FK2125T186AL-T

Overview

The FK2125T186AL-T is a multilayer EMI suppression filter manufactured by Taiyo Yuden. It features an LC (T-type) low-pass configuration with three components in a single package. The device operates at a cutoff frequency of 18 MHz and has a maximum voltage rating of 10 V. It supports a continuous current of 100 mA and exhibits a resistance of 2 Ohms. The component is housed in a standard 0805 surface-mount package, measuring 2 mm in length, 1.25 mm in width, and 1.05 mm in height.

Feature Summary

• Integrates LC T-type topology for compact EMI filtering
• Provides third-order low-pass signal attenuation
• Designed for high-frequency noise suppression in RF circuits

Applications

• LTE module noise filtering
• RF circuit interference suppression
• High-speed digital line protection

Procurement Notes

Verify the exact suffix AL-T against official Taiyo Yuden documentation to confirm the specific 18 MHz cutoff characteristic. Ensure compatibility with 10 V operating limits and 100 mA current ratings for the target application. Confirm RoHS compliance status through the manufacturer's latest datasheet before integration.

Selection Notes

Select this component when a compact, third-order low-pass filter is required for LTE or RF applications. The 0805 footprint suits space-constrained designs. Verify that the 18 MHz cutoff aligns with the signal bandwidth requirements and that the 2 Ohm resistance does not impact DC bias conditions.
