SLFB18-2R450G-07TF

Overview

The SLFB18-2R450G-07TF is a multilayer LTCC band pass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. It features a center frequency of 2450 MHz and a bandwidth of 100 MHz, with an insertion loss of 1.8 dB. The component provides high attenuation in specific out-of-band regions, offering a minimum rejection of 30 dB at frequencies ranging from 800 to 960 MHz, 1710 to 1990 MHz, 4800 to 5000 MHz, and 7200 to 7500 MHz. Designed for radio frequency applications, it utilizes a compact 0603 (1608 Metric) surface-mount package.

Feature Summary

• Multilayer LTCC construction for reliable RF filtering
• High selectivity with defined stopband rejection zones
• Compact 0603 surface-mount form factor

Applications

• Wireless communication systems operating near 2.4 GHz
• RF front-end modules requiring signal isolation
• Mobile device antenna interfaces

Procurement Notes

Verify the complete part number including suffixes such as '07TF' against official manufacturer documentation to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead-free requirements with the supplier prior to ordering. Cross-reference datasheet revision dates to validate current electrical parameters and mechanical dimensions.

Selection Notes

Select this component when a narrow bandpass characteristic centered at 2.45 GHz is required within a constrained PCB area. The 0603 footprint suits high-density layouts. Ensure system requirements align with the specified 1.8 dB insertion loss and the specific stopband attenuation levels provided for interference mitigation in adjacent frequency bands.

Part Context

This component belongs to the SLFB series of multilayer chip LC band pass filters produced by Shenzhen Sunlord Electronics. The series utilizes Low-Temperature Co-fired Ceramic (LTCC) technology to achieve stable performance in radio frequency environments. The SLFB18 designation indicates the specific family characteristics, while the numeric suffix defines the center frequency and bandwidth parameters.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Verify compatibility with alternative components by matching center frequency, bandwidth, insertion loss, and physical package dimensions.
