Working Principle of the ML90R9FE-R52

The ML90R9FE-R52 is a through-hole resistor which operates on the principle of ohmic resistance. In an ohmic resistor, the current passing through the resistor is proportional to the applied voltage, according to Ohm’s Law. Ohm’s Law states that the current is directly proportional to the voltage and inversely proportional to the resistance.

The ML90R9FE-R52 is constructed from a resistor film pattern that is etched onto a ceramic substrate. The ceramic substrate has a high dielectric constant and allows for a very high resistance value. The resistor film is then covered with a protective film, such as epoxy, to provide mechanical strength and insulation.

When voltage is applied to the ML90R9FE-R52, the current passing through the resistor is proportional to the applied voltage. This, in turn, produces heat, which is dissipated by the ceramic substrate. As the temperature of the resistor increases, its resistance value decreases, resulting in a decrease in the current flowing through it. This mechanism is commonly known as thermal drift.

In conclusion, the ML90R9FE-R52 is a through-hole resistor used in a variety of applications. It is characterized by its high reliability and long service life. It operates on the principle of ohmic resistance, where the current passing through the resistor is proportional to the applied voltage. The resistor is also capable of dissipating heat, resulting in thermal drift.
