steatite ceramic cores or alumina, terminated with welded cap and lead
assemblies and wound with the finest alloy resistance wires welded to the
cap and lead assemblies. Our special formula of vitreous enamel (ALVR)
or silicone (ALSR) coatings are then used to insulate the resistors. This
construction insures long life, durability, and reliability.

RESISTANCE TOLERANCE: Standard tolerance is ±5% (J)
for 1 Ohm, and greater and ±10% (K) for less than 1 ohm.
Available Tolerances: F = ±1%, J = ±5%, K = ±10%
NON-INDUCTIVE: Ayrton-Perry type non-inductive winding is
available. When required add “NI” to the part number.
LEADS: Hot tin-dipped leads with dimensions as shown in the
above chart are standard. However, special lead lengths and
diameters are available. For further infromation please contact
our sales office.
