General Specifications

Electrical Support:
Alumina ceramic metallization with Miba resistor ALTOX film on the bottom for better heat transfer and optimal discharge effects.
Encapsulation:
Resin-filled epoxy resin case with large creepage distance, large electrical clearance between terminals, and high insulation resistance (CTI 600).
Resistance Element:
Specially designed for low inductance and capacitance values. The element uses special METOXFILM, demonstrating stability under high power and pulse loads.
Case:
The case has no color additives. The color is natural and may vary due to different pigmentation.
Connections:
Easily connect loads with M4 and M5 screws (British standard threaded terminals available upon request).
Connector height ranges from 25 to 42 mm.
Various bushings can increase the creepage distance to 85 mm or provide potted cable connections (available upon request).
Standard contacts are M5 (M4 connection screws with a maximum thread of 7 mm available upon request).
