ACH3218-101-TD01

Overview

The ACH3218-101-TD01 is a third-order low-pass LC (T-type) EMI filter manufactured by TDK Corporation. Designed for power line applications, it features a single channel with a current rating of 1.5 A and a voltage rating of 20 V. The component utilizes a surface-mount 1210 (3225 metric) package with three PCB pads. It operates within a temperature range of -40°C to 125°C and provides attenuation of 25 dB at frequencies between 30 MHz and 85 MHz.

Feature Summary

• Third-order low-pass LC T-type topology for enhanced noise suppression
• Compact surface-mount design suitable for space-constrained layouts
• Rated for high current operation up to 1.5 A on power lines

Applications

• Power line filtering in general electronic equipment
• EMI suppression in data processing systems
• Industrial equipment noise reduction

Procurement Notes

Verify the specific suffix TD01 against the latest TDK datasheet to confirm pinout and termination details. Check RoHS compliance status as manufacturing processes may evolve. Confirm availability status as components in this series may be subject to discontinuation notices or lifecycle changes.

Selection Notes

Select this component when third-order attenuation is required for power lines carrying up to 1.5 A. Ensure the operating environment stays within the -40°C to 125°C range. Verify that the 1210 footprint fits the PCB layout constraints compared to similar first or second-order alternatives.

Part Context

This part belongs to the TDK ACH3218 series of 3-terminal filters designed for power line EMI suppression. The series offers various capacitance values and attenuation characteristics within the same compact 1210 package form factor, allowing designers to tailor noise filtering performance without changing mechanical dimensions.
