Features
Extruded aluminium housing provides superior heat conduction.
Housing deep finned for maximum heat dissipation at natural
or forced air convection.
Gold anodized finish for maximum resistance to environmental
conditions.
Special thermosetting compound with high thermal conductivity.
Winding designed to give maximum core coverage and uniformity
for even heat dissipation.
Core centerless ground for maximum
winding uniformity.
Marking at top surface for easy identification after mounting.
Complete welded construction terminal to terminal.
