SLFB15-2R450G-31TF

Overview

The SLFB15-2R450G-31TF is a multilayer chip LC band pass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. Designed for radio frequency applications, this component operates with a center frequency of 2.45 GHz and a bandwidth of 100 MHz. It features a low insertion loss of 1.3 dB and provides high attenuation, specifically a minimum of 9 dB at DC to 915 MHz and 34 dB minimum at specified stopbands. The device is housed in a compact 0402 (1005 Metric) surface mount package, suitable for space-constrained PCB layouts.

Feature Summary

• Multilayer LC technology for stable RF filtering performance
• Optimized for ISM band operations with precise center frequency control
• Compact 0402 surface mount footprint for automated assembly

Applications

• Wi-Fi module signal conditioning
• Bluetooth transceiver front-end filtering
• ISM band communication devices

Procurement Notes
