ACH32C-220-TL001

Overview

The ACH32C-220-TL001 is a surface-mount EMI filter circuit manufactured by TDK Corporation. It utilizes an LC (T-type) filter topology designed for power line applications. The component features a capacitance of 22 pF and supports a rated current of 6 A with a voltage rating of 50 V. It operates within a frequency range of 55 MHz to 300 MHz, providing attenuation of -15 dB at 1.3 GHz to 2.5 GHz. The device is housed in a 1206 (3216 metric) package with dimensions of 3.2 mm x 1.6 mm x 2.1 mm. It functions reliably between -40°C and +125°C.

Feature Summary

• Engineered to handle high current levels using ferrite beads and chip capacitors
• Designed specifically for large current power line applications
• Provides effective electromagnetic compatibility filtering in a compact SMD form factor

Applications

• Power line filtering in electronic circuits
• EMI suppression for high-current signal paths
• Electromagnetic compatibility enhancement in consumer electronics

Procurement Notes

Verify the specific suffix TL001 against official TDK documentation to confirm packaging and tape specifications. Confirm end-of-life status as some sources indicate discontinuation. Ensure the selected variant matches the required capacitance and current ratings for the target application before ordering.

Selection Notes

Select this component when high current handling up to 6 A is required alongside EMI suppression. The 1206 package offers a balance between current capacity and board space. Verify that the 22 pF capacitance aligns with the desired cutoff frequency characteristics for the specific noise spectrum being addressed.

Part Context

This part belongs to the TDK ACH series of third-order low-pass filters. These components integrate ferrite beads with chip capacitors to create T-type networks. The series is characterized by its ability to manage significant current loads while maintaining small physical footprints suitable for modern surface-mount assembly processes.

Replacement Considerations

Official substitutes may include other parts from the ACH series with adjusted capacitance values. Cross-reference with manufacturer datasheets for direct pin-compatible alternatives if the exact model is unavailable.
