Through Hole Resistors are one of the most widely used components in the entire world. The H4280RBYA is a through hole resistor specifically designed for applications where high overload currents are present. It is made up of three components: a metalized polycarbonate film, a ceramic core and a two-layer copper plated aluminum tube. This combination creates a strong and reliable solution for high current applications.

The metalized polycarbonate film is embedded in the ceramic core and serves to maintain the resistor\'s performance over life. This material has a high thermal resistance, high pollution resistance and a wide temperature range, allowing it to withstand up to 700 degrees Celsius without damage. It also has very low leakage current so as to not affect the overall performance of the resistor.

The ceramic core of the resistor works in conjunction with the metalized polycarbonate film to provide an increased degree of insulation and provide increased mechanical strength. It also serves to protect the two-layer copper plated aluminium tube from corrosion due to high temperatures and humidity.

The copper plated aluminium tube is designed to minimise losses due to skin effect. This ensures the maximum performance from the resistor despite the high current operating within it. It is also highly resistant to thermal shock and other forms of mechanical damage and is designed to last a long time with minimal maintenance.

The working principle of the H4280RBYA is quite simple. The metalized film acts as a resistor when electric current passes through it. The ceramic core and the two-layer copper plated aluminum tube provide additional insulation and mechanical strength to the resistor. The resistor absorbs the energy from the current, resulting in a steady voltage drop across the resistor. This voltage drop is what provides the power to the appliance or device connected to the resistor.

The H4280RBYA is designed to handle currents of up to 5.5 A and has a maximum operating temperature of 150 ̊C. Due to its high overload current capacity and the strong insulation provided by its components, the H4280RBYA is one of the most popular resistors used today.

In conclusion, the H4280RBYA is a through hole resistor specifically designed for applications where high currents and high temperatures are present. It is made up of a metalized polycarbonate film, a ceramic core and a two-layer copper plated aluminum tube. The metalized film acts as a resistor, while the ceramic core and aluminum tube provide additional insulation and mechanical strength. The resistor is able to withstand currents up to 5.5 A and temperatures up to 150 ̊C, making it an excellent choice for applications where high current and/or high temperature is a concern.
