ACH32C-331-TL001

Overview

The ACH32C-331-TL001 is a third-order LC (T-Type) EMI filter manufactured by TDK Corporation, designed for power line applications. It features a capacitance of 330 pF and supports a rated current of 6 A at 50 V. The component utilizes surface-mount technology in a 1206 (3216 metric) package with dimensions of 3.2 mm x 1.6 mm x 2.1 mm. It operates within a temperature range of -40°C to +125°C and provides attenuation characteristics suitable for high-current circuits.

Feature Summary

• Third-order LC T-type EMC filter structure integrating ferrite beads and chip capacitors
• Engineered to handle high current levels for power line filtering
• Vertical mounting design eliminates the need for additional mounting space
• Capable of achieving excellent attenuation characteristics when used with stable grounds

Applications

• Home electronic devices such as TVs, VTRs, CD players, and electronic musical instruments
• Office automation equipment including computers, terminals, and facsimiles
• Factory automation equipment like robots, NC machine tools, and process controllers

Procurement Notes

Verify the specific suffix TL001 against official TDK documentation to confirm packaging and tape specifications. Confirm availability status as distribution channels may vary. Ensure compatibility with reflow soldering conditions specified in the datasheet. Validate that the application environment falls within the guaranteed temperature range of -40 to +125°C. Check for any regional sales restrictions or end-of-life notices before finalizing procurement plans.

Selection Notes

Select this component for circuits requiring high-current handling capabilities up to 6 A. Ensure the design allows for stable ground connections to maximize attenuation performance. Consider the vertical mounting profile for high-density PCB layouts where space is limited. Verify that the operating voltage does not exceed the 50 V rating. Confirm that the target application is not an automotive ECU, as this series is explicitly excluded from such use cases.

Part Context

This part belongs to the ACH series of 3-terminal filters for power lines. The series is characterized by its ability to manage large currents while maintaining compact dimensions. It is distinct from other TDK filter families by its specific T-type topology and vertical form factor, optimized for suppressing electromagnetic interference in general-purpose electronic equipment.
