74275043 Description

Short technical summary and product information.

The Würth Elektronik 74275043 is a single-line EMI suppression ferrite bead from the WE-UKW series. It offers a typical impedance of 961 Ω at 100 MHz and 920 Ω at 25 MHz, with a ±25% tolerance. The component is rated for a maximum continuous current of 3 A (ΔT = 40 K) and has a maximum DC resistance of 20 mΩ.

 

This ferrite bead is designed for through-hole mounting in a radial package with a 6.00 mm body diameter and a maximum height of 10.00 mm. It operates over a temperature range of -55°C to +125°C and has a Curie temperature of 175°C. The component is RoHS compliant, REACH conform, and halogen free.

 

Typical applications include power supply filtering, DC/DC converter noise suppression, and general EMI attenuation in electronic circuits. The radial lead form factor is suitable for board-level installation where surface-mount components are not preferred.
