FK2125TZ700C500T

Overview

The FK2125TZ700C500T is a multilayer EMI suppression filter from the TZ series, manufactured by Taiyo Yuden. It features an RC (T-Type) low-pass configuration designed for audio frequency range distortion reduction. The component operates in a 0805 (2012 metric) surface-mount package with dimensions of 2.0mm x 1.25mm. Key electrical specifications include a resistance of 70 Ohms and a capacitance of 50pF. It supports a maximum current of 100 mA and functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates RC T-type topology for effective EMI/RFI filtering
• Optimized for audio frequency range distortion reduction
• Compact 0805 surface-mount footprint for space-constrained designs

Applications

• Audio signal line filtering
• EMI suppression in consumer electronics
