All Ohmite S Series High Current Shunts are calibrated to 0.50% tolerance and have a 0.5% accuracy class. Ideal for green energy applications.
Ohmite M Series Dual Clip Heatsinks for TO-264 and TO-247 EXPANSION
The Ohmite M Series Dual Clip Heatsinks for TO-264 and TO-247 packages. The M Series is a patented, high performance, low cost, configurable, scalable, and compact heat sink with a matrix clip system. This powerful heat sink provides the easiest assembly, largest surface area, and smallest footprint. The Ohmite M Series Dual Clip Heatsinks for TO-264 and To-247 are the ideal type of heat sink for high power density and small size (1U or 2U) electronic packaging with force convection cooling.
Ohmite A Series Ceramic Composite Resistors
The Ohmite A Series Ceramic Composite Resistors' unique design allows uniform distribution of energy throughout their structure which results in low thermal stress, and features high surge energy and small size. The high-temperature, solvent-resistant epoxy coating carries a UL94V0 flammability rating which is suitable for almost any environment, such as motor drives, power supplies and power conversion. The Ohmite A Series Ceramic Composite Resistors are ideal for any application which is subject to surges, high peak power, or impulse energy.

Ohmite Assorted Resistor Cabinet Kits
Ohmite's assorted Resistor Cabinet Kits conveniently house a variety of popular resistor products in sturdy, wall-mountable steel cabinets. Each cabinet of the resistor kit from Ohmite contains 20 clear plastic drawers that can be subdivided by 2, making a total of 40 slots available. In addition, removing the latched front cover reveals an easy reference key that describes the contents of each drawer. One kit, the CAB-20, doesn't contain any products, but plastic vials that are usable for any parts that fit in the 6" deep x 3" wide x 2" tall drawers. Types of products housed in these cabinets are current sense resistors, power resistors, and heatsinks.
Ohmite FC4L Series 4-Terminal Current Sense SMD Resistors (Foil Type)
Ohmite has extended its FCSL Series product line with the 4-terminal, foil-type FC4L Series Current Sense SMD Resistors. The FC4L Series resistors from Ohmite have a foil construction that ensures a very stable TCR (Temperature Coefficient of Resistance) in a 5 watt package. In addition, FC4L resistors have a built-in Kelvin connection and 4-terminal design, which includes 2 larger electrodes capable of carrying large currents and 2 smaller electrodes for current measurement.
Ohmite S Series LED Heatsinks
Ohmite S Series LED Heatsinks are low cost and easy assembly heat sinks for "Star" LED packages supplied by Osram and others. This simple heat sink can hold LED modules and can be mounted simply with some thread forming screws. The Ohmite S Series LED Heat Sinks have two types of surface finish and can be used in either natural (free) or forced convection cooling applications.
