Carbon Film Resistor
Resistors are one of the most crucial parts of any circuit. They vary from micro-ohms to mega-ohms in terms of their value. Also, they come in various forms like embedded as a chip in an IC, can be a bare metal or can be in form of a conductive plastic. This Insight will give a detailed exploration of carbon film resistor which has a ceramic core.
Outer Structure
Resistor looks like a solid capsule with leads at both ends which are used to connect it to the circuit.
On the capsule body, there are colored bands, typically four to six in number which tells the value of the resistance.
The resistance of the given resistor is 1000 ohm +/-5% tolerance.
It is interesting to know that the temperature coefficient is in ppm instead of being in °C . This can be explained using a simple example. Consider a resistor with a rating 30 ppm for its temperature coefficient. This means that for every 1°C rise in temperature, the resistance would not change more than 30/10000000 or 0.000030 ohms.
