Trimmer Potentiometers are mainly used to adjust circuits when excellent accuracy and stability are required. The 3009Y-1-501 is a trimmer potentiometer that is widely used for commercial, industrial, and military applications. It is a dual-gang potentiometer with a single-turn mica wafer below the actuator. This trimmer has a 9 mm threaded bushing with an outside diameter of 20 mm and a length of 7.9 mm.

The 3009Y-1-501 is a mechanically rugged trimmer with a long electrical life. This minimizes leakage and allows the device to withstand temperatures up to 300°C, so it is suitable for use in a wide variety of applications requiring long-term reliability and performance. It is available with a variety of resistance values ranging from 250 ohms to 10 kohm, a normal power rating of 2 watts, and an operating temperature range of -55°C to 300°C.

The major application fields of the 3009Y-1-501 include automatic gain control in radio receivers, volume control, fine circuit adjustment in TV, RF amplifiers, and calibration of mixing modules. In addition, this trimmer potentiometer can be used for fine-tuning of output voltages, establishing gain of audio amplifiers, and offsets in high-performance amplifiers. It can also be used to adjust the gain of converters, oscillators, and amplifiers.

The working principle of the 3009Y-1-501 lies in its ability to be mechanically adjusted, allowing electrical properties such as resistance, power, inductance, and capacitance to be changed from its original values. When the mica wafer is moved, the mechanical movement of the wafer is translated into electrical impulses which can be regulated according to the requirement. This is accomplished by encapsulating the wafer and bushings in a rigid, epoxy-filled housing. The electrical output is steady and linear, and the device is very reliable over its long life.

The 3009Y-1-501 is an economical and reliable trimmer potentiometer that can be used in a variety of applications that require high accuracy and long-term reliability. The device offers the advantages of excellent repeatability and adjustment accuracy, and is suitable for both high-precision and low-cost applications. Its rugged construction and long life make it a valuable and cost-effective choice for a wide range of applications.
