SKOKIE, ILL. Noninductive, bulk ceramic resistors from 2.5 to 5.5 W with resistance values from 1 to 15,000 ohms in 10 percent tolerance are available from Ohmite Manufacturing Co.
Designed for applications that require high energy-handling capabilities, the resistors have Joule ratings beginning at 400 for 2.5-W devices and 2,800 for 5.5-W parts. The predictable thermal response is said to provide design advantages over current-limiting devices with nonlinear responses to changes in temperature. Prices in quantities of 50 range from $7 to $12.
