Through Hole Resistors play an important role in many different electronic systems and there are several different types of resistors available. Of these, the OY150KE is a type of through-hole resistor that is used for a variety of electrical and computational applications. This article will explore the application field and working principle of the OY150KE.

The OY150KE through-hole resistor is a five watt, axial lead metal alloy resistor featuring a tolerance of 5%, a max. working voltage of 500V and an operating temperature of up to 85°C. This type of resistor is best suited for use in low frequency circuits and is also a common choice for power supply filters. It is a more cost-effective alternative to the costly high-power through-hole resistors and has a relatively small size, making it a great choice for applications where space is at a premium.

The OY150KE is primarily used in applications such as power amplifiers, high-power dc-ac converters, low-voltage and high-current motor control circuits, fluorescent light dimmers, voltage regulators and switching power supplies. It is also used in applications requiring a reliable, high-power safety resistor, such as in motor protection systems or other high-voltage/high-current circuit control systems.

The OY150KE has a number of unique design features that make it suitable for a range of application fields. It is constructed using a single thick film layer applied to a nickel-iron substrate. This construction gives it excellent stability and good heat dissipation, making it ideal for high-temperature applications. The resistor is then coated with a special film to protect it from corrosion and static electricity.

The OY150KE is designed to be compatible with both AC and DC circuits and can handle currents up to 2 Amps. It also features a non-linear heat coefficient and has a low self-inductance, enabling it to be used in high-frequency circuit applications. The resistor also features a high temperature coefficient of resistance that helps to protect it against sudden changes in load or voltage.

The working principle of the OY150KE is fairly simple. When current passes through the metal-alloy resistor, it creates a voltage drop over the resistor that is proportional to the amount of current flowing through it. This voltage drop results in a resistance, which determines the amount of electrical resistance and power dissipation that the OY150KE can handle.

In summary, the OY150KE is a popular type of through-hole resistor that is used for a variety of applications. Its unique design features and low cost make it a great choice for applications that require a reliable resistor with a high power rating and a relatively small size. The OY150KE is also relatively simple to use, as its working principle is based on a voltage drop caused by current passing through the resistor.
