Through Hole Resistors

Through hole resistors are a type of resistor used in various electronic circuits. The most common type of through-hole resistor is a carbon-film resistor, which is a resistor made from a film of carbon that is placed in a ceramic sleeve, which is then inserted into a cylindrical hole in a PCB (Printed Circuit Board). Through hole resistors are available in a wide variety of sizes and shapes, ranging from very small to very large.

HHV2WSJT-73-680K Application Field and Working Principle

The HHV2WSJT-73-680K through-hole resistor is a type of carbon-film resistor with an operating voltage of 680 volts. It is a surface mountable chip designed for use in a variety of applications, including high voltage switching, rectifying, high current drive, and high frequency control circuits. The resistor has a temperature coefficient of 0.05%, meaning that it can be used in applications where the temperature changes rapidly. It also has a high pulse load current of 1.88mA and a short-time overload current of 1.4mA.

The working principle of the HHV2WSJT-73-680K resistor is based on the Ohm\'s Law. This law states that the resistance of a circuit is directly proportional to the voltage, and inversely proportional to the current. Therefore, a higher voltage in a circuit will cause a higher resistance, while a lower voltage will cause a lower resistance. The resistance of this resistor is determined by the size and shape of the carbon film placed inside the ceramic sleeve.

The resistor is made up of two layers of the same carbon film material with a diameter less than 1mm. The two layers are joined by a metal conductor. When an electric current passes through the resistor, the carbon film heats up due to the current passing through it. This causes the resistance of the resistor to increase. The resistor can handle up to 680 volts of electricity and temperatures up to 120°C.

Advantages of the HHV2WSJT-73-680K Through-Hole Resistor

The HHV2WSJT-73-680K through-hole resistor is an excellent choice for a variety of high voltage applications due to its high voltage rating and its high pulse load current. Additionally, the small size of the resistor makes it easy to use in circuits where space is limited, such as in high frequency and high current drive circuits. The resistor also has excellent long-term stability and low temperature coefficient, meaning that its resistance will remain relatively constant over a long period.

The resistor is also designed to handle high levels of vibration and shock, making it well suited for use in motion control systems and other industrial applications. Additionally, the resistor is resistant to temperature changes, which makes it suitable for use in applications where the environment is not always consistent.
