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 applications. Available in 120- or 200-watt sizes, this resistor is designed for direct mounting onto a heatsink. Popular applications include variable speed drives, power supplies, control devices, telecom, robotics, motor controls, and other switching designs. characteristics Contacts Nickel-plated copper Derating Substrate Al203 (96%) Terminal Nuts American standard 303 stainless steel Resistance Range 0.1 to 1M Tolerance 5%; other tolerances available on request Percent Rated Power Molding Compound High-performance epoxy, compliant to UL94-V0 Temperature coefficient: 250ppm (at +105C ref. to +25C) Max.

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