The H4698KBCA is ideal for applications where space is limited and where a high degree of reliability is required. Its power rating and operating voltage make it suitable for power supplies, power amplifiers, motor control systems, and other power-intensive applications.

The H4698KBCA can also be used in distributed networks, computer systems, and other IT-related devices to protect against over-current and short circuits.

Working Principle

The H4698KBCA Through Hole Resistor operates on a negative temperature coefficient (NTC) resistance element. This means when the temperature of the resistor element increases, its resistance decreases. Because current is inversely proportional to resistance, the resistor operates on the principle that when a current passes through it, it will cause the temperature of the resistor element to increase, which then causes the resistance to decrease and restricts the current.

This can be applied to either a voltage control circuit or a current control circuit. In a voltage control circuit, the resistor will limit the voltage by increasing its resistance to the current when the voltage rises past a certain level. In a current control circuit, the resistance will limit the current by increasing its resistance to the current when the voltage rises past a certain level.

The resistor also includes a mylar insulator, which prevents the current from flowing from the resistor element to any other part of the system. This ensures that the current is limited to the predetermined level set by the resistor.

Conclusion

The H4698KBCA Through Hole Resistor is an ideal component for a variety of applications, including power supplies, power amplifiers, motor control systems, distributed networks, and computer systems. Its operating principle, based on an NTC resistance element, allows it to provide control of both voltage and current. It also includes a mylar insulator, which provides effective protection against over-current and short circuits.
