LFD182G45DP4B720

Overview

The LFD182G45DP4B720 is a chip multilayer diplexer manufactured by Murata Electronics, designed for RF signal conditioning applications. It utilizes a ceramic microwave filter architecture to manage frequency bands within compact electronic systems. The component features a 4-pin configuration and is housed in a standard 0603 (1608 Metric) surface-mount package, measuring 1.60mm x 0.80mm. This device integrates multiple filtering functions into a single small form factor, enabling efficient space utilization in mobile and wireless communication devices while maintaining signal integrity across specified bandwidths.

Feature Summary

• Integrates multi-functional LC filtering capabilities within a monolithic ceramic structure
• Provides dedicated diplexer functionality for simultaneous signal path separation
• Utilizes a compact 0603 surface-mount footprint for high-density PCB layouts

Applications

• Bluetooth module integration
• Wireless LAN (WLAN) front-end circuits
• Mobile phone RF transceivers

Procurement Notes

Verify the specific suffix 'B720' against official Murata documentation to confirm tape-and-reel specifications and exact electrical tolerances. Ensure compatibility with automated pick-and-place equipment regarding the 0603 package dimensions. Cross-reference the RoHS compliance status with current regulatory requirements for the target market. Confirm that the 4-pin pad layout matches the design footprint before finalizing procurement orders.

Selection Notes

Select this component when a dual-band or multi-path filtering solution is required in a constrained board area. The 0603 size offers a balance between performance and miniaturization compared to larger discrete filters. Consider the ceramic construction for thermal stability in varying environmental conditions. Evaluate the insertion loss and isolation characteristics against system link budget requirements to ensure adequate signal fidelity.

Part Context

This part belongs to Murata's line of ceramic microwave filters, specifically the LFD series which focuses on signal conditioning. These components are engineered for high-volume consumer electronics manufacturing. The diplexer variant allows for the combination or separation of different frequency signals, reducing the need for multiple discrete components and simplifying the overall RF circuit design.
