Moreover, this through hole resistor can be used to construct various types of protective circuits or DC and AC control circuits.

Working Principle

To understand the working principle of the ALSR103K300FE12, one must first understand how a resistor works. In general, a resistor is an electronic component that reduces the amount of current that passes through a circuit. Its work is based on Ohm\'s law which states that the current flowing through a resistor is proportional to the voltage across it. A resistor also dissipates energy in the form of heat.

The ALSR103K300FE12 is a resistor with a temperature coefficient of 100ppm/°C, meaning it can maintain a consistent resistance over a wide temperature range. Its resistance is determined by the amount of resistive material used in its construction and it can reach values up to 300K Ohm. The temperature coefficient of the ALSR103K300FE12 helps protect electronic devices from temperature-related changes in resistance.

When the ALSR103K300FE12 is used as a fuse, it operates in a manner similar to a thermistor. In this case, an increased current causes the resistor to heat up, which can eventually cause it to open. The ALSR103K300FE12 can also be used as a voltage regulator. In this case, the resistor is connected to a voltage source and its resistance is adjusted to limit the voltage applied to the load.

In summary, the ALSR103K300FE12 can be found in a variety of automotive and electrical applications. It is also used as a fuse, circuit breaker or voltage regulator. Its resistance is determined by the amount of resistive material used in its construction and it is temperature-stable.
