Riedon, Inc. Through Hole Resistors PF2205-91RF1

The PF2205-91RF1 is a TO-220 power thick film resistor designed for high stability and reliability in various applications. It has a rated power of 50 watts when mounted on a heatsink, with a maximum operating voltage of 500V. The resistance range spans from 0.02 to 51K ohms, with a tolerance of ¬±1% and a temperature coefficient of resistance (TCR) of ¬±50ppm/¬8C for resistances greater than or equal to 10 ohms. The resistor features a non-inductive design with inductance less than 10nH, making it suitable for high-frequency applications. The operating temperature range is from -55¬8C to +175¬8C, and it exhibits moisture resistance and a dielectric strength of 2000 VAC. The PF2205-91RF1 is also designed for durability, with specifications for load life, humidity resistance, and temperature cycling, ensuring consistent performance under various environmental conditions. The mounting tab is isolated from both pins, and the resistor must be attached to a suitable heatsink for optimal performance.
