SLFB18-2R450G-23TF

Overview

The SLFB18-2R450G-23TF is a multilayer chip LC band pass filter manufactured by Shenzhen Sunlord Electronics Co., Ltd. It operates at a center frequency of 2.45 GHz with a bandwidth ranging from 2400 to 2500 MHz. The component features an insertion loss of 0.95 dB and provides attenuation of 20 dB at frequencies between 500 and 960 MHz, as well as 23 dB at 3200 MHz. It is housed in a 0603 (1608 metric) surface mount package with dimensions of 1.60mm x 0.80mm x 0.70mm maximum height.

Feature Summary

• Multilayer chip LC construction for RF filtering applications
• Surface mount design compatible with automated assembly processes
• High selectivity with specified attenuation levels outside the passband

Applications

• Wireless communication systems operating in the 2.4 GHz ISM band
• RF front-end modules requiring signal isolation
• Bluetooth and Wi-Fi device implementations

Procurement Notes

Verify the manufacturer part number SLFB18-2R450G-23TF against official Sunlord documentation to ensure authenticity. Confirm that the received components match the specified 0603 package dimensions and electrical characteristics. Check for proper packaging integrity and date codes to guarantee component reliability before integration into production lines.

Selection Notes

Select this component when a compact 0603 footprint is required for 2.45 GHz band pass filtering. Consider its 0.95 dB insertion loss and specific stopband attenuation requirements at 500-960 MHz and 3200 MHz. Ensure the surface mount technology capability aligns with the manufacturing process for reliable soldering and performance.

Part Context

This part belongs to the SLFB series of multilayer chip LC band pass filters from Shenzhen Sunlord Electronics. These components are designed for RF applications requiring small form factors and stable performance. The series utilizes LTCC or similar multilayer technology to achieve high Q factors and precise frequency response in miniature packages suitable for modern electronic devices.

Replacement Considerations

Consult official Sunlord documentation for direct substitutes within the SLFB series. Verify compatibility of alternative parts regarding center frequency, bandwidth, insertion loss, and physical dimensions to ensure seamless integration without redesigning the PCB layout.
