Ohmite has maintained a leadership position in the design and manufacture of Power Resistive Products since 1925. Through innovation and acquisition Ohmite's offering has grown to include power resistors, surface mount resistors, and rheostats. Ohmite will continue to develop new technologies and packaging techniques to meet the demand of the changing market far into the future.
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.
NEW! Ohmite has expanded the FC4L Series to now include a 2-watt package size (6.4 x 3.2mm).
Ohmite's HVC Series Thick Film Resistors are high-value, high-voltage wraparound chip resistors in thick film technology. The HVC Series resistors from Ohmite feature low temperature and voltage dependency (low TCR and VCR), high working voltage up to 3000V, and RoHS compliance. Available case sizes are 0805, 1206, and 2512.
Ohmite's SV-LED Series Heat Sinks are high performance, low cost, configurable, scalable and compact power heatsink for LED modules. These powerful, high aspect ratio heatsinks come in two standard heights (14 and 25mm). They can be configured to customer specifications for length, surface finish, mounting holes, and custom machining. With a 9.9mm mounting surface, these heatsinks are popular in applications such as illuminated headsets for surgeons and dentists.
Ohmite D Series Heatsinks have been expanded with two new extrusion forms. The new extrusions do not require the use of Kapton Tape to facilitate pick-and-place equipment.
Ohmite D Series Heatsinks for SMT compatible semiconductors and resistors combine tin plated, solderable rods with an aluminum extruded heat sink body. These rod (rollers) are mated mechanically to the heatsink by forging to reduce the thermal resistance between the heatsink body and the solderable feet. With increased thermal performance up to 30% over bright copper heat sinks, the Ohmite D Series Heatsinks are designed for use with the popular TO-263 and TO-268 packages and the light weight aluminum construction allows faster pick and place assembly.
Ohmite CP4 Series Heat Sinks are designed for Ohmite heatsinkable type resistors, such as TAP600, TAP800, TA1K0, TA2K0, and various SOT-227 resistor packages. The CP series also provides maximum heat removal for SCRs, rectifiers, diodes, thyristors, and other high-power semiconductor devices. Ohmite CP4 Series Heat Sinks are customizable to fit multiple applications. Length and mounting hole patterns can be specified.
Ohmite W Series Heatsinks for Power Resistors has been expanded. New are sizes available.
The Ohmite Heatsinks, W Series, are for TO-220 and TO-247 Power Resistor or similarly packaged semiconductors. These self-aligning Ohmite W series heatsinks feature
solderable feet for through-hole placement, and an integrated clip
which provides 1.32 (lbf) of force on the center of the resistor, enhancing thermal performance and reducing parts count and assembly time.
Ohmite R2 Series Heatsinks have been expanded. New sizes available! Learn more.
Ohmite R2 Series Heatsinks feature reduced assembly cost due to camming clips, maximum repeatability, and maximum reliability. Ohmite R2 Series Heatsinks' maximum surface area per unit volume and consistent mounting force reduces thermal resistance. Light weight, resilient clips lock R2 Series Heatsinks in place, making them highly resistant to shock and vibration. The C Series clipping mechanism provides a large surface area for the Ohmite R2 Series Heatsinks to attach either a TO-220 or TO-247 package. View the entire R2 Series.
M Series Dual Clip Heatsinks has been expanded. New sizes available!
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. View the entire M Series.
Ohmite offers new mini 3 and 5 Watt precision WH/WN Series Wirewound Resistors. These WH/WN Series Wirewound Resistors feature a resistance range of .10 - 50 K, are encapsulated by epoxy molding compound, and are designed to meet MIL-R-26F and MIL-STD-202 standard requirements. These resistors are ideal for precision applications where costs are sensitive, such as office and lab environments.
Ohmite C Series Heatsinks have been expanded; TO-220 and TO-64 versions are now available.
Ohmite C Series Heatsinks
offer high performance, low cost and is a compact heat sink with an
integrated camming clip system.These powerful heat sinks provide tool and fixture free assembly operation, largest surface areas and smallest space occupation. The Ohmite C Series Heatsinks are the ideal type of heat sink for high power density and small size (1U or 2U) electronic packaging with forced convention cooling, such as semiconductors and resistors.
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.
