Noninductive 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 fly wire leads. The TGHD Series is a great option for applications such as harmonic filters, surge protection, dummy loads, high-frequency amplifiers, and many more!
Features
- #187 Quick-connect tabs or fly wire leads
- Flat-type, 100W high-power resistor
- Air-cooled heat sink or water cooling required
- Higher density packing, vibration-proof, insulation withstand voltage and perfect heat dissipation possible
- TGHDX with wire leads follows the popular SOT-227 land pattern
Applications
- Harmonic filter
- Snubber resistors
- Surge protection
- Breeder resistor
- Dummy load
- Gate resistor
- Dumping resistor for automotive electronics
- Power supplies

Most standard resistors are commonly produced in an axial lead style. The leads extend out horizontally from the body of the part. These parts are used in thru-hole PCB designs. The leads of this mounting design are bent down for insertion. Since the parts are received from the factory without any bends, it offers the end user the option to bend and mount per their application.

What is a Thick Film Resistor?
Thick film resistors are produced by applying a resistive film or paste, a mixture of glass and conductive materials, to a substrate. Thick film technology allows high resistance values to be printed on a cylindrical or flat substrate either covered entirely or in various patterns. They also can be printed in a serpentine design to eliminate inductance, which is preferred in applications with steady frequencies. Once applied, the resistance is adjusted using a laser or abrasive trimmer.
Thick Film Construction
We offer over 20 different series in Thick Film construction. Thick Film parts can be chosen based on mounting, application, and voltage range. They are easily integrated into a heatsinkable package for high-wattage applications. High values can be obtained and high voltage can be applied to thick film products with little change in resistance value.
