Resistor Professionals The high voltage resistors can be found in various designs. Each of these resistors is used for different purposes and applications. Most manufacturers are focused on delivering designs of application and customer specific resistors. They usually come in low and medium volume. These resistor types are available for various applications. Each of them retains the technology and application issues’ understanding.

These manufacturers know that users are trying to prevent risking and compromising the component and system failure. They do this through using standard products of resistors. They do not achieve the accurate specification needed; however, these have been the closest available materials. There have been manufacturers that are offering products for high voltage resistor that are application-specific and are available in low to medium volumes.

The major application of a high voltage resistor has been the circuit protection sensitive elements in power suppliers, but other applications include motor control, anti static system, medical device, divider circuit, military system, balancing and emitter resistor. The capability to manufacturer depends on some elements. These involve the TCR or temperature coefficient of resistor, wattage ranges, ohmic ranges, and voltage.

High voltage resistors have special requirements. These requirements are asked in the aspect of high voltage applications. The typical carbon film resistors’ ¼ watt are available in various electronics ranges from 250 volts to 500 volts which has been under the kilovolt level required. The limitation of the voltage has been set through issues on power dissipation such as the 10k resistor having 1 kV across this dissipates 100W which is excessive to the common ¼ watt.


Even in terms of a low current application, physical length of a device of about one centimeter indicating about 5 to 10 kV which arch around a resistor body is a big problem. Aside from that, other high voltage resistors have been using the spiral paths of a darker metal oxide which is present in ceramic. This is another type of high voltage resistor. This is known as tiger stripe resistor. Its capability of peak voltage is usually the body length function and they come in voltage that is ranging about 50 kiloVolt. One type of resistor is the non-inductive tubular resistor. This may also be the bulk ceramic resistor. Due to large resistive material volume, these types of resistors must have the ability to handle highly pulsed power compared to the metal film or wirewound counterparts. It has been done for ensuring that they will be suitable for rapid energy dumping as well as higher energy pulse works.

Shunt resistors have been integrated in the parallel form with the component or instrument in order to divert the electrical current. These have been providing the alternative paths for current just in case there is failure and may be utilized to complete the reduction in the sensitivity of input from an input line going to the ground.

A current shunt resistor is a low resistance and passive electronic device that is used to measure AC (alternative current) and DC 9direct current). This is directly proceeding to the voltage drop in which currents created all throughout the resistnace. The electrical specifications of the shunt resistors involve resistance tolerance, power rating, resistance power coefficient, resistance temperature coefficient, ohms, and current rating.


Ohm is used to measure the material’s opposition into the flow of electricity circuit. On the other hand, the temperature coefficient of resistance (TCR) is the resistance change with change in temperature. PCR or the power coefficient of resistance is referring to a temperature. This temperature rises because of self-heating. For the current-sensing shunts, the resistance usually ranges from 100 µO up to 500 mO. A shunt resistor can be applied in current conversion. This is the aspect in which high precision has been required.

The physical specifications for the shunt resistors involve resistor materials and lead type. The shunt resistors may be bolted, surface mounted, through-hole mounted, and chassis mounted. Through-hole technology (THT) and surface mount technology (SMT) have been the other typical and well-known mounting styles. Some of the types of lead include J-leads, screw terminals, tab terminals, gull-wing leads, axial leads, and radial leads.

There is also a shunt resistor that has no leads. These are the wire wound, thick film, metal alloy, thin film, ceramic, metal film, metal oxide and carbon film. A carbon shunt resistor is comprised of resistive, solid, ceramic, and high temperature materials. These were connected by metal contacts. The metal alloy shunt resistor contains more than 2 metallic elements and the wire wound shunt resistor has been composed of thin wire winding into the ceramic rod.

Shunt resistors differ in terms of packing methods because some passive electronic elements are packed in the reel tape assemblies along with a carrier tape which embossed cavities for storing individual component. Others have been packed in trays (or trails) and they had been made up of carbon-power and fiber materials as they molded in rectangular outlines containing uniformly spaced matrices of pockets. Some of them have been packed in a tray (trail) and were comprised of both fiber and carbon-power materials. At the same time, these are molded in a rectangular form that has numerous pockets which were uniformly spaced.
