B057MC5S

Overview

The B057MC5S is a surface mount bandpass filter manufactured by Knowles Dielectric Labs, designed for signal conditioning applications. It operates at a center frequency of 5.7 GHz with a bandwidth of 500 MHz. The component features an insertion loss of 2.5 dB and is housed in a compact 3-SMD, no-lead package measuring 8.89 mm in length and 5.08 mm in width.

Feature Summary

• Surface mount construction for automated assembly
• Bandpass filtering capability centered at 5.7 GHz
• Low insertion loss design for efficient signal transmission

Applications

• RF signal conditioning circuits
• Wireless communication systems operating in the 5.7 GHz range
• Microwave filter assemblies

Procurement Notes

Verify that the specific variant required matches the base part number B057MC5S rather than the tape-and-reel version B057MC5S-T if bulk packaging is preferred. Confirm mechanical compatibility with the 3-SMD footprint dimensions of 8.89mm x 5.08mm during PCB layout. Ensure the application environment supports the specified electrical characteristics for the 5.7 GHz center frequency.

Selection Notes

Select this component when a precise 500 MHz bandwidth is required around the 5.7 GHz center frequency. Consider the 2.5 dB insertion loss specification against system link budget requirements. The surface mount form factor makes it suitable for space-constrained high-frequency designs where leaded alternatives are unsuitable.

Part Context

This part belongs to the Bandpass Filter subcategory within Knowles Dielectric Labs' signal conditioning portfolio. It shares the manufacturer's focus on high-performance RF components but differs from other models like B099NC4S-T which operate at different frequencies such as 10.25 GHz. The B057MC5S represents a specific solution for C-band or similar microwave applications.
