Through Hole Resistors are one of the most common types of electronics components used in a wide array of electrical and electronic systems. The HVW1/21M000JLB is a through hole resistor that is widely used in a variety of applications. In this article, we will explore the application field and working principle of the HVW1/21M000JLB resistor.

Application Field of HVW1/21M000JLB

The HVW1/21M000JLB is a high-voltage resistor with a rated voltage rating of 21000 V. It is used for surge protection and circuit protection, particularly in applications such as high-voltage power supplies, telecom systems, grounding systems, and safety-critical systems such as medical equipment or auto-piloting systems. Moreover, due to its high-voltage rating, it is also suitable for insulating voltage transformer circuits, high-voltage switchgears, and electronic and industrial equipment.

Working Principle of HVW1/21M000JLB

The HVW1/21M000JLB resistor works through a process called ‘current sensing’. In this process, a small voltage drop is created across the resistor which is proportional to the current flowing through the circuit. This voltage is then used to measure the current in the circuit, allowing for circuit protection and surge protection. The resistor is also capable of providing protection against transient over-voltages due to its high-voltage rating.

In addition to current sensing, the HVW1/21M000JLB resistor also works as a temperature-dependent resistor. This means that the resistance of the resistor decreases with increasing temperature, allowing for improved over-current protection in high-temperature environments. Furthermore, the resistor is also able to maintain a low heat buildup even at high power ratings, meaning that it does not need to be replaced frequently.

Conclusion

The through-hole resistor HVW1/21M000JLB is a high-voltage resistor with a rated voltage rating of 21000 V which is used for surge protection and circuit protection. It also works through a process of \'current sensing\' and is temperature-dependent, meaning that the resistance of the resistor decreases with increasing temperature. This provides improved over-current protection in high-temperature environments, and allows for a lower heat buildup at high power ratings.
