Pulse Unveils Industry's Smallest SMT 30-Watt Planar Transformer
Pulse Planar Transformers Reduce Cost and Board Space Up To 60%

SAN DIEGO--(BUSINESS WIRE)--Oct. 30, 2001--In this age of high-density integration of electronic devices, smaller and thinner transformers are becoming indispensable.
Pulse is meeting this need with the introduction of a new series of low-profile, highly efficient 30-watt planar transformers.
A major benefit of the new Pulse 30-watt planar transformers is a size and weight reduction of up to 60 percent in DC power supplies or in discrete power supply systems. Pulse planar technology involves multi-layer Printed Circuit Boards (PCBs), sandwiched between ferrite cores to make small, flat components ideally suited to PCB mounting.
Primary applications for the new transformer series include telecom power systems, industrial control systems, or automotive and heavy equipment applications where high-package density is required. In addition to their small footprint and low profile (7.4mm), Pulse 30-watt planar transformers 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. With their superior electromagnetic compatibility, EMC compliance is easily achieved and the operating temperature range is between -40 degrees C to +130 degrees C.
Pricing and Availability
Part numbers PA0030T, PA0031T, PA0032T, PA0033T, PA0034T, PA0035T, PA0036T and PA0037T are priced at $3 to $3.50 (depending on turns ratio configuration) for quantities of 10,000.
