Through hole resistors, also known as through-hole components, use leads that pass through the board before being soldered to the copper pads on the board. The lead lengths vary from a few millimeters to a few millimeters. Through hole resistors are the most commonly used in electronic components, found in almost all electronic devices. The advantages of these resistors include their large operating temperature range, precise resistor ratings, and low cost.

WW10JT3K00 is a type of through-hole resistor that is made from a thermally coupled resistor network, which is designed with a 5 Ohm resistor in the form of a power torque resistor. This type of resistor is designed to provide a reliable, stable, and precise current-limiting solution. The resistors feature a low temperature coefficient and a high reliability temperature range, as well as a low power consumption and excellent thermal resistance. Due to its low mounting profile and high geometrical tolerance, the WW10JT3K00 is suitable for installing in limited spaces.

The typical application of WW10JT3K00 is power limiting. It is used in current limiters to prevent output circuits from exceeding the DC current that they are designed to operate at. This power limit control is important in circuit designs that require rapid current surges, such as those in the automotive industry.

The working principle of the WW10JT3K00 is that a current limiting device is connected in series with the circuit, and consists of a resistor and a thermistor. The thermistor is a temperature-sensitive resistor with a temperature-dependent resistance that can be used to increase the resistance in the circuit. When a current limit is set, the thermistor is switched in and the current is limited accordingly through the thermoristor.

The thermistor is connected to the resistor and the output current is measured with a digital current probe and a control circuit. When the current exceeds the limit, the voltage across the resistor is increased which in turn increases the resistance of the thermistor, thus increasing the current limit. The digital current sensor is used to measure the current through the resistor and the control circuit is used to measure the total current. When the total current exceeds the limit, the thermistor is switched on and the current through the resistor is limited.

In conclusion, the WW10JT3K00 is a through-hole resistor used in current limiting applications. The thermally coupled resistor network is designed with a 5 Ohm resistor in the form of a power torque resistor, and the resistors feature a low temperature coefficient and a high reliability temperature range. The thermistor is connected to the resistor and the output current is measured with a digital current probe and a control circuit. When the current exceeds the limit, the thermistor is switched in and the current is limited accordingly through the thermistor.
