ACH32C-222-TL001

Overview

The ACH32C-222-TL001 is a surface-mount EMI filter circuit manufactured by TDK Corporation, designed for power line applications. It features an LC (T) filter topology with a capacitance of 2200 pF and a rated voltage of 50 V. The component supports a current rating of 6 A and operates within a temperature range of -40°C to +125°C. Housed in a 1206 package measuring 3.2 mm x 1.6 mm x 2.1 mm, it provides attenuation of 20 dB across the 55 MHz to 300 MHz frequency range, with a cutoff frequency of 120 MHz.

Feature Summary

• Integrates ferrite beads and chip capacitors into a single compact SMD package
• Engineered to handle high current levels up to 6 A
• Provides effective EMI/RFI suppression in a small footprint

Applications

• General purpose EMI filtering
• Power line noise suppression
• Portable electronic devices

Procurement Notes

Verify the specific suffix TL001 against official TDK documentation to confirm packaging and marking details. Confirm availability status as distribution channels may vary. Ensure compatibility with existing PCB footprints and thermal management requirements before finalizing procurement decisions.

Selection Notes

Select this component when high current handling is required alongside significant EMI reduction in space-constrained designs. The 1206 form factor offers a balance between performance and board area. Verify that the 50 V rating and 6 A current capacity meet the specific circuit demands.

Part Context

This part belongs to the TDK ACH series of EMI filter circuits. These components combine passive filtering elements to suppress electromagnetic interference in DC power lines. The series is characterized by its ability to manage high currents while maintaining a low profile suitable for modern surface-mount assembly processes.

Replacement Considerations

Mouser lists YFF31AH2A104MTYN as a recommended alternative. Verify electrical parameters such as capacitance, current rating, and attenuation characteristics against the original specification to ensure functional equivalence.
