H.E.I. Standard Oval Wirewound Resistors are ideally suited for applications

where high power dissipation is desired in a small area. A thin oval cross sec-

tion and flat mounting brackets allow stacking into compact units. The metal

mounting brackets extend through the resistor core and equalize heat distribu-

tion while conducting heat directly into the mounting suface.

V=VITREOUS

S=SILICON

RESISTANCE TOLERANCE: Standard tolerance is ±5% for 1 ohm and greater and

±10% for less than 1 ohm. Available Tolerances: F = ±1%, J = ±5%, K = ±10%

MOUNTING BRACKETS: Constructed of plated steel and aluminum standoffs and are

an integral part of the resistor.

TEMPERATURE COEFFICIENT: ±400 PPM/8C 1Ω to 20Ω, ±260 PPM/8C 20Ω and

above. (Special TC’s are availalbe, consult factory.)

NON-INDUCTIVE: Ayrton-Perry type non-inductive winding is available. When required

add “NI” to the part number.

DIELECTRIC WITHSTANDING VOLTAGE: 1000 VAC measured from terminals to

mounting brackets.

OVERLOAD: 10 X rated wattage for 5 seconds.

TERMINALS: Hot tin dipped are standard.

COATING: Available in Vitreous Enamel or Silicone.

CORE: Steatite ceramic.
