UXP300 series Power resistors

Detailed Product Description

UXP300 series Power resistors

Mainly used as a snubber resistor to compensate the C-R peaks in traction power supplies.
General Characteristics
Electric support:High alumina ceramic metallized on the top side with EBG Metoxfilm placed on a solid A1 heat distribution plate for perfect connection to the main heat sink.
Encapsulation:Special resin filled epoxy casing with large creeping distance to mass, large air distance between the terminals and high insulation resistance (CTI 600).
Resistance Element:Special design for perfect current yield over the entire resistor area.
Contacts:Easy load connecting with M4 or M5 screws.
Connector height (M+N) available from 25 to 42mm.Various sleeves for increased creeping
distance up to 85mm or potted cable connections are available on special request.
The model UXP 300 introduced on this page can be changed according to customers
specification.
Please note that almost all of our UXP customers have their own custom designed drawing. Therefore please do not hesitate to discuss your special need with the local representative of EBG.
