Ohmite has been the leading provider of resistive products for high current, high voltage, and high energy applications for over 90 years. The company’s full complement of resistor construction includes wirewound, wire element, thick film, and ceramic composition. Ohmite also leads the way in thermal management for resistive and other technologies offering a vast array of heatsinks.
New Ohmite Products
ALN Series Thick Film High Power Chip Resistor
Ohmite has the solution for high wattage surface mount chips. The ALN series thick film chips offer 3.5 watts of power dissipation in a 2512 package size. This is accomplished with the use of an Aluminum Nitride substrate. Aluminum Nitride (AlNi) dissipates heat far more efficiently than standard Alumina or Ceramic substrates. Ohmite has engineered a thick film printing process to apply a resistive ink to the AlNi substrate creating an optimal chip for high power. Temperature coefficients are down to 150 ppm providing a chip with great stability.
Ohmite now carries a line of heatsink solutions that are specifically designed for your BGA and PBGA applications. Ohmite’s heatsinks provide a low-cost thermal solution for these specific packages in multiple sizes. Our heatsink solutions can be attached to devices with adhesive thermal tape, making installation as seamless as possible. Custom heatsinks are available upon request.
PCS Series Low Resistance Value Chip Resistors
Available in three sizes (1206, 2512, and 2728) the PCS Series offers low resistance values to 0.50mΩ. This product provides users with high precision current sensing and voltage division. It also offers low TCR to ±50ppm, excellent long-term stability, and RoHS compliance.
FK/GK Series RoHS Compliant Metal Element Kelvin Resistor
Ohmite’s FK/GK Series is a low-resistance, 4-terminal element resistor with a power rating up to 5W. This product offers excellent long-term stability and is ideal for mounting on DCB/IMS substrates. Ohmite recommends the FK/GK Series for the following applications: frequency converters, power modules, automatic control power supply, current sensors for power hybrid applications, and high current applications for the automotive market.
TGHD Series Non-Inductive High Power Resistor
Using the SOT-227 package, the TGHD series features flat type, 100W high power resistors that require an air-cooled heatsink or water-cooling to reach peak performance. These resistors are offered either with quick connect tabs or flywire leads. The TGHD Series is a great option for applications such as harmonic filters, surge protection, dummy loads, high-frequency amplifiers, and many more!
