B119MB1S-T

Overview

The B119MB1S-T is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It operates at a center frequency of 11.9 GHz and is intended for Ku-band satellite communications. The component features a 50 Ohm impedance and utilizes SMD/SMT termination types for board mounting. It is supplied in a reel package format. The device supports an operating temperature range from -55°C to +125°C.

Feature Summary

• Surface mount construction for automated assembly
• Bandpass filtering capability for signal conditioning
• Ku-band operation suitable for satellite communications

Applications

• Satellite communications systems
• Ku-band signal processing
• Microwave circuit design

Procurement Notes

Verify the specific datasheet version and mechanical dimensions prior to integration. Confirm that the reel packaging aligns with your pick-and-place equipment specifications. Ensure thermal management strategies accommodate the specified operating temperature range during final assembly and deployment.

Selection Notes

Select this component when a fixed center frequency of 11.9 GHz is required for Ku-band applications. Consider the surface mount form factor for space-constrained PCB layouts. Validate impedance matching requirements against the system's 50 Ohm standard before finalizing the design.

Part Context

This part belongs to the Bandpass filter series within the Knowles Dielectric Labs portfolio. It is categorized under Signal Conditioning products. The manufacturer specializes in precision passive components for high-frequency applications, including microwave and RF circuits.

Replacement Considerations

Check for direct substitutes such as the B119MB1S (bulk package) if reel availability is constrained. Verify electrical equivalence for other Ku-band filters like the B142LA2S only if frequency parameters allow.
