FI105L250014-T

Overview

The FI105L250014-T is a multilayer ceramic low-pass filter manufactured by Taiyo Yuden. It operates within the 2.4 GHz to 2.5 GHz frequency range and is designed for surface-mount applications. The component utilizes a 0402 (1005 metric) package with four pins and a 50-ohm impedance. It is engineered to attenuate higher-frequency signals while passing lower frequencies, suitable for RF signal conditioning in compact electronic designs.

Feature Summary

• Multilayer ceramic construction for reliable high-frequency performance
• Low-pass filtering characteristic optimized for specific RF bands
• Compact 0402 surface-mount footprint for space-constrained layouts

Applications

• RF signal conditioning in wireless communication modules
• Harmonic suppression in transmitter output stages
• Interference filtering in mobile device RF front-ends
