Low Resistance

Metal Element Resistor

LOB Series

• Low TCR

• High stability over life

• Tolerances from ±1% to ±5%

• Ultra low resistance values (0.005Ω to 0.1Ω)

• Inherently non-inductive (≤.02 µh @ 0.5MHz)

• Available in 1W, 3W, and 5W rated packages

• Lead free RoHS compliant construction available

DESCRIPTION:

The LOBΩ Series power precision metal element resistors feature resistance values down to 0.005 with virtually no inductance.

Available in 1, 3, and 5 watt rated axial leaded packages, these resistors are compatible with automatic insertion equipment.

APPLICATIONS:

• Switchmode and linear power supplies

• Automotive current-sensing circuits

• Instrumentation

• Regulators

CONSTRUCTION:

The 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 molding compound.

*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 selecting a resistor.
