Chassis Mount Resistors, such as the UAL25-12RF8, are designed to absorb energy losses that can result from shunting current to ground. This type of resistor offers superior performance over traditional resistors due to their increased power rating, wide range of operating temperature, shock resistance and corrosion protection. A UAL25-12RF8 is a variable wirewound resistor that offers superior performance and efficiency in a range of applications. It has a resistance value range of 0.15Ω-3.6kΩ and it can handle a maximum rated current of 5A.

The UAL25-12RF8 is used mainly in high-frequency, high-power applications, such as high voltage switching equipment, DC power supplies, high-speed audio amplifiers, and industrial process control. The device has a high frequency response and quick transient response, which makes it ideal for applications requiring a fast response time. It also offers excellent frequency band width and power capability, making it suitable for a wide range of equipment.

The UAL25-12RF8 is equipped with several features that make it ideal for high power applications. These features include:

• High power capability: Its maximum rating of 5A at 100 W is ideal for equipment such as DC power supplies, high-speed audio amplifiers, and industrial process control.
• High frequency response: With a high frequency response, the device responds quickly to voltage changes. This ensures better control and improved safety.
• Shock resistance: Its shock resistance helps to protect it from impact damage, ensuring greater durability.
• Corrosion protection: Its corrosion protection prevents rust and oxidation, increasing its overall lifespan.
• Wide operating temperature range: The UAL25-12RF8 has an operating temperature range of -20°C to +105°C, which makes it suitable for a wide range of environments.

The UAL25-12RF8 is constructed from high-temperature wire and encapsulated in a ceramic body. The device\'s high power rating is made possible by its high thermal conductivity and low thermal mass. This allows it to dissipate heat quickly and efficiently, increasing its overall performance. The device is also designed to be vibration and shock resistant, making it ideal for use in industrial and marine environments.

The working principle behind the UAL25-12RF8 is based on the Ohm\'s law, which states that the current passing through a resistor is directly proportional to the voltage applied. When the voltage is applied, the resistor creates a small voltage drop, which is proportional to the resistance value. This voltage drop is used to dissipate the energy losses resulting from shunting current to ground.

The UAL25-12RF8 is designed and tested to meet industry safety standards, such as UL, CE, CSA, and RoHS, ensuring maximum product reliability and durability. As such, the device is suitable for a wide range of commercial and industrial applications.
