74275123

Overview

The Würth Elektronik 74275123 is a WE-UKW series EMI suppression ferrite bead featuring a six-hole design. It provides an impedance of 1240 Ohms at 100 MHz with a rated current (IR) of 3A and a resistance of 20mOhm. The component utilizes 4W620 core material, operates within a temperature range of -25°C to +105°C, and supports cable installation for signal line noise reduction.

Feature Summary

• Six-hole geometry enables simultaneous suppression of multiple conductors
• High impedance characteristics effectively attenuate high-frequency electromagnetic interference
• Snap-on construction allows for rapid manual installation on cables

Applications

• Signal line EMI suppression
• Multi-conductor cable noise reduction
• General electronic equipment interference mitigation

Procurement Notes

Verify the specific part number against official Wurth Elektronik documentation to confirm the six-hole configuration and electrical ratings. Ensure compatibility with target cable diameters and operating temperature requirements before procurement.

Selection Notes

Select this component when multi-cable EMI suppression is required in a compact form factor. The three-ampere rating suits moderate current applications, while the high impedance value targets significant noise attenuation needs.

Part Context

This component belongs to the WE-UKW series of snap-on ferrite beads designed for broadband EMI suppression. The six-hole architecture distinguishes it from standard single-hole clamps by accommodating bundled wires or multiple parallel traces simultaneously.
