742861118 Description

Short technical summary and product information.

The Würth Elektronik 742861118 is a WE-CBF HF series SMT EMI suppression ferrite bead designed for high-frequency signal line filtering. It provides a nominal impedance of 180 Ω at 100 MHz with ±25% tolerance, and a typical impedance of 180 Ω at 1 GHz. The maximum impedance reaches 300 Ω typical at 450 MHz.

 

This single-line ferrite bead is rated for a maximum current of 200 mA with a 20 K temperature rise, and 700 mA with a 40 K rise. DC resistance is 0.25 Ω typical and 0.55 Ω maximum. The component operates over a temperature range of -55°C to +125°C.

 

The device is housed in a standard 0603 (1608 metric) surface-mount package with dimensions of 1.60 mm length, 0.80 mm width, and a maximum height of 0.95 mm. It is compliant with RoHS, REACH, and halogen-free standards, and has a Moisture Sensitivity Level (MSL) of 1.
