FVOT / FSOT
STANDARD OVAL
WIREWOUND RESISTORS
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.

ENGINEERING AND MATERIAL DATA
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.
