The CF5W-470K-J-T52 Carbon Film Resistors 470K Ohms ±5% 5W Axial RoHS, from Chian Chia, are axial resistors made from a carbon film composed of a carbon/polyester film with nickel chromium alloyed resistive film. They have an operating temperature range between -55 to +155 degrees Celsius, and they come with an insulation resistance of 100 Megaohms or more. The resistors provide an allowable power dissipation of 5W (at 55 degrees Celsius) and a voltage proof from Terminator to Resistor of 500V. The type of resistance element in these resistors makes it ideal for applications that involve repetitive motion switching. The tolerance level of these resistors is +/- 5%, with a maximum reverse voltage of 200V. These resistors are RoHS compliant, having passed a number of testing standards.
