Resistors are two-terminal parts used for limiting current, timing applications, and voltage division. Resistors complement components like microcontrollers or integrated circuits for various operations like filtering and biasing.

components like microcontrollers or integrated circuits for various
operations like filtering and biasing. Variable resistors are used to
change the properties of a circuit. Current sensing resistors are used
to measure the current in a circuit. Ohms is also known as the unit
of resistance. There are types of high precision resistors that differ
from each other in size and performance. So, how do you choose
from these variants? It's simple; you have to see which one has the
most optimum use for your work.
HERE ARE THE DIFFERENT TYPES OF
METAL FILM RESISTORS
This resistor has high precision, but the temperature coefficient and
the distribution parameter index are lower than the others. It is
generally cylindrical and mainly
equipment, electronic medical equipment like in SRT resistors, test
and measuring equipment.
WIRE-WOUND PRECISION RESISTORS
Constantan, manganin, or nichrome alloy wire on a ceramic
skeleton is what high precision resistors are made of. The surface is
often sheathed with protective paint or glass varnish, and there are
mainly two types, fixed and adjustable.
METAL FOIL PRECISION RESISTORS
The ultra-precise photo etching process used for the resistor circuit,
A metal foil with known and controllable characteristics, is laid on
a unique ceramic substrate.
The approach combines the essential elements of low-Temperature
Coefficient of Resistance,
long-term stability, no inductive
reactance(Flow of AC current), no ESD induction(static electricity
or electrostatic induction).
In conclusion, you will notice that precision resistors mainly use
thin film and foil technology. Among them, you will see that the
electrical performance of the foil resistors is superior. It is because
it achieves almos
