Maximum storage temperature

* 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, this must be taken

into account when selecting a resistor.

Description

Construction

LOBΩ Series power precision metal element resistors feature

resistance values down to ±.±±0Ω with virtually no

inductance. Available in 1, ꢀ and 0 watt rated axial leaded

packages, these resistors are compatible with automatic

insertion equipment.

LOBΩ Series resistors feature tinned copper leads welded

directly to a low temperature coefficient resistance element in

a highly automated proprietary process. The leaded resistor

elements are then encapsulated in a moulding compound.

Applications

Switchmode and linear power supplies.

•

Automotive current-sensing circuits.

Instrumentation.
