ACF451832-223-TLD01

Overview

The TDK ACF451832-223-TLD01 is a signal line EMI filter designed for third-order low-pass filtering in a single channel. It utilizes an LC (T-Type) circuit topology to suppress electromagnetic interference on data lines. The component features a rated voltage of 50 V and a current rating of 300 mA. It operates within a temperature range of -25°C to 85°C and is housed in a compact 1812 surface-mount package.

Feature Summary

• Provides third-order low-pass filtering characteristics for effective noise suppression
• Utilizes LC T-type circuit topology for single-channel signal line protection
• Designed specifically for high-density surface-mount applications

Applications

• Data lines for mobile devices
• Signal line EMI filtering in consumer electronics
• Noise suppression in portable communication equipment

Procurement Notes

Verify the specific ordering suffix, as variations such as TD01 or TLD01 may exist within the product family. Confirm availability status, as this component may be classified as Not For New Designs or discontinued by the manufacturer. Ensure the selected variant matches the required termination style and package dimensions for the target PCB layout.

Selection Notes

Select this component when third-order attenuation is required for single-channel data lines. Verify that the operating current does not exceed 300 mA and the voltage remains below 50 V. Ensure the 1812 footprint aligns with the design constraints and that the -25°C to 85°C temperature range meets the environmental requirements of the application.

Part Context

This part belongs to the TDK ACF series of EMI/RFI filters. These components are engineered for use in space-constrained environments where high-performance noise filtering is necessary without increasing board size. The series typically offers various cutoff frequencies and current ratings to suit different signal integrity needs.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official TDK resources for cross-reference information if alternative sourcing is required.
