ACF451832-102-TLD01

Overview

The TDK ACF451832-102-TLD01 is a signal line EMI filter circuit from the ACF series. It operates with a voltage rating of 50 V and a current rating of 300 mA. The component utilizes an LC (T) filter topology and features SMD/SMT termination styles within an 1812 package. Its cutoff frequency is specified at 100 MHz, with an operating temperature range extending from -25°C to higher limits.

Feature Summary

• Incorporates a T-type EMC filter structure combining ferrite chip beads and multilayer ceramic chip capacitors.
• Features magnetic shielding using ferrite for excellent attenuation characteristics.
• Designed as a compact surface-mount solution for signal line interference mitigation.

Applications

• Signal line EMI filtering in electronic circuits
• Electromagnetic interference mitigation in compact devices
• High-frequency noise suppression in consumer electronics

Procurement Notes

Verify availability status carefully as this specific part number may be discontinued or subject to limited distribution channels. Confirm exact suffix variations such as TD01 versus TLD01 against official TDK documentation to ensure correct ordering. Check RoHS compliance details directly from the manufacturer datasheet before procurement decisions.

Selection Notes

Select this component when a shielded T-type filter is required for signal lines with low current requirements up to 300 mA. Ensure the 1812 footprint fits the PCB layout constraints. Verify that the 50 V rating meets the circuit's maximum voltage conditions. Consider the 100 MHz cutoff frequency relative to the target noise spectrum for effective attenuation performance.

Part Context

This component belongs to the TDK ACF series, which specializes in magnetically shielded EMI filters. These parts integrate ferrite beads and ceramic capacitors into a single surface-mount package. The series is designed to provide high attenuation in small form factors suitable for modern dense electronic assemblies requiring robust electromagnetic compatibility.
