Through Hole Resistors are one of the most common electrical components used in electronics circuits. They are designed to provide a resistive path between two points of the device, allowing different electrical currents to flow through them. One specific type of through hole resistor is the CW0103K800KEE733, which is ideal for use in high voltage and high current applications. This article will explain the application fields and working principles of this particular type of resistor.

The CW0103K800KE733 is a three-terminal through hole ceramic resistor with a maximum working voltage of 800 volts and a typical resistance value of 5,000 ohms. It is designed for use in power applications that require higher voltage and current capabilities than surface mount resistors offer. This type of resistor has excellent temperature and stability characteristics, as well as a long-term reliability rating. In addition, the resistor features a high ESL (Equivalent Series Inductance) and low ESR (Equivalent Series Resistance), which makes it suitable for use in applications that require high radiation or high sensitivity.

One of the most common applications of the CW0103K800KE733 is in DC/DC converters. This type of device is used to step up or step down the voltage of an input source so that it is compatible with the voltage requirements of the target device. The resistor is used to regulate the current or voltage output of the converter in order to protect the sensitive components in the device from being damaged by excessive current or voltage. It also helps prevent the converter from unintentionally resetting due to excessive over-voltage.

The CW0103K800KE733 can also be used in switching power supplies. This type of power supply is used to convert the voltage output of an AC source into a DC voltage. It is composed of a transformer, rectifier, filter capacitor and a switching device. The resistor is used to help regulate the voltage output of the power supply by controlling the amount of current that is supplied to the rectifier. This prevents the switching device from turning on and off excessively, which can cause excessive heat buildup and reduce the reliability of the power supply.

The working principle of the CW0103K800KE733 is quite simple. The resistor acts as a kind of voltage drop on the supply line, which reduces the amount of current that is supplied to the device. This is because the resistor restricts the flow of current, allowing only a certain amount to flow through the device. The voltage drop on the supply line is directly proportional to the resistance of the resistor, so increasing the resistance of the resistor will result in a greater voltage drop on the supply line. As the voltage drops, the current that is supplied to the device is limited, thereby protecting the sensitive components from being damaged by excessive current.

In summary, the CW0103K800KE733 is a highly reliable and efficient three-terminal ceramic through hole resistor that is ideal for use in high voltage and high current applications. Its high ESL (Equivalent Series Inductance) and low ESR (Equivalent Series Resistance) characteristics make it ideal for use in applications that require high radiation or high sensitivity. It is commonly used in DC/DC converters and switching power supplies, where it is used to regulate the voltage or current output of the device in order to protect sensitive components. The working principle of the resistor is quite simple, as it acts as a kind of voltage drop on the supply line, which reduces the amount of current supplied to the device.
