Rolling Meadows, Ill. Ohmite Manufacturing Company has introduced two new families of four-terminal bare element resistors. The new 610 and 650 Series devices provide ultra-low resistance values to 0.005 ohms for relatively high-current requirements. Together with a radial Kelvin configuration and PC-board mounting, this makes the new devices suitable for current sense applications.
The 610 and 650 devices feature a power rating of 1 watt and 5 watts, respectively. Both series feature a 1% tolerance standard, low inductance below 0.25 ohms, tinned copper leads, and RoHS compliance.
In addition, these resistors offer an overload capability of five times their rated wattage for 5 seconds, and high power-to-size ratio. The operating temperature is -55°C to 275°C. Devices also exceed the requirements of MIL-PRF-49465.
Pricing ranges from $3.65 to $4.48 each in quantities of 500.
