250W Hybrid Planar Transformers

Vishay Intertechnology, Inc. has introduced a new series of 250W full-bridge hybrid planar transformers for avionics, industrial control, and alternative energy control applications. Featuring a unique winding structure, TPL-2516 series devices provide a cost-effective solution compared to traditional planar transformers while featuring smaller packages, improved performance, and easy customization.

The winding structure of the devices released today allows for a greater copper fill factor than traditional planar transformers, resulting in smaller overall package sizes, a low 16.51 mm maximum profile, and higher power density levels. The unique winding technology also allows the parts to be easily and quickly modified for custom voltage / power applications with no upfront tooling charges to the customer.

Featuring a split primary design for efficient 120V or 380V operation, TPL-2516 series transformers are optimized for offline and PFC-derived switchmode power supplies and full-bridge / half-bridge converters. Designed to meet MIL-PRF-27 requirements, the devices feature overmolded windings for rugged applications and are environmentally sealed for operation in harsh environments.

The TPL-2516 series features operating frequencies from 100kHz to 500kHz, power dissipation of 3W, rated current to 22.0A, leakage inductance down to 1.30µH, and minimal parasitic variation. The devices offer a temperature range of -55 to +130 degrees C, with power derating above +105 degrees C.

Samples and production quantities of the TPL-2516 series are available now, with lead times of eight to 10 weeks. Pricing for U.S. delivery only starts at $7.53 for 500 pieces.
