SMD Power Inductors - YNR4030 Series
The YNR4030 Series are low-profile, miniature SMD power inductors featuring magnetic shielding and high current saturation. They are designed for applications in small DC/DC converters for devices like HDDs, DVCs, DSCs, PDAs, and LCD displays, as well as car navigation systems, telecom base stations, VR, AR, and LED lighting. These inductors operate within a temperature range of -40 to +125 and are RoHS compliant.
