ACF451832-472-TD01

Overview

The ACF451832-472-TD01 is a third-order low-pass LC (T-type) EMI filter manufactured by TDK Corporation. It features a magnetic shielding structure using ferrite to provide excellent attenuation characteristics. The component is designed for signal line applications with a voltage rating of 50 V and a current rating of 300 mA. It operates within a temperature range of -25°C to an unspecified maximum limit, as per available documentation. The device utilizes surface-mount technology in an 1812 (4532 metric) package.

Feature Summary

• Third-order low-pass LC (T-type) circuit topology
• Ferrite magnetic shielding for enhanced attenuation
• Surface-mount design for compact integration

Applications

• Signal line EMI filtering in mobile devices
• Data line protection in consumer electronics
• General electromagnetic interference suppression in low-voltage circuits

Procurement Notes

Verify the specific suffix TD01 against the manufacturer's latest datasheet to confirm exact electrical tolerances and packaging specifications. Ensure compatibility with the target PCB footprint and thermal requirements before procurement. Confirm availability status as distribution channels may vary.

Selection Notes

Select this component for applications requiring high attenuation in a small form factor. The 300 mA current rating suits low-power signal lines. Verify that the 50 V voltage rating meets the system's operational limits. Consider the 1812 package size for space-constrained designs.

Part Context

This part belongs to the TDK ACF451832 series of shielded EMI filters. The series is characterized by its T-type LC configuration and ferrite shielding, offering superior noise suppression compared to unshielded alternatives. It is intended for use in portable electronic devices where space and performance are critical constraints.

Replacement Considerations

Consult the official TDK datasheet for direct pin-compatible substitutes within the same series. Cross-referencing with other manufacturers requires careful verification of inductance values, current ratings, and physical dimensions to ensure functional equivalence.
