Surface Mount Power Standard pedestal mount Recessed-base mount RC Series: carbon composition (1/4 & 1/2 watt) RC Series: ceramic composition (above 1/2 watt) RF Series: metal film RW Series: wirewound RP Series: power film RM Series: high voltage thick film Flexible J-bend • Tolerance 1%, 5%, 10%, depending on construction • Twelve wattage ratings • Seven package sizes • Two mounting designs to accommodate your soldering process • Five power resistor technologies to optimize your operating performance: 1. Carbon and Ceramic composition for surge and low inductance 2. Metal film for high ohmic value and low T.C. 3. Wire element for inrush current combined with low ohmic values. Resistance values as low as 0.005Ω 4. Power film for high ohmic value and high wattage 5. High Voltage thick film for high voltage applications • Flexible J-bend terminations • Working Temperature Range: -55°C to +150°C S ER I E S S P E C I F I C AT I O N S Military grade versions available; contact Ohmite. *Last two digits designate package size Wirewound Surface mount 1-866-9-OHMITE • Int’l 1-847-258-0300 • Fax 1-847-574-7522 • www.ohmite.com • info@ohmite.com
