Bourns RLB1112V4 400V Radial Inductors

Bourns RLB1112V4 400V Radial Inductors are 400VDC rated, non-shielded inductors with a radial-lead construction and 5mm fixed lead spacing. The RLB1112V4 devices offer an inductance range of 1.0mH to 4.7mH with a ±5% tolerance. These inductors are covered with shrink tubing to provide physical protection, as well as electrical insulation to the component.

The RLB1112V4 inductors are RoHS compliant and designed for use with TI's UCC28880 Converter. Additional applications include DC/DC converters and power supplies. The RLB1112V4 components are ideal for 85VAC to 265VAC AC-to-DC power supplies with applications in metering, home automation, infrastructure SMPS, TRIAC drivers, appliances, white goods, and LED drivers.
