ACF451832-151-TLD01

Overview

The ACF451832-151-TLD01 is a signal line EMI filter from TDK Corporation, designed for electromagnetic compatibility applications. It utilizes an LC (T-type) circuit topology that integrates ferrite chip beads and multilayer ceramic chip capacitors within a single component. The device operates with a voltage rating of 50 V and a current rating of 300 mA. It features a cutoff frequency of 230 MHz and is housed in an 1812 (4532 metric) surface-mount package.

Feature Summary

• Integrates ferrite chip beads and multilayer ceramic chip capacitors into a compact T-type EMC filter structure
• Provides effective attenuation for electromagnetic interference on signal lines
• Designed for surface-mount assembly to facilitate automated PCB manufacturing

Applications

• Signal line filtering in electronic circuits
• Electromagnetic compatibility enhancement in consumer electronics
• Noise suppression in high-speed data transmission paths

Procurement Notes

Verify the specific suffix 'TLD01' against official TDK documentation to confirm tape-and-reel packaging and terminal configuration. Ensure the component meets required RoHS compliance standards for your target market. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm availability status as supply chain conditions may vary.

Selection Notes

Select this component when a compact solution is needed for signal line EMI suppression. The 1812 package size offers a balance between performance and board space efficiency. Consider the 300 mA current rating and 50 V voltage limit during circuit design. The 230 MHz cutoff frequency determines the frequency range of noise attenuation provided by the filter.

Part Context

This component belongs to the ACF series of T-type EMC filters manufactured by TDK Corporation. These filters are engineered to replace discrete component arrangements, simplifying circuit design and reducing footprint. The series incorporates advanced materials to achieve high performance in small packages suitable for modern portable devices.

Replacement Considerations

Consult TDK's official substitution guide for verified alternatives. Ensure any replacement maintains the same LC (T-type) topology and package dimensions. Verify that electrical ratings such as current, voltage, and cutoff frequency meet or exceed original requirements.
