Pulse Unveils SMT 30W Planar Transformer

November 04, 2001 by Jeff Shepard

Pulse Engineering (San Diego, CA) introduced its new series of low-profile, highly efficient 30W planar transformers, which are a size and weight reduction of up to 60 percent in dc power supplies or in discrete power supply systems, according to the company.

Primary applications for the new transformer series include telecom power systems, industrial control systems or automotive applications where high-package density is required. In addition to their small footprint and low profile (7.4mm), the Pulse 30W planar transformers are claimed to offer significant performance benefits over traditional designs.

"To meet the demands of today's advanced computer and electronic equipment, the transformer must operate at a higher frequency," said Geoffrey Wildman, senior product manager at Pulse. "This introduces significant magnetic design issues, such as high ac losses and leakage inductances, that manufacturers did not face at lower operating frequencies. Pulse planar transformers specifically address these issues with improved magnetic coupling and thermal management for high-energy efficiency."

The operating frequency range is from 150kHz to 750kHz with various turns ratios, and are available to suit a wide range of product applications. The low-profile, surface-mount packaging of these transformers is compatible with all contemporary pick-and-place processes. The operating temperature range is between -40 to +130 degrees C.

Part numbers PA0030T, PA0031T, PA0032T, PA0033T, PA0034T, PA0035T, PA0036T and PA0037T are priced at $3.00 to $3.50 (depending on the turns ratio configuration) for quantities of 10,000.
