ACF451832-102-TD01

Overview

The ACF451832-102-TD01 is a signal line EMI filter from TDK Corporation, classified as an LC (T) network. It features a voltage rating of 50 V and a current rating of 300 mA. The component utilizes SMD/SMT termination styles within an 1812 (4532 metric) package. Its cutoff frequency is specified at 90 MHz, with an operating temperature range spanning from -25°C to 85°C.

Feature Summary

• Integrates ferrite chip beads and multilayer ceramic capacitors for EMC filtering
• Designed as a low-pass filter for signal line protection
• Utilizes surface mount technology for compact circuit board integration

Applications

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

Procurement Notes

Verify the specific suffix TD01 against official TDK documentation to confirm exact electrical characteristics and physical dimensions. Confirm availability status as distribution channels may list this part as obsolete or last-time buy. Ensure compatibility with existing PCB footprints before ordering.

Selection Notes

Select this component when a 50 V rated, 300 mA capable EMI filter is required for high-frequency noise suppression. The 1812 package size suits space-constrained designs. Verify that the 90 MHz cutoff frequency aligns with the target signal bandwidth requirements for effective interference reduction.

Part Context

This model belongs to the TDK ACF series, which combines ferrite beads with ceramic capacitors in a single surface-mount package. The series provides integrated solutions for electromagnetic compatibility issues in compact electronic devices, replacing discrete component arrangements.

Replacement Considerations

Consult official TDK substitution guides for verified equivalents. Cross-reference pinouts and impedance curves with alternative LC filters from other manufacturers if direct replacement is unavailable.
