Trimmer Potentiometers

Trimmer potentiometers are a type of electronic device with a rotary shaft and three terminals. Typically, these devices are used to control the voltage or current in an electronic circuit. The 1309W103 is a three-terminal trimmer potentiometer manufactured by AKM Semiconductor Inc. It is designed to provide adjustable resistance in applications such as power suppliers, amplifiers, and audio systems.

Application Fields

The 1309W103 is designed to be used in a wide range of applications. It is a small-sized trimmer potentiometer with an operating temperature range of -30°C to +85°C. The device has excellent insulation resistance and is capable of withstanding up to 500V of AC or DC voltage.

The potentiometer is typically used in domestic and industrial power supplies, frequency response adjustment circuits, and low-voltage audio systems. Its fine adjustment characteristics make it suitable for adjustment circuits in precision devices such as high fidelity sound systems and measuring instruments.

The device is also used in automotive applications such as cruise control systems and fuel injection systems. It can also be used to adjust the position of industrial actuators.

Working Principle

The 1309W103 is a 3-terminal trimmer potentiometer with two end terminals and one central terminal. The two end terminals are the start and end terminals of the device and are used to connect the device to the circuit. The central terminal is connected to the wiper which carries the resistance value through its connection with the three-sided resistor.

The wiper is connected to a central control terminal and is adjustable using a screwdriver. Turning the screwdriver adjusts the resistance of the device by changing the length of the three-sided resistor in contact with the wiper. As the wiper is moved, the resistance value changes, allowing the device to be set at any desired resistance value.

The resistance value of the device can be adjusted by turning the control terminal with a screwdriver, or by hand if the device is designed to have a manual control. The resistance value of the device can be changed by up to 20%, depending on the model.

Conclusion

The 1309W103 is a three-terminal trimmer potentiometer capable of providing adjustable resistance in a wide range of applications. Its fine adjustment characteristics make it suitable for use in precision devices such as high fidelity sound systems and measuring instruments. Its ability to withstand up to 500V of AC or DC voltage makes it suitable for use in automotive applications.

The device is easy to use, as it can be adjusted by turning the control terminal with a screwdriver or by manual adjustment. Its resistance value can be adjusted by up to 20%, making it suitable for a wide range of applications.
