74270090 Description

Short technical summary and product information.

This Würth Elektronik 74270090 is a solid round ferrite core designed for EMI suppression on cables. It provides a typical impedance of 250 Ohm at 100 MHz with a single turn, and 155 Ohm at 25 MHz with two turns, using AWG26 test wire. The core is made from 4W620 ferrite material with a Curie temperature of +150°C.

 

Mechanical dimensions include an outer diameter of 26.00 mm, inner diameter of 13.00 mm, and length of 28.50 mm. The mounting type is free hanging, suitable for cable diameters up to 13 mm. The operating temperature range is -25°C to +85°C, with storage temperature from -55°C to +85°C.

 

Electrical specifications are based on typical test conditions. The component is listed as RoHS3 compliant, REACH unaffected, and MSL 1 (unlimited), though these compliance statuses are unverified and should be confirmed with the manufacturer.
