The 7284R1KL.25 is a product from Bourns that belongs to both the rotary potentiometers and rheostats families. The 7284R1KL.25 offers a wide range of features from a very small footprint and it is designed to provide cost-effective functionality. It is used in a variety of applications, including audio, communications, automotives, instrumentation, and industrial electronics.

A rotary potentiometer is essentially an adjustable resistor with three terminals. It is a variable resistor that is used to adjust the gain or output of a circuit. In a rotary potentiometer, the value of resistance is proportional to the physical rotation of the wiper contact on the resistive element. The 7284R1KL.25 is a single-turn trim potentiometer, offering linear resistance values from 0 to 5kΩ with a rocker switch, as well as switchable current levels from 2uA to 39mA with a switchable break before make switch.

A rheostat is a two-terminal variable resistor. It is an adjustable resistor used to control current through a circuit, rather than voltage as with a potentiometer. It is sometimes referred to as a variable resistor because the resistance value can be adjusted. The 7284R1KL.25 is specifically designed as a power rheostat, for use in applications that require a load of up to 2.5A and 0 to 7.5V. It features on-board current limit protection, and it can be operated as a linear variable resistor or a power rheostat, depending on application requirements.

In addition, the 7284R1KL.25 features a wide range of features, including a built-in over-temperature protection, a built-inreverse-polarity protection, and mountable screw terminals for easy connection to external circuits. It also features a high-temperature range of -40 to +85°C, and is available in 6#22 AWG wire. The product is tested to UL, CSA, VDE, CQC, and CE standards, making it suitable for use in a variety of harsh environments.

The 7284R1KL.25 is designed for use in a range of different applications, including automotive, industrial, consumer, and medical electronics. It can be used as a linear variable resistor in applications such as volume control, gain control, fan control, and lighting control, or as a power rheostat in applications such as motor control, variable speed control, and regulator control. It can also be used to regulate current in applications such as power supplies, battery chargers, LED lighting, and motorcontrols.

The working principle of the 7284R1KL.25 is simple. The device is a three-terminal rotary potentiometer or a two-terminal power rheostat. By rotating the knob of the device, the user adjusts the resistance value, making it either higher or lower. The device also features a built-in over-temperature protection and reverse-polarity control, so that it will not get damaged in the event of an unexpected power overload. The 7284R1KL.25 can be used in a wide range of applications, making it an extremely versatile and cost-effective device.
