LFB215G37SG8A180

Overview

The LFB215G37SG8A180 is a multilayer ceramic bandpass filter manufactured by Murata Electronics. It operates at a center frequency of 5.375 GHz with a bandwidth of 475 MHz to 950 MHz, depending on the specific variant documentation. The component features an insertion loss of approximately 2.1 dB to 2.2 dB and a ripple of 1.8 dB. It is housed in a compact 0805 (2012 Metric) surface-mount package with four pads, measuring 2.00 mm x 1.25 mm x 1.05 mm max. Designed for 50Ω systems, it supports an operating temperature range of -40°C to +85°C and complies with RoHS3 standards.
