3386P-1-253T

Trimmer potentiometers are an invaluable tool in calibrating circuitry with precision voltage settings, sensing electric current and affording protection to parts of a circuit from becoming overloaded. They are most often used in industrial, consumer and aerospace electronics applications.

3386P-1-253T is designed to enable adjustment with a minimum of tools in a variety of electronic devices. The 3386P-1-253T is a single-turn/multi-turn trimmer potentiometer which can typically be found in power supply circuit boards, LCD brightness adjustment, automobile nav systems, laser printers, computer peripherals and other portable electronic devices.

The 3386P-1-253T is a potentiometer with a resistor element that is adjustable to varying resistance values by turning the adjustment knob. The resistor element can also have a switch incorporated into it which is standard with the 3386P-1-253T. There are three pins, one end pin connected to the adjustable wiper arm, one center pin connected to one side of the resistive element and one opposite pin connected to the other side of the resistive element.

The 3386P-1-253T has a resistive power rating of 1W and a dielectric withstanding voltage of 500V AC. It also have a linearity tolerance of 5%. The resistance range for the 3386P-1-253T is 10K, 20K, 50K, 100K, 200K, 250K, 500K, 1M and 2M ohms. The adjustment torque is defined as 1.0Ncm nominally and with an operating temperature range of -40°C to +65°C.

The 3386P-1-253T provides good quality performance in a variety of operation environments. Its robust construction ensures the unit will stand up to vibration and shock in applications such as motors and automotive systems. Its resistance stability ensures the desired adjustment setting will remain intact despite temperature fluctuations.

The working principle of 3386P-1-253T is a simple one. A knob rotates the resistor element on the three contact pins, and the electrical resistance between two of the pins will change. This resistance change is then monitored by different circuit components. In a typical application, the variable resistance is used to change the output voltage of a regulated power supply, or to adjust the brightness of an LCD display.

The 3386P-1-253T trimmer potentiometer offers an excellent cost-to-performance ratio, and can be found in various industrial, consumer and aerospace electronics applications. It offers reliable and precise adjustment with a minimum of tools, and works in vibration and shock prone environments. It is the perfect choice for applications requiring a precise and durable adjustment of configurations.
