Through Hole Resistors are a critical component used in electrical circuits for current regulation, voltage limiting and signal conditioning. The C3AR75JT is a three-terminal through-hole resistor from Ohmite that features a low profile, epoxy-coated construction. This resistor is designed for use in confined spaces like inside wall boxes, in ceiling tile grids, under staircases and in false ceilings. Its low profile, epoxy construction also makes it ideal for use in structures with limited heat dissipation.

The C3AR75JT resistor’s application fields span from general-purpose residential, light-industrial and commercial installations to premium-grade industrial and aerospace applications. It is designed to perform in temperatures from -55°C to +155°C and rated at 75W at an ambient temperature of 85°C. The power rating for this resistor will vary depending on the ambient temperature.

The C3AR75JT resistor is designed with a patented over-mold technology which allows the resistor to be mounted into any desired position. The solid epoxy coating on the resistor ensures that it will be protected from moisture, dust, dirt, acids, and other corrosive substances. Additionally, the resistor has a non-conductive adhesive that is designed to remain flexible for years of reliable service. The internal design of this resistor utilizes a low-profile plastic heat sink which dissipates heat quickly and efficiently. The resistor is designed to operate without the need for an additional heat sink.

The C3AR75JT resistor works by controlling current flow through a resistive element. It has three terminals, where one is connected to the power source, and the other two are connected to either a load or ground. The amount of current that passes through the resistor is determined by the resistance of the element, which is inversely proportional to the applied voltage. If the applied voltage is increased, the resistance will decrease, resulting in more current passing through the resistor.

When the load current exceeds the resistor’s rated watts the resistor will start to heat up, thus dissipating the excess energy as heat. This ensures that the resistor does not get damaged by excessive current and voltage. The resistor is designed to survive multiple overloads without failing, due to its excellent thermal dissipation characteristics.

In summary, the C3AR75JT is a three-terminal through-hole resistor from Ohmite that is designed for use in confined spaces. It is designed to perform in temperatures from -55°C to +155°C and has a power rating of 75W at an ambient temperature of 85°C. This resistor is designed for general-purpose residential, light-industrial and commercial applications and is capable of dissipating heat quickly and efficiently. The resistor works by controlling current flow through a resistive element and is capable of surviving multiple overloads without failing.
