The PSM500JB-220R resistors belong to the family of Through Hole Resistors. This type of resistors offer high overload and pulse capabilities, making them suitable for switch-mode converters, power amplifiers, and automotive applications. The PSM500JB-220Rs offer excellent accuracy and good temperature stability, making them suitable for measurement, control and monitoring applications.

The PSM500JB-220R resistors have a total resistance range of 220 ohms. They are available in two packaging forms; one is a through-hole package, and the other is a axial-lead package. The resistors are composed of an oxide ceramic body with an internal pair of nickel wires, both of which are encased in a UL 94V-0 insulation.

The resistors have an operating temperature range of -55°C to +125°C, and a dielectric strength rating of 1,500Volts. The PSM500JB-220Rs offer excellent reliability, with a maximum power dissipation of 1W. Furthermore, the resistors can withstand up to100mW of overload.

The PSM500JB-220Rs are used in a wide variety of applications. Most notably, these resistors are used in high-power amplifier circuits such as those used in car audio systems. The resistors’ high overload capability allows them to withstand large short-term current surges without failing. Additionally, they are used in switch-mode power converters, motor control circuits, and LED lighting systems.

The PSM500JB-220R’s working principle is based on the resistance property of an electrical circuit. The resistor works by limiting the flow of electric current to the device it is connected to. The more resistance the resistor offers, the less current will be allowed to flow through it. This current limiting property makes the resistor ideal for controlling and regulating the flow of electricity in various circuits.

The resistor’s operation is based on the relationship between the applied voltage and the current that passes through it, which is governed by Ohm’s law. According to Ohm’s law, when a voltage is applied across the resistor, a current proportional to this voltage is allowed to flow. The current is equal to the applied voltage divided by the resistance offered by the resistor.

The PSM500JB-220R resistors are used in many applications thanks to their wide range of resistance values, high reliability, and good temperature stability. The resistors’ ability to withstand large short-term current surges makes them particularly suitable for power amplifier and switch-mode power converter applications. Additionally, the resistors are suitable for measurement, control and monitoring applications due to their excellent accuracy and temperature stability.
