Through Hole Resistors

The 40J25R is an example of a through hole resistor from the electronic component family. Through hole resistors are discrete components that are inserted or ‘through’ a hole in a circuit board. They are the traditional resistors used in electronics and are often used in DC circuits. They are very accurate, reliable, and have a high power handling capability.

Application Field and Working Principle

Through hole resistors are mainly used in power applications such as power supplies, lighting, motors and high voltage DC circuits. Some examples are motor speed control or ballasts in fluorescent light fixtures. They are also used in high power audio and RF amplifiers, switchmode power supplies and voltage regulator circuits. Other applications include heating elements, resistors in actuator circuits, over-current protection and edge trimming.

The 40J25R is encased in an insulating material and its resistance is determined by the shape, size, and material of the resistor. The electrical resistance of the resistor is affected by temperature so a compensating element is included in the design. The resistance is also determined by the resistance wire material and its length, and the cross sectional area of the resistor body.

A resistor is a passive two-terminal electrical component that implements electrical resistance as a circuit element. When a voltage is applied to the resistor, a current is proportional to the applied voltage. The basic working principle of a resistor is based on Ohm’s law. This states that the current passing through the resistor is proportional to the voltage across it, provided the temperature remains constant. By changing the resistive value of the resistor different voltage and current values can be achieved.

The 40J25R is designed for use in applications with high voltage and power requirements. It also features excellent humidity and temperature stability. It has low inductance, low thermal resistance and has a wide operating temperature range from -55 to +125 degrees Celsius. The 40J25R has a wide resistance tolerance from 2-10% depending on the type of resistor. It also has a power rating of 25 Watts and a breakdown voltage of 5KV.

The 40J25R is suitable for various applications such as inverters, ballasts, and hybrid circuits. It is also used in motor drive circuits, home appliances, and real-time monitoring devices. It’s also suitable for heavy-duty commercial and industrial circuits.

Through hole resistors are reliable, reliable, accurate, and can handle high power loads. The 40J25R in particular is designed to take on high voltage and power requirements while offering excellent humidity and temperature stability. It can be used in a variety of applications from simple DC circuits to high power and high voltage circuits. Its wide operating temperature range and low thermal resistance make it an ideal choice for many design requirements.
