ACF451832-153-TLD01

Overview

The ACF451832-153-TLD01 is a three-terminal surface-mount EMI filter manufactured by TDK Corporation. It utilizes an LC T-type circuit topology with magnetic shielding provided by ferrite materials to achieve superior attenuation characteristics. The component operates at a rated voltage of 50V and supports a maximum current of 300mA. Designed for signal line applications, it features a compact 1812 (4532 metric) package with three PCB pads. The device functions as a third-order low-pass filter with a single channel, offering effective noise suppression in electronic circuits.

Feature Summary

• Magnetic shielding using ferrite materials for enhanced performance
• T-type LC filter circuit topology for superior attenuation
• Three-terminal surface mount design for signal lines

Applications

• Data lines for mobile devices

Procurement Notes

This component is officially listed as obsolete and no longer manufactured by TDK Corporation. Procurement should focus on verifying the authenticity of existing stock from authorized distributors or secondary market suppliers. Ensure that any available units are new old stock to guarantee reliability. Cross-reference part numbers carefully as suffixes may indicate variations in packaging or tape specifications rather than functional changes.

Selection Notes

Select this component only if legacy compatibility is required for designs originally specifying the ACF451832 series. Verify that the 300mA current rating and 50V voltage limit meet the specific circuit requirements. Consider the physical dimensions of the 1812 package during PCB layout planning. Since the part is obsolete, evaluate alternative modern equivalents that offer similar attenuation profiles and form factors for new production runs.

Part Context

The ACF451832-153-TLD01 belongs to TDK's ACF series of EMI filters. This series is characterized by products with superior attenuation characteristics achieved through magnetic shielding with ferrite. The specific model indicates a T-type filter configuration designed for high-frequency noise suppression in compact electronic assemblies.

Replacement Considerations

As the ACF451832-153-TLD01 is obsolete, direct replacement requires identifying equivalent LC T-type filters with comparable 300mA ratings and 1812 footprints. Verify attenuation curves and impedance matching against original design specifications to ensure continued electromagnetic interference suppression effectiveness.
