Common Mode Chokes datasheet and documents for HF2018R-253Y0R4-01

HF2018R-253Y0R4-01

Common Mode Chokes Overview

The HF2018R-253Y0R4-01 is a two-line common mode choke manufactured by TDK Corporation. It features a vertical through-hole package with four PC pins. The component is rated for a maximum current of 400mA and has a DC resistance of 2.9 Ohms. It provides effective filtering at 25MHz, making it suitable for suppressing electromagnetic interference in low-current signal lines.

Common Mode Chokes Feature Summary

Provides common mode noise suppression for two-line circuits
Designed for through-hole mounting on printed circuit boards
Utilizes ferrite material for high-frequency attenuation

Common Mode Chokes Applications

Signal line filtering in consumer electronics
Noise suppression in data communication interfaces
EMI reduction in industrial control systems

Common Mode Chokes Procurement Notes

Verify the specific suffix '01' to ensure correct packaging and tape configuration. Confirm that the 400mA rating meets the operational requirements of the target circuit. Check for end-of-life status as some sources indicate discontinuation. Ensure compatibility with existing PCB footprints requiring vertical 4-pin through-hole components.

Common Mode Chokes Selection Notes

Select this component when low current handling up to 400mA is sufficient. Consider the 2.9 Ohm DC resistance impact on signal integrity. Evaluate the 25MHz filtering characteristic against the noise spectrum. Compare physical dimensions against available board space for vertical mounting.

Common Mode Chokes Part Context

This part belongs to TDK's HF series of common mode chokes. These components are designed for general-purpose EMI suppression. The series offers various current ratings and impedance characteristics. TDK utilizes proprietary ferrite materials to achieve stable performance across temperature ranges.
