ACH4518-151-TD01

Overview

The TDK ACH4518-151-TD01 is a three-terminal LC(T) EMI filter designed for high-current DC power lines. It operates within a frequency range of 235 MHz to 335 MHz, providing attenuation in this band. The component features a capacitance of 50 pF and supports a continuous current rating of 2.0 A at a voltage rating of 50 V. Housed in an SMD 1812 (4532 metric) package with three PCB contacts, it functions as a third-order low-pass filter. The unit has a channel count of one and exhibits a resistance of 0.06 Ohms.

Feature Summary

• Three-terminal LC(T) architecture optimized for stable ground circuits
• High-current handling capability suitable for DC power line applications
• Compact surface-mount form factor for space-constrained designs

Applications

• DC power line filtering in electronic equipment
• EMI suppression in high-current signal paths
