POWER MAGNETICS
Pulse offers a complete range of magnetics for both high-frequency switching and lowfrequency laminated power supply applications. The switching power magnetics include power inductors, power transformers, current sense magnetics, gate drive transformers and common mode chokes. The laminated power magnetics include both encapsulated and open-frame transformers, as well as ignition transformers for heating and ventilation. For complete product information, please see the "Power Switching Magnetics" or the "Laminated Transformers" catalogs. Pulse also designs and manufactures a wide array of custom and semi-custom magnetics. Contact Pulse Power Applications Engineering for more information. This catalog section serves as an overview to the Pulse Power product line.
NOTE: For additional listings of Pulse Power magnetics, see other Power data sheets at this URL: http://www.pulseeng.com/products/datasheets.aspx.

PRODUCT OVERVIEW: LAMINATED TRANSFORMERS With the addition of encapsulated 50/60 Hz transformers to the existing product line of Pulse open frame transformers, Pulse now offers a complete line of laminated transformers for all your low power, linear transformer requirements. Pulse offers power ratings from 0.08 VA to 175 VA, both fully encapsulated and open frame transformers, and split bobbin designs with a wide variety of domestic and international agency approvals. Pulse is truly the one-stop-shop for all your 50/60 Hz transformer needs. Another new product line in the Pulse family is the Ignition Transformer, used in heating/ventilation applications for gas/oil burners and white goods. The 2003 European RoHS Directive is being applied to Pulse products, indicated by an NL suffix added to the end of the part number for most products. This catalog serves as an overview for the Pulse Laminated Transformers product line. Please contact Pulse Power Applications Engineering by e-mail prodinfo_power@pulseeng.com, for more information.
