SLFB21-2R450G-31TF

Overview

The SLFB21-2R450G-31TF is a multilayer LTCC band pass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. Designed for surface mount installation in the 0805 (2012 Metric) package, this component operates with a center frequency of 2450 MHz and a bandwidth of 100 MHz. It exhibits an insertion loss of 1.2 dB and provides a minimum attenuation of 15 dB at 1600 MHz. The device supports lead-free processing and RoHS compliance.

Feature Summary

• Utilizes LTCC technology for compact surface mount integration
• Provides specific band pass filtering centered at 2450 MHz
• Ensures signal isolation with defined attenuation characteristics

Applications

• Wireless communication systems requiring 2.4 GHz filtering
• RF front-end modules in mobile devices
• Industrial, scientific, and medical (ISM) radio equipment

Procurement Notes

Verify the exact part number SLFB21-2R450G-31TF against official manufacturer datasheets to confirm LTCC construction and 0805 package dimensions. Ensure compatibility with surface mount assembly processes and check for RoHS compliance status prior to procurement.

Selection Notes

Select this component when a 2.45 GHz center frequency with 100 MHz bandwidth is required. Consider the 1.2 dB insertion loss and 15 dB attenuation at 1600 MHz for system performance requirements. The 0805 footprint suits space-constrained PCB layouts.

Part Context

This component belongs to the SLFB series of multilayer chip filters from Shenzhen Sunlord Electronics. These filters are engineered for RF applications, offering reliable performance in compact surface mount packages suitable for modern electronic manufacturing standards.

Replacement Considerations

Consult official substitution lists for compatible LTCC band pass filters with identical 2450 MHz center frequency and 0805 dimensions. Verify electrical parameters match before replacing.
