LOBΩ Series power precision metal
element resistors feature resistance
values down to 0.005Ω with virtually
no inductance. Available in 1-, 3- and
5-watt rated axial leaded packages,
these resistors are compatible with
automatic insertion equipment.
DESCRIPTION:
APPLICATIONS:
Switchmode and linear power
supplies.
Automotive current-sensing
circuits
Instrumentation
Regulators
LOBΩ Series resistors feature
tinned copper leads welded directly
to a low-temperature coefficient
resistance element in a highly au-
tomated proprietary process. The
leaded resistor elements are then
encapsulated in a molding com-

ABSOLUTE MAXIMUM RATINGS:
*Power Dissipation - The maximum wattage rating depends upon the amount of heat which can be transferred to the
surroundings while not exceeding the maximum element temperature. Ambient air temperature, velocity of cooling air, thermal
resistance of heat, and the temperature of surrounding objects will affect this transfer, and must be taken into account when
