ACF321825-102-TD01

Overview

The ACF321825-102-TD01 is a T-type EMI filter from the ACF series, integrating ferrite chip beads and multilayer ceramic capacitors. It functions as a third-order low-pass LC filter with one channel. The component supports a current rating of 300 mA and a voltage rating of 20 VDC. It provides an attenuation of 25 dB within the frequency range of 80 MHz to 140 MHz. The device operates between -25°C and 85°C and utilizes a 1210 (3225 Metric) surface mount package.

Feature Summary

• Integrates ferrite chip beads and multilayer ceramic capacitors into a single T-type structure for enhanced EMC suppression.
• Provides third-order low-pass filtering characteristics to effectively attenuate high-frequency noise.
• Designed for signal line applications requiring compact surface mount solutions.

Applications

• Mobile device data lines
• Signal line EMI filtering
• General purpose power line filtering
