✔ Carbon Film Resistor Tcr

It has 200 to 600 volts maximum working voltage range. The temperature coefficient of resistance or tcr is one of the main used parameters to characterize a resistor.

Mouser offers inventory pricing datasheets for carbon film resistors through hole.

Carbon film resistor tcr. Carbon film resistors are a form of resistors that use a thin carbon film to limit the electric current flow. See datasheet resistance range. In the past the bulk of the resistor market went to carbon composition products.

Carbon film resistors through hole are available at mouser electronics. The carbon film acts as the resistive material to the electric current. Carbon film resistor construction.

Tcr temperature coefficient of resistance is low 10ppm0c and can be controlled by selecting special wire alloys. However when compared with other forms of thin film resistors carbon film resistors are expensive to produce. Special carbon film resistors are used in applications requiring high pulse stability.

Featuring temperature ranges of 550c 1550c and tolerances of 5 these through hole mounting resistors provide remarkable performance without breaking the bank. 22 w to 15 mw power rating. Carbon film melf resistors series description features brand cma 0204 cmb 0207 high pulse load melf resistors size.

Carbon film resistors circuit specialists carries affordable 18 14 12 and 1 watt rohs compliant carbon film resistors made with tin coated annealed copper wire. It has 200 to 600 volts maximum working voltage range. The carbon film resistor has an operating temperature range of 55 0c to 155 0c.

The resistor consists of a thin carbon layer on a pure ceramic material. 1 to 5 tcr. 04 w to 1 w up to 3 kw single pulse capability special carbon film technology.

0204 and 0207 tolerance. The tcr defines the change in resistance as a function of the ambient temperature. The common way to express the tcr is in ppm0c which stands for parts per million per centigrade degree.

Usually you need the lowest tcr but a higher tcr has special interest in some applications carbon composition resistors. The tcr defines the change in resistance as a function of the ambient temperature. The carbon film resistor is made by placing the carbon film or carbon layer on a ceramic substrate.

The common way to express the tcr is in ppm0c which stands for parts per million per centigrade degree. The generic term film resistor consist of metal film carbon film and metal oxide film resistor types which are generally made by depositing pure metals such as nickel or an oxide film such as tin oxide onto an insulating ceramic rod or substrate. Resistance changes with temperature the temperature coefficient of resistance or tcr is one of the main used parameters to characterize a resistor.

Hence the carbon film blocks some amount of electric current.
