FK2125T207AL-T

Overview

The FK2125T207AL-T is a multilayer EMI suppression filter from the T series, manufactured by Taiyo Yuden. It features a T-type LC network configuration designed for single-channel data line protection. The component operates within a frequency range centered around 200 MHz with a tolerance of +/-40 MHz. It supports a maximum rated voltage of 10 V and a current rating of 100 mA. The DC resistance is specified at 2 Ohms. Housed in an 0805 (2012 metric) surface-mount package with three pads, it measures 2 mm in length, 1.25 mm in width, and 1.2 mm in height. The device functions reliably between -25°C and +85°C.

Feature Summary

• Multilayer ceramic construction for compact surface-mount integration
• T-type LC network topology for effective low-pass filtering
• Single-channel design optimized for signal integrity preservation

Applications

• Data lines for mobile devices
• High-speed digital signal protection
• EMI suppression in portable electronics

Procurement Notes

Verify component authenticity through authorized channels due to obsolete status. Confirm RoHS compliance details via official documentation before integration. Check for valid replacement options as original supply is discontinued. Ensure storage conditions match specified temperature ranges to maintain performance characteristics during handling and assembly processes.

Selection Notes

Select this component for applications requiring compact EMI filtering on single data lines. The 0805 footprint suits space-constrained designs. Verify that the 100 mA current rating meets circuit requirements. Consider the 2 Ohm resistance impact on signal attenuation. Evaluate thermal performance within the -25°C to +85°C operating range for target environment compatibility.
