tGh series 120 and 200 Watt SOT227Package Thick Film Power Due to their non-inductive design, these resistors are ideally suited for high-frequency and pulse-load applica- tions. Available in 120- or 200-watt sizes, this resistor is designed for direct mounting onto a heatsink. Popular applications include variable speed drives, power sup- plies, control devices, telecom, robotics, motor controls, and other switching designs. characteristics Nickel-plated copper Heat Sink Derating Contacts Nickel-plated copper Type: H L Substrate Al203 (96%) 100 120 200 Molding Compound High-performance epoxy, compliant to UL94-V0 80 96 160 Terminal Nuts American standard 303 stainless steel 60 72 120 0.1 to 1M 40 48 80 Resistance Range 20 24 40 Tolerance 5% other tolerances available on request 0 0 0 Temperature coefficient: 250ppm (at +105C ref. to +25C) 0 2550 85100 125 150 175 Bottom of base plate Temperature, C Max.

Maximum base plate temperature of the resistor must be monitored and kept within specified limits to es- tablish the power rating. Best technique is to attach a thermocouple to the side of the base plate of the resis- tor. Temperature of plastic housing or heat sink cannot be used to establish rating of the resistor. 1-866-9-OHMITE Intl 1-847-258-0300 Fax 1-847-574-7522 www.ohmite.com info ohmite.com 155
