LOB SERIES
LOW RESISTANCE METAL ELEMENT RESISTOR
• Ultra low resistance values (0.005Ω to 0.1Ω)
• Available in 1-watt, 3-watt and 5-watt rated packages
• Tolerances from ±1% to ±5%
• Inherently non-inductive (≤.02µh @ 0.5MHz)
• Low temperature coefficient of resistance
• High stability over life
• Lead free ROHS compliant construction available
DESCRIPTION:
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.
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
