Through Hole Resistors are electronic components that are widely used in circuits for voltage and current regulation, signal processing, and more. MRS25000C4023FCT00 is an example of such resistors.

The MRS25000C4023FCT00 is a molded PHIP resistive element in a TO-125 package with the letters and numbers indicating its properties. The “MRS” abbreviation stands for “Molded Resistor Series” which is the family of resistors it belongs to and it is manufactured by Walsin Technology Corporation. The “25000C” indicates that the rated power of this resistor is 25 Watts, that it is a Through Hole mounting type and that the terminal mounting type is the C-Lock. The resistor has a nominal resistance value of 40.2 ohms and a tolerance of ±5%, while the “FCT00” specifies its termination type, which is a Full Crimp Termination.

The MRS25000C4023FCT00 fulfills certain requirements, such as long-term stability, low noise, and high-precision current regulation through its basic characteristics. The ceramic surface provides insulation from ambient temperature and physical shock. The maximum working voltage is 500V, with a pulse voltage of 630V. It also has a temperature coefficient of temperature in the range of ± 100 ppm/°C, which helps to maintain accuracy over temperature changes.

The MRS25000C4023FCT00 is designed for industrial applications, especially in automation and motor control. It is used in circuits demanding precise current regulation and as a high-power resistor. Being a Through Hole Resistor, it has to be soldered and mounted on the circuit board manually.

The working principle of the MRS25000C4023FCT00 is simple. When the current flowing through the resistor increases, heat is generated due to the resistance. The resistor deforms and changes its resistance value, thereby limiting the current flowing through the circuit. The resistor works on the Joule heating effect, where a voltage is applied across a resistor and the current that flows generates heat.

The MRS25000C4023FCT00, as a Through Hole Resistor, is effective in industrial applications where current regulation and power handling is necessary. Furthermore, its high-power ratings, stability at operating temperatures, and insulation from ambient temperatures make it suitable for even the harshest industrial environments. Its ability to function both in AC and DC applications makes it a versatile solution for a variety of different uses.
