CARBON FILM FIXED RESISTORS
Carbon film resistors are the earliest and a still popular type of resistor and
carbon film resistors are made by breaking down hydrocarbon gases at high
temperature in a vacuum to form a carbon deposit on the surface of a
cylindrical substrate. Trimming to value is accomplished by the cutting of
spiral grooves. An alternative method of producing carbon film is to
mechanically apply carbon “dust” dispersed in a curable polymeric binder.
The material is painted on the substrate in a spiral pattern and cured at a
moderately elevated temperature. Resistor types include general purpose.
Through hole (dip type) and surface mount devices. Also included are specialty types, such as high power, high
voltage and fusible resistors. Carbon film resistors also come in nonflammable coating that can withstand high
temperature. Token carbon film resistors come with competitive prices and widely used in the electronics, and
d
consumer electrical industries.

METAL FILM RESISTORS
Metal film resistors use nickel-chromium or a similar alloy deposited on a
ceramic rod by a vacuum process of evaporation or sputtering. The final
resistance value is (most commonly) defined by cutting an insulating path
through the film along the length of the rod while keeping it in rotation. This
electrically lengthens the resistor by producing a helix current path around
the rod from end-to –end. The technology is capable of supporting precision
characteristics over a broad resistance range. Resistor types include axial
Through Hole through-hole and metal film fusible resistor on special
purpose.
