SMD Power Inductors - YNR4026 Series
The YNR4026 Series is a line of miniature, low-profile SMD power inductors featuring magnetic shielding and high current saturation capabilities. Designed for demanding applications, these inductors operate reliably in temperatures ranging from -40 to +125 and are RoHS compliant. They are ideal for use in compact DC/DC converters found in devices such as HDDs, DVCs, DSCs, PDAs, and LCD displays, as well as in car navigation systems, telecom base stations, VR, AR, and LED lighting applications.

Note: Saturation current is DC current causing inductance to drop by 30% (at 20). Heat rating current is DC current causing temperature rise up to 40 (at 20). Rated current satisfies both saturation and temperature rise criteria.
