Through Hole Resistors are one of the most widely used components in electric circuits. They are used to control current and voltage in a circuit, and are invaluable for protecting other components from overload or excessive stress. The H8127RBZA is a through hole resistor made by the company Rohm, designed for use in automotive and industrial applications. Below we will explore its application fields and working principles in greater detail.

The H8127RBZA is a robust and reliable through hole resistor, designed to be used in applications where heat tolerance is an important factor. It has a maximum operating temperature of +125C, and a peak pulse power dissipation of 1500W, which makes it a great choice for power control applications. It also has a surge voltage capability of 600V, and a response time of 0.8µs, making it suitable for use in applications involving high-speed switching and control.

In terms of its application fields, the H8127RBZA is suitable for use in various automotive and industrial applications. It can be used to control and regulate power in electric vehicles, solar power systems, and charging stations. It is also useful for motor control, current sensing, inverter control, power factor correction, and harmonic suppression applications. This makes the H8127RBZA a versatile and reliable through hole resistor.

The working principle of the H8127RBZA is fairly simple. It utilizes a PTC element, which is a thermistor material that changes its electrical resistance in response to changes in temperature. This PTC element is connected in series with an electro-thermal ceramic element, which is used to provide the necessary heat dissipation and temperature control. When the current through the resistor exceeds the surge voltage, the PTC element generates heat and the temperature of the ceramic element rises. This in turn reduces the current through the resistor and thus limits the maximum power dissipation.

The H8127RBZA is an excellent choice for applications where high temperature tolerance and fast response times are important considerations. It has a wide range of applications in automotive and industrial settings, and its robust construction and reliable performance make it a great choice for applications which require reliable power control. Its simple working principle makes the H8127RBZA a great choice for those looking to quickly and easily find and install a reliable through hole resistor.
