Wirewound Resistor Strategies These high voltage resistors are available in various designs and they are used for more specific purposes. Most manufacturers are focused on delivering designs of application and customer specific resistors. They usually come in low and medium volume. These types of resistors can be used in numerous applications and they are retaining the complete understanding of resistors’ application and technology issues.

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. These do not get the exact specification being asked but they are actually the closes materials available. There have been manufacturers that are offering products for high voltage resistor that are application-specific and are available in low to medium volumes.

A high voltage resistor major application is circuit protection sensitive elements present in a power supply. Other applications include motor control, medical devices, anti static systems, balancing and emitter resistors, military systems (RADAR, SONAR) and divider circuits. 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 got special requirements in terms of applications on high voltage. 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 voltage limitation is set through the power dissipation issues like a 10k resistor with one kilovolt across it dissipating 100 watts.


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. Apart from it, some high voltage resistors were using spiral path of the dark ceramic metal oxide. This high voltage resistor is called 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 essential kind of this resistor has been the non-inductive bulk ceramic or tubular 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 is accomplished to obtain rapid energy counterparts. At the same time, this will also suit rapid energy dumping works.

The shunt resistors were associated in a parallel form along with an instrument or the component for diverting electrical current. Such kinds of resistors are designed to give alternative path for current in case there is a failure. They can be used to reduce input sensitivity coming from the input lines proceeding directly to the ground.

Current shunt resistors were generally low in resistance and passive electronic devices used to measure AC (alternating current) and DC (direct current) going through the voltage drop in which currents created throughout resistance. Shunt resistor electrical specifications include power rating, temperature coefficient of the resistance, resistance tolerance, current rating, ohms, and power 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. The shunt resistor is being used in the current conversion application and it requires high precision.
Resistor Shunt

Shunt resistors’ physical specifications come in different forms. But these include the lead type as well as the resistor materials. A shunt resistor can be surface mounted, chassis mounted, through-hole mounted, and bolted. Surface mount technology (or SMT) and through-hole technology (or THT) were both common styles of mounting. The other kinds of lead are screw terminals, J-leads, and tab terminals. There are also gull-wing leads, radial leads, and axial leads available.

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.
