August 18, 2013
The LPD5030V series from Coilcraft, Cary, IL, offer 1500 VDC (1000 Vrms) winding-to-winding isolation for high-density, isolated circuit applications. The low-profile transformers are 2.9 mm high and measure 4.8 mm square, with a 1:1 turns ratio and a coupling coefficient of K ≥ 0.97; inductance values from 4.7 uH to 220 uH and current ratings to1.9 A. The product can also be used as coupled shielded power inductors in SEPIC converters or as common mode chokes. The model is UL functional safety listed for TNV-1 to SELV applications: functional insulation with a 60 VDC maximum, 42.4 V peak input/output voltages, and working voltages to 210 VDC. It is also RoHS compliant and halogen free.
