The OHMITE MANUFACTURINGTN15P300RFE is a high-performance thin film resistor designed for through-hole mounting in power applications. This resistor features a 15-watt power rating and a resistance value of 300 ohms, making it suitable for current sensing and high-precision circuits.
Constructed with advanced thin film technology, this resistor offers several key performance advantages:
Extremely stable with low Temperature Coefficient of Resistance (TCR)
Low noise due to parasitic capacitance and resistance
15W (heat-sink dependent; must be attached to proper heat sink)
Resistance Range
4Ω - 10KΩ
Resistance Tolerance
1%, 2%, 5%
Max Working Voltage
150V (3KΩ-10KΩ), √15*R (4Ω-1KΩ)
Max Working Current
√20/R (0.3Ω-10KΩ), 10A (0.01Ω-0.1Ω)
Thermal Resistance (RTH)
<8.33°C/W
Maximum Case Temperature
150°C
Physical Dimensions
Diameter: 0.177" (4.57mm)
Width: 0.394" (10mm)
Height: 0.591" (15mm)
Mounting Hole Diameter: 6-32 tapped screw
Additional Information
This product is designed for use with proper heatsinking. The maximum base plate temperature must be monitored to ensure safe operation. Attach a thermocouple to the side of the resistor's base plate for accurate temperature measurement. The plastic housing or heat sink temperature alone cannot be used to determine the resistor's rating.
Note: This product has been discontinued as of May 2013. Available stock is limited. For more details, please refer to the datasheet.
