ACF321825-472-TD01

Overview

The ACF321825-472-TD01 is a vertically mounted LC T-type EMI filter designed for high-density circuit applications. It features a single channel with a 300 mA current rating and a 20 V rated voltage. The component exhibits a channel resistance of 0.15 Ω and provides 25 dB attenuation across the 30 MHz to 85 MHz frequency range. Housed in a 1210 (3225 Metric) surface-mount package with three pads, it supports reflow soldering processes.

Feature Summary

• Vertical mounting design minimizes required board space for high-density layouts
• LC T-type topology integrates signal line filtering capabilities
• Surface-mount construction compatible with standard reflow soldering

Applications

• Signal line EMI suppression
• High-density electronic circuit designs
• General-purpose noise filtering

Procurement Notes

Verify component status as this part is classified as End-of-Life or Not Recommended for New Designs. Confirm availability through authorized distributors or secondary markets. Ensure replacement strategies account for discontinued manufacturing status and potential supply chain limitations when integrating this component into new production cycles.

Selection Notes

Select this component for designs requiring vertical footprint reduction and specific LC T-type filtering characteristics. Evaluate the 300 mA current limit and 20 V rating against circuit requirements. Consider the 1210 package dimensions for spatial constraints. Verify compatibility with reflow soldering profiles during assembly planning.

Part Context

This component belongs to the TDK ACF series, which specializes in vertically mounted filters to optimize board real estate. The series targets applications where space efficiency is critical. The ACF321825-472-TD01 specifically utilizes a 1210 footprint with three connection pads, distinguishing it from standard two-pad SMD components.
