SLFBF21-2R450G-B01T

Overview

The SLFBF21-2R450G-B01T is a balanced RF bandpass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. It operates at a center frequency of 2.45GHz with a bandwidth of 100MHz and an insertion loss of 3.4dB. The component utilizes a surface-mount 0805 (2012 Metric) package, measuring 2.0mm in length, 1.25mm in width, and 1.0mm in maximum height. Designed for radio frequency applications, it provides signal filtering capabilities within the specified frequency range.

Feature Summary

• Balanced architecture designed for differential signal processing in RF circuits
• Surface-mount construction compatible with automated assembly processes
• Compact footprint suitable for space-constrained electronic designs

Applications

• Wireless local area network (WLAN) systems operating in the 2.4GHz ISM band
• Bluetooth communication modules requiring signal isolation
• Industrial, scientific, and medical (ISM) radio equipment

Procurement Notes

Verify the specific suffix B01T against official datasheets to confirm balanced configuration and termination requirements. Ensure compatibility with 0805 land patterns during PCB layout. Confirm RoHS compliance status through current manufacturer documentation before integration into regulated products.

Selection Notes

Select this component when a balanced filter topology is required for 2.45GHz applications. Compare insertion loss specifications against system link budget requirements. Evaluate the 0805 package dimensions against available board real estate constraints relative to alternative unbalanced filter options.

Part Context

This part belongs to the SLFB series of RF filters from Shenzhen Sunlord Electronics. The series includes various center frequencies and bandwidths tailored for wireless communication standards. The balanced variant distinguishes itself by supporting differential signal paths, offering improved common-mode rejection compared to single-ended counterparts.

Replacement Considerations

Consult official substitution lists for equivalent balanced filters with matching 2.45GHz center frequency and 0805 package dimensions. Verify that alternative components maintain similar insertion loss characteristics and bandwidth specifications to ensure circuit performance parity.
