Datasheet

Coilcraft have today announced a new series of miniature flyback transformers, the LPD5030V Series. Providing 1500 Vdc (1000 Vrms) winding-to-winding isolation in the smallest package size available, the compact and low-profile LPD5030V Series transformers have a 1:1 turns ratio and an excellent coupling coefficient of K ≥ 0.97.

Measuring just 2.9 mm in height and 4.8mm in width and length, the compact and low-profile LPD5030V Series transformers are a very cost-effective solution for high-density, isolated circuit applications. The new Coilcraft transformers feature inductance values from 4.7 uH to 220 uH and current ratings to 1.9 Amps. The LPD5030V Series transformers can also be used as coupled shielded power inductors in SEPIC converters or as common mode chokes.

Thanks to its unique design, the LPD5030V Series is UL Functional Safety Listed for TNV-1 to SELV applications. It therefore offers functional insulation with a 60Vdc maximum, 42.4 V peak input/output voltages and working voltages to 210 Vdc. The new transformers are also RoHS compliant and halogen free.
