bandwidth. Verify pinout compatibility and mechanical dimensions to ensure seamless substitution without redesigning the host circuit board.
