POWER RATING
Vishay HL flat and HLM resistor wattage ratings are
based on mounting horizontally to 10" x 10" x 0.04"
[254.0 mm x 254.0 mm x 1.02 mm] steel plate in 25 °C
ambient with no air flow.
EXCLUSIVE BRACKET DESIGN
Mounting strap fits snugly through resistor core and is
bound against unit by two eccentric spacers. The bracket
eliminates expensive cements and improves heat transfer
and power handling capabilities.
MATERIAL SPECIFICATIONS
Element:
Copper-nickel alloy of nickel-chrome alloy,
depending on resistance value
Core:
Ceramic, steatite
Coating:
Special high temperature silicone

NHL, NHLM NON-INDUCTIVE
Models of equivalent physical and electrical specifications
are available with non-inductive (Aryton-Perry) winding.
They are identified by adding the letter N to the front of the
HL and HLM type designation (NHLM020, for example). For
NHL and NHLM models maximum resistance values are
lower, see STANDARD ELECTRICAL SPECIFICATIONS
table.
