NEW SURFACE-MOUNT, CURRENT-SENSING TRANSFORMERS OFFER VERSATILE, LEAD-FREE CONSTRUCTION
25 July 2003 - Vishay Electronic

Vishay Intertechnology, Inc. today announced the release of the new LPE-3325-CST series of surface-mount, current-sensing transformers featuring five standard turns ratios from 30 to 125 in a lead (Pb)-free construction.

Designed to provide optimal performance at frequencies of 100 kHz and greater, the new LPE-3325-CST is intended for switching power supplies, ac current detection, and output supplies for control circuitry in household appliances and medical and office equipment.

Available with turns ratios of 30, 40, 50, 70, and 125, the transformer released today by Vishay Dale features secondary inductance ranging from 180 µH to 3000 µH at 100 kHz and 0.1 V and a maximum secondary resistance range of 1.00 Ω to 7.70 Ω. All five configurations are rated for 6 A.

Each transformer measures 0.265 in. by 0.323 in. [6.73 mm by 8.20 mm], with a 0.205-in. [5.21-mm] height profile. Custom configurations are available on request. The new devices are specified for an operating temperature range of -40°C to +130°C and are compatible with surface-mount process temperatures.

Samples and production quantities of LPE-3325-CST current-sensing transformers are available now. Lead-time for production quantities is 8 to 10 weeks.
