HS10 R39 J

Chassis mount resistors, also known as SMD resistors, are widely used in various applications from electronic products to industrial products. They are usually available in a variety of shapes and sizes, with the most common sizes being HS10, R39, and J.

HS10

HS10 is the most commonly used chassis mount resistor. It has a carbon film construction, making it resistant to wear and tear. It is also resistant to corrosion, making it suitable for outdoor applications. The HS10 is usually good for carrying currents up to 1A safely. It has a power rating of 0.75 watts and an operating temperature range of -55°C to 125°C. HS10 resistors are also available in various values, which can be selected according to the application need.

R39

R39 is a metal-film type resistor. It is very similar to HS10, but is more resistant to mechanical vibrations and temperature changes. The power rating is higher than HS10, at 1.2 watts. Like HS10, it is also suitable for currents of up to 1A. R39 resistors can be used in applications that require tight tolerances, as their tolerance is generally lower than HS10.

J

J resistors are the most versatile of the three, as they are available in a variety of materials and sizes. They have a wide range of possible resistances, and are suitable for currents up to 1A. They also have a high power rating of 2 watts and an operating temperature range of -40°C to 150°C. J resistors have a variety of shapes and sizes, making them suitable for a wide variety of applications.

Application Field and Working Principle

Chassis mount resistors are mainly used in various applications, including audio, power, RF, LED, and automotive applications. They are also used in medical technologies, communications, and computer systems. The typical operating principle of chassis mount resistors is based on the Ohm’s Law, which states that the current is equal to the voltage divided by the resistance. The current is then limited by the resistor’s resistance, which in turn prevents the circuit from experiencing any damage due to a higher current.

Chassis mount resistors are an important component of many electronic and industrial applications, and the different types can be chosen according to the application need. It’s important to ensure the right choice of resistor is made in order to ensure a reliable and safe operation.
