LFL18915MTC5C311

Overview

The LFL18915MTC5C311 is a chip multilayer LC filter manufactured by Murata Electronics. It operates at a center frequency of 2.45 GHz with a bandwidth of 100 MHz. The device functions as a low-pass filter, exhibiting an insertion loss of 0.45 dB. Designed for surface mount technology, it utilizes a compact 0402 (1005 metric) package configuration. The physical dimensions are specified as 1.00 mm in length and 0.50 mm in width, with a maximum height of 0.40 mm.

Feature Summary

• Integrates inductor and capacitor elements within a single multilayer ceramic structure to achieve filtering functionality.
• Provides low-pass filtering characteristics suitable for suppressing unwanted high-frequency signals.
• Utilizes a small surface-mount footprint designed for automated assembly processes.

Applications

• Wireless LAN modules operating at 2.4 GHz bands
• Bluetooth communication interfaces
• Zigbee and other short-range wireless protocols

Procurement Notes

Verify the specific suffix codes against official Murata documentation to confirm exact electrical tolerances and termination specifications. Ensure compatibility with standard reflow soldering profiles for 0402 packages. Cross-reference part numbers with current obsolescence notices to avoid sourcing discontinued variants. Confirm RoHS compliance status through manufacturer datasheets prior to integration into regulated assemblies.

Selection Notes

Select this component when space constraints require a 0402 form factor for RF filtering applications. Evaluate insertion loss requirements against the 0.45 dB specification to ensure signal integrity is maintained. Consider thermal management capabilities relative to the small ceramic body size. Verify that the 100 MHz bandwidth aligns with the specific channel spacing requirements of the target wireless standard.

Part Context

This component belongs to the LFL series of chip multilayer LC filters from Murata Electronics. These devices are engineered to replace discrete LC networks, reducing board space and improving consistency. The series targets high-volume consumer electronics requiring reliable RF performance in minimal footprints.

Replacement Considerations

Consult official Murata substitution guides for verified alternatives. Generic equivalents may not match the precise impedance or parasitic characteristics required for 2.45 GHz operations.
