ACF321825-103-TD01

Overview

The TDK ACF321825-103-TD01 is a surface-mount EMI filter circuit designed for signal line protection. It utilizes an LC (T-type) topology with ferrite magnetic shielding to provide high attenuation in the 17 MHz to 60 MHz frequency range, achieving 25 dB suppression. The component operates within a -25°C to +85°C temperature range and supports a maximum current of 300 mA at 20 V. Housed in a compact 1210 (3225 metric) package measuring 3.2 mm x 2.5 mm x 2 mm, it is suitable for mobile device data lines.

Feature Summary

• Magnetic shielding using ferrite material enhances attenuation performance
• LC (T-type) circuit topology for effective EMI suppression
• Compact 1210 surface-mount footprint for space-constrained designs

Applications

• Mobile device data lines
• Signal line EMI filtering
• High-frequency noise suppression in portable electronics

Procurement Notes

Verify component status as this part may be discontinued or subject to production change notices. Confirm availability through authorized distributors and check for recommended replacements if necessary. Ensure compliance with RoHS3 specifications and validate lead times for alternative sources due to potential supply constraints.

Selection Notes

Select this component when specific attenuation in the 17-60 MHz range is required for signal integrity. Consider the 300 mA current rating and 20 V voltage limit against circuit requirements. The 1210 package size dictates board layout constraints. Verify thermal operating limits align with the application environment.

Part Context
