 Miniature Power

MRB Resistors

In comparison to the standard MRP series, from 1.5 to 4 times rated power for equivalent size

The standard core material is alumina which provides a significantly broader heat dissipation pattern than a ceramic core.

Special temperature coefficients available.precdwg.gif (5649 bytes)

Meets or exceeds the specifications in MIL-R-26E for wirewound resistors.

Meets the applicable specifications of MIL-STD-202, method 208

CORE: Alumina ceramic

ELEMENT: Typically a nickel-chrome alloy. May be a copper-nickel alloy at very low resistances.

END CAPS: Stainless Steel

LEADS: Tinned Copperweld typical. Tinned Copper and Nickel available on some sizes.
