Power Through Resistor Suggestions 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 resistor types are available for various applications. Each of them retains the technology and application issues’ understanding.

Manufacturers should completely understand that users avoid compromising and risking the failure of the component or system through stand resistor product usage. These are not obtaining the main specification required. However, they were known to be the closest materials. There are also manufacturers that offer application-specific high voltage resistor products that come in low up to medium volume.

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.


In terms of the lower current applications, the physical length of the device of about five to ten kilovolt. This is arching around the body of the resistor leading to a significant problem. Aside from that, other high voltage resistors have been using the spiral paths of a darker metal oxide which is present in ceramic. Such kind of a high voltage resistor has been referred to as the “tiger stripe resistor”. Peak voltage capability is on body length’s function. Its voltage is about 50 kilovolt. One type of resistor is the non-inductive tubular resistor. This may also be the bulk ceramic resistor. Because of a great resistive volume of the material, such kind of resistors should be capable of handling highly pulsed power than the wire wound or metal film 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. Shunt resistors’ electrical specifications include ohms current rating, and power rating. Other specifications involved are the power coefficient of the resistance, temperature coefficient of the resistance and the resistance tolerance.


Ohms measure the material opposition into an electric flow of circuit while temperature coefficient of resistance (or TCR) refers to the change in resistance along with change in temperature. The power coefficient of resistance or PCR is the temperature that arise because of self-heating. In terms of current-sensing shunts, resistance is usually ranging in between 100 µO and 500 mO. The shunt resistor is being used in the current conversion application and it requires high precision.

Shunt resistors’ physical specifications come in different forms. But these include the lead type as well as the resistor materials. The shunt resistors may be bolted, surface mounted, through-hole mounted, and chassis mounted. THT or the through-hole technology and SMT or the surface mount technology are both other popular and common mounting styles. Other lead types available are axial leads, radial leads, gull-wing leads, screw terminals, J-leads and tab terminals.

The shunt resistors that have no leads have been also available and the choices are thick film, wire wound, thin film, metal alloy, metal film, ceramic, carbon film, and metal oxide. A carbon shunt resistor is comprised of resistive, solid, ceramic, and high temperature materials. These were connected by metal contacts. Metal alloy shunt resistors got more than two metallic elements. On the other hand, a wire wound shunt resistor contains thin wire winding in the ceramic rod.

Every shunt resistor differs when it comes to packing method since other passive electronic components have been packed in a tape reel assembly including the carrier tape that has embossed cavities to store 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.
