FB20021-4B-RC Description

Short technical summary and product information.

The Bourns FB20021-4B-RC is a wide-band common mode choke designed for EMI suppression. It features a 2-line configuration with an impedance of 460 Ω at 100 MHz (tolerance ±25%) and 160 Ω at 10 MHz. The component is rated for a continuous current of 5 A with a maximum temperature rise of 20°C. It operates over a temperature range of -40°C to +105°C. The choke is housed in an axial package with 4 leads, suitable for through hole mounting. It is RoHS compliant (with -RC suffix) and carries a California Prop 65 warning. Typical applications include power line filtering and signal line noise suppression.
