SLFB18-2R450G-36TF

Overview

The SLFB18-2R450G-36TF is a multilayer LTCC bandpass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. It operates at a center frequency of 2450 MHz with an absolute bandwidth of 2400–2500 MHz. The component features an insertion loss of 0.95 dB and provides attenuation of 20 dB within the 500–960 MHz range, alongside 23 dB attenuation at 3200 MHz. It utilizes a surface-mount 0603 (1608 Metric) package with four pads.

Feature Summary

• Multilayer LTCC construction for compact surface-mount integration
• Bandpass filtering capability centered at 2450 MHz
• Defined attenuation characteristics in specified stopband ranges

Applications

• Wireless communication systems requiring 2.4 GHz signal selection
• RF front-end modules for mobile devices
• Industrial, Scientific, and Medical (ISM) radio equipment

Procurement Notes

Verify the specific datasheet version against the manufacturer's official documentation before ordering. Confirm that the 0603 package dimensions and pad layout match your PCB design requirements. Ensure the operating temperature range aligns with your system's environmental conditions. Cross-reference the part number to distinguish between similar variants in the SLFB series.

Selection Notes

Select this component when a low-profile bandpass filter is required for 2.45 GHz applications. The 0603 footprint suits space-constrained designs. Evaluate the 0.95 dB insertion loss against system link budget requirements. Consider the LTCC technology for stability in varying thermal environments compared to other filter types.
