ACH3218-152-TD01

Overview

The TDK ACH3218-152-TD01 is a third-order low-pass LC(T-type) EMI filter designed for surface mount applications. It features a single channel with a rated voltage of 20V and a current capacity of 1.5A. The component exhibits a resistance of 0.06 ohms and provides attenuation of 25dB within the 30MHz to 85MHz frequency range. Housed in a 1210 (3225 metric) package measuring 3.20mm x 1.80mm x 2.75mm, it operates reliably between -40°C and +125°C.
