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.

Applications for the Ohmite TAP2000 Heat Sinkable Planar 2000W Resistors are power conditioning, power distribution, power conversion, power control, power semiconductor balancing, motor control, and inrush current limiting.
Ohmite SH Series Precision Metal-Clad Shunts
The Ohmite SH Series Precision Metal-Clad Shunts are designed with a simple four-terminal Kelvin design to ensure easy installation on large current bus bars. The SH Series resistors are distinguished by high load capacity as well as excellent accuracy. Isolated voltage and current connections make them suitable for very precise current connection measurements for battery testing, current detection in precise power sources, constant current sources, industrial power conversion circuits, HEVs, fuel cells, and constant electronic loads. The Ohmite SH Series Precision Metal-Clad Shunts offer low inductance and heavy copper terminals.
Ohmite TGHG Series Precision Current Sense Resistors
Introduced by Mouser in January 2009, the Ohmite TGHG Series Precision Current Sense Resistors
use state of the art technology to provide highly reliable,
non-inductive performance. With resistance values beginning at 0.5mΩ,
the TGHG series features a four terminal Kelvin connection in an SOT 227 package. Ohmite's TGHG Precision Current Sense Resistors
use the four terminals to isolate the measurement path from the current
flow path and provides accuracy in a high power package.
Ohmite FCSL Series Metal Foil Current Sense Resistors-EXPANSION
Ohmite has expanded its FCSL Series Metal Foil Current Sense Resistors to include 5 Watt
power ratings sizes. In addition, side and back electrodes have been
added to ensure better solder joint attachment and easier inspection.
