ACF451832-332-TD01

Overview

The ACF451832-332-TD01 is a surface-mount EMI/RFI filter from TDK, designed for signal line applications. It utilizes an LC (T-type) circuit topology with magnetic shielding via ferrite to suppress electromagnetic interference. The component operates within a frequency range of 35 MHz to 100 MHz, providing attenuation of 25 dB in this band. It features a current rating of 300 mA and a voltage rating of 50 V. The device is housed in an 1812 (4532 metric) package with SMD/SMT termination, suitable for automated assembly processes.

Procurement Notes

Verify the specific suffix TD01 against official TDK documentation to confirm packaging and handling specifications. Ensure compatibility with existing PCB footprints and reflow soldering profiles. Confirm availability status as distribution channels may vary. Cross-reference part numbers with authorized distributors to avoid counterfeit components. Check RoHS compliance details if required by regulatory standards.

Selection Notes

Select this component when high attenuation is required in the 35-100 MHz range for signal lines. Consider the 300 mA current rating and 50 V voltage limit for circuit integration. The 1812 package size offers a balance between performance and board space. Evaluate thermal requirements and operating temperature range (-25°C to +85°C) for the specific application environment.

Part Context

This component belongs to the TDK ACF series of EMI/RFI filters. The series is characterized by superior attenuation characteristics achieved through magnetically shielded T-type filter circuits. These filters are engineered for compact designs requiring effective noise suppression in sensitive electronic systems.

Replacement Considerations

Consult TDK's official substitution guide or contact technical support for verified alternative part numbers. Do not assume cross-compatibility with other manufacturers' components without rigorous testing and datasheet comparison.
