74279271 Description

Short technical summary and product information.

The 74279271 from Würth Elektronik is a surface-mount ferrite bead designed for EMI suppression in signal lines. It features an impedance of 120 Ω ±25% at 100 MHz, with a maximum impedance of 200 Ω typ. at 600 MHz. The component is rated for a continuous current of 500 mA at ΔT=20 K, and up to 1100 mA at ΔT=40 K, with a maximum DC resistance of 200 mΩ.

 

Engineered for wide-band/high-speed applications, this ferrite bead is housed in a compact 0402 (1005 Metric) package with dimensions of 1.00 mm x 0.50 mm and a maximum height of 0.55 mm. It supports an operating temperature range of -55°C to +125°C and is qualified to AEC-Q200 Grade 1 for automotive reliability.

 

The component is RoHS compliant, REACH conform, halogen-free, and has a Moisture Sensitivity Level (MSL) of 1. It is suitable for use in automotive electronics, high-speed data lines, and general-purpose EMI filtering where board space is limited.
