ACF321825-680-TD01

Overview

The ACF321825-680-TD01 is a signal line EMI filter from the TDK ACF series. It utilizes LC (T-type) technology to provide low-pass filtering for data lines. The component features a single channel with a rated voltage of 20V and a maximum current rating of 300mA. It operates within a temperature range of -25°C to +85°C. The device is housed in a surface-mount 1210 package, measuring 3.20mm x 2.50mm x 1.8mm.

Feature Summary

• Integrates EMI noise suppression capabilities within a compact surface-mount footprint.
• Employs LC T-type circuit topology for effective signal line filtering.
• Designed specifically for protecting data lines in mobile devices.

Applications

• Mobile device data lines
• Signal line EMI filtering
• Embedded system data interfaces

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for specific packaging variations such as tape and reel quantities. Ensure the part number suffix matches required specifications before procurement.

Selection Notes

Select this component for applications requiring low-profile EMI suppression on high-speed data lines. Consider the 300mA current limit and 20V rating when designing power and signal integrity paths. Verify that the 1210 package dimensions fit the available PCB real estate constraints.

Part Context

This component belongs to the TDK ACF series of micro-filters. These filters are engineered to combine ESD protection and noise suppression into a single small package. The series targets space-constrained portable electronics where multiple protection functions are required without increasing board area.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Consult official TDK resources for cross-reference information regarding equivalent LC T-type filters with similar electrical ratings.
