Resistors have very low resistance
Ideal for many current monitoring and precision control applications, Ohmite’s new TGHG Series SOT-227 type resistors are available in resistance values as low as 0.0005 ohms. The non inductive, thick film power resistors, when used with the appropriate heatsink, are equally suited to high power current monitoring up to100W. Providing highly reliable, non inductive performance the TGHG features a four terminal Kelvin connection to isolate measurement path from current flow path.
The resistor has a nickel-plated copper heatsink, standard resistance values of 0.5m ohm to 1 ohm, while others are available on request. With resistance tolerances of 1%, the component can handle a pulse current up to 500A/0.5sec, depending on ohmic values.
Power rated at 100W at 70°C case temperature, 50Amp permanent, the dielectric strength of the TGHG is 1000VDC. Higher values can be obtained With heat resistance of Rth <0.56K/W, the RoHS compliant device has protection to IEC 950/CSA22.2 950/M -89 and EN 60950.88:2. The ambient operating temperature is -55°C to +155°C.
