ACF451832-151-TD01

Overview

The TDK ACF451832-151-TD01 is a signal line EMI filter circuit designed for surface mount applications. It operates within a voltage range of 50 V and supports a current rating of 300 mA. The component features an LC (T) filter topology with a cutoff frequency of 100 MHz. It is housed in an 1812 (4532 metric) package, suitable for vertical mounting to conserve board space. The device functions reliably across an operating temperature range from -25°C to 85°C.

Feature Summary

• Integrates ferrite chip beads and multilayer ceramic capacitors into a single T-type EMC filter structure
• Vertical mounting design minimizes footprint requirements for high-density circuit layouts
• Compatible with standard reflow soldering processes for automated assembly

Applications

• Signal line EMI suppression in compact electronic devices
• High-density PCB designs requiring minimal mounting space
• Surface mount assembly for consumer electronics

Procurement Notes

This component is classified as obsolete or last-time buy status by the manufacturer. Availability is strictly limited to remaining stock held by distributors. Verify RoHS compliance and lead times directly with suppliers before ordering, as production has ceased. No new manufacturing units are expected.

Selection Notes

Select this part for applications requiring a compact, vertically mounted EMI filter with specific 100 MHz cutoff characteristics. Ensure the design accommodates the 1812 package dimensions and 300 mA current limit. Consider alternative active components if long-term supply stability is required, given the obsolete status.

Part Context

Part of the TDK ACF series, which combines passive components for efficient noise reduction. The series is engineered for SMT processes and vertical integration. This specific model represents a fixed-value solution within the broader family of signal line filters offered by TDK for electromagnetic compatibility.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation due to the obsolete status. Engineers should consult TDK technical support or authorized distributors for validated cross-references that match the electrical and mechanical specifications.
