LFB215G12SG8A183

Overview

The Murata LFB215G12SG8A183 is a ceramic bandpass filter designed for RF applications. It operates with a center frequency of 5125 MHz and features a bandwidth of 225 MHz. The component utilizes a surface-mount 0805 (2012 Metric) package with four pads, measuring 2.00mm in length, 1.25mm in width, and 1.05mm in maximum height. It maintains a 50 Ohm impedance and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Provides precise signal selection through defined center frequency and bandwidth characteristics
• Utilizes compact surface-mount construction for efficient PCB integration
• Ensures stable performance across specified industrial temperature ranges

Applications

• RF front-end filtering in wireless communication modules
• Signal conditioning in microwave transceiver circuits
• Interference suppression in high-frequency data transmission systems

Procurement Notes

Verify current availability status as the component may be subject to obsolescence notices. Confirm that the specific ordering suffix matches required specifications, as variations can alter electrical parameters. Ensure compliance with RoHS directives if applicable to your manufacturing standards. Cross-reference datasheet revisions to confirm pinout and dimensional consistency before finalizing procurement orders.

Selection Notes

Select this component when a 5125 MHz center frequency with 225 MHz bandwidth is required. The 0805 footprint suits space-constrained designs needing 50 Ohm impedance matching. Consider thermal limits between -40°C and +85°C during system design. Evaluate insertion loss and ripple specifications against link budget requirements to ensure adequate signal integrity in the target application environment.
