LVK Series Resistors - Ohmite's surface mount LVK current sense resistor series are available in sizes 1206, 2010 and 2412, with an alternate 2W version in a 1224 footprint. The LVK chip features a four terminal Kelvin configuration that enables current to be applied through two opposite terminals and a sensing voltage to be measured across the other two terminals, eliminating the resistance and temperature coefficient of the terminals for a more accurate current measurement. Isolating the voltage and current terminals facilitates an accurate current measurement. Ohmite's proprietary technology offers an excellent Temperature Coefficient of Resistance (TCR) even for very low resistance values. The resistive element consists of a durable, anti-corrosive metal alloy that combines reliable performance with the ability to withstand harsh environments. More...

WV Series Heatsinks - Ohmite has launched a series of heatsink solutions for use with the popular TO-220 and TO-247 power resistors or similarly packaged semiconductors. These self aligning heatsinks feature solderable feet for through-hole placement and an integrated clip, which provides 13.2 lbf of force on the center of the resistor, enhancing thermal performance and reducing parts count and assembly time. The major advantages of this design are the reduced cost and labor. The spring clips make mounting holes, screws and fasteners obsolete in the assembly process. The spring coil also provides superior performance under shock and vibration. Light weight and resilient, the spring clip can absorb energy as it locks the electronic component in place. Since no screw hole needs to be tapped, stray metal particles are eliminated along with the possibility of an accidental short circuit resulting from their presence. More...
