SLFB21-2R450G-02TF

Overview

The SLFB21-2R450G-02TF is a multilayer chip LC 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 2.45 GHz and a bandwidth of 100 MHz. It exhibits a typical insertion loss of 1.9 dB. The device provides high attenuation in stopbands, specifically achieving a minimum of 35 dB at frequencies between 824 MHz and 960 MHz, and a minimum of 30 dB at other specified out-of-band ranges.

Feature Summary

• Multilayer chip LC construction for compact surface mount integration
• Band pass filtering capability centered at 2.45 GHz
• High selectivity with significant attenuation in adjacent frequency bands

Applications

• Wireless LAN systems operating in the 2.4 GHz ISM band
• Bluetooth communication modules
• Zigbee and other 2.4 GHz IoT devices

Procurement Notes

Verify the specific suffix codes against the manufacturer's official datasheet to ensure correct electrical characteristics and packaging options. Confirm that the 0805 package dimensions align with your PCB footprint requirements. Check for any recent revisions to the product specifications or lead times directly with Shenzhen Sunlord Electronics Co., Ltd. before finalizing procurement plans.

Selection Notes

Select this component when a compact band pass filter is required for 2.45 GHz applications with strict size constraints. The 0805 package offers a balance between performance and board space efficiency. Ensure the application environment does not exceed the component's thermal and voltage ratings as defined in the official documentation.
