This listing is for one high-power (30 W) 400 ohm thick film resistor in a TO-220 package, manufactured in Costa Rica for Bourns, Inc.. The resistor has a thermally-conductive alumina ceramic backplane and it will need to be attached to a suitable heatsink depending on use (with no heatsink it is limited to dissipating 2.25 W, continuously).

Tolerance: 5%

Temperature coefficient: 100 ppm/°C

Thermal resistance: 4.2 °C/W

Inductance: <100 nH

Maximum voltage: 2 kV (a higher voltage will produce too much heat)

Operating temperature range: -55 to 150 °C.
