SLFB18-1R910G-01TF

Overview

The SLFB18-1R910G-01TF is a multilayer chip LC band pass filter from the SLFB series, manufactured by Shenzhen Sunlord Electronics Co., Ltd. Designed for radio frequency applications, this component operates at a center frequency of 1.91 GHz with a bandwidth of 220 MHz. It features a maximum insertion loss of 1.7 dB and provides attenuation of 30 dB minimum at frequencies between 700 MHz and 950 MHz. The device utilizes a surface mount package in the 0603 (1608 Metric) dimension, specifically configured with four printed circuit board pads. It is supplied in tape and reel packaging and maintains an active product status.

Feature Summary

• Multilayer LC technology for compact RF filtering
• Surface mount construction for automated assembly
• High selectivity with specified stopband attenuation

Applications

• Wireless communication modules
• RF front-end circuits
• Mobile device signal processing

Procurement Notes

Verify the complete part number including suffixes to ensure correct packaging and specifications. Confirm that the 0603 footprint matches the target PCB layout. Check datasheet revisions for any updates to electrical characteristics or recommended soldering profiles before integration into production designs.

Selection Notes

Select this component when a 1.91 GHz center frequency is required within a constrained 0603 footprint. Consider the 220 MHz bandwidth and 1.7 dB insertion loss against system link budget requirements. Ensure compatibility with surface mount assembly processes and verify thermal management needs for the specific application environment.

Part Context

This component belongs to the SLFB series of multilayer chip filters produced by Shenzhen Sunlord Electronics Co., Ltd. The series is engineered for high-performance RF applications requiring small form factors. Sunlord specializes in passive electronic components, including magnetic devices and microwave components, serving industries such as telecommunications and consumer electronics.

Replacement Considerations

Direct substitutes must match the 1.91 GHz center frequency, 0603 package, and similar electrical parameters. Verify pinout compatibility and mounting pad dimensions. Cross-reference with other manufacturers' RF bandpass filters offering comparable insertion loss and stopband rejection characteristics.
