Wirewound Resistors, Industrial Power, Miniature Flat (HLM)
FEATURES
• High temperature silicon coating
• Mounting accommodations ideally suited to
high density packaging
• Self-stacking hardware for horizontal or
vertical placement
• Withstands high vibrations without loosening
• Mounting hardware functions as a heat sink
allowing greater heat dissipation and less
derating of stacked units
• Available in non-inductive styles (type NHLM)
with Aryton-Perry winding
• Material categorization:

POWER RATING
Vishay HL flat 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.
D
TERMINAL FINISH
“E” Finish - 100 % Sn coated steel. “Z” Finish - 60/40 Sn/Pb
coated steel. “N” Finish - Nickel coated steel. Finish for
terminal style 16 is limited to nickel plated steel (N).
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 type designation (NHL024, for example). For NHL
models maximum resistance values are lower, see
STANDARD ELECTRICAL SPECIFICATIONS table.
Derating is required for ambient temperatures above 25 °C
per the following graph.
