The Würth Elektronik 74278031 is a flat ferrite core from the WE-FLAT series, designed for cable applications. It is a solid, free-hanging core with a flat profile, making it suitable for use on flat cables or ribbon cables. The core has an outer width of 31.00mm and an outer height of 3.00mm, with an inner width of 27.00mm and an inner height of 0.70mm, accommodating cables up to 26.5mm wide.
Electrically, the core provides an impedance of 21 Ω ±25% at 25 MHz and 52 Ω ±25% at 100 MHz, measured with a 1-turn test cable (AWG26, 50 mm). The material has an initial permeability of 620 typ and a Curie temperature of 150 °C typ. It operates over a temperature range of -25 °C to +125 °C and should be stored below 40 °C and 75% relative humidity.
The core is RoHS compliant, REACH conform, and halogen-free, meeting JEDEC JS709B and IEC 61249-2-21 standards. It is intended for general electronic equipment and is not authorized for use in high-safety or mission-critical applications without specific agreements.
