3361P-1-100GLF Potentiometers, Variable Resistors

Trimmer potentiometers are variable resistors whose resistance can be adjusted by rotating a knob, making them ideal for applications such as volume control or bias adjustments in radio and television circuits. The 3361P-1-100GLF is a type of trimmer potentiometer manufactured by Bourns, which offers a resistor value of 100ohms and has a slotted shaft for adjustment. It is a carbon film trimmer with three terminals, two of which are connected to the resistive track while one is commonly connected to ground.

The 3361P-1-100GLF is usually used in a wide variety of applications. It can be employed in audio applications such as amplifiers or mixing consoles for controlling gain or providing voltage divider settings. It can also be used in RF circuits for adjusting capacitance ratios, or in oscillators to set up the new frequency range of a device. In power supply systems, these potentiometers can be used to adjust the output voltage and current limiting. Additionally, they can also be used in other medical and industrial devices for adjusting gain, offset, frequency and phase.

The 3361P-1-100GLF is an ohmic device, so its working principle is based on the current-voltage relationship. The adjustment of the knob alters the resistance of the potentiometer’s track, which in turn affects the current and voltage values across the terminals. When the wiper is moved along the resistive track, the resistance changes and the voltage follow suit, which is functional to the application for which the potentiometer is placed.To further explain the inner workings of the 3361P-1-100GLF, consider the following example. Imagine a circuit with the 3361P-1-100GLF connected between the positive and negative power supply rails. When the wiper is turned clockwise, the resistance value gradually decreases, and consequently the current increases. However, when the wiper is moved in an anti-clockwise direction, the resistance increases, and the current decreases.

In conclusion, the 3361P-1-100GLF is a versatile trimmer potentiometer manufactured by Bourns for a wide variety of applications. It has a slotted shaft for easy adjustment, and its ohmic working principle allows for the manipulation of current and voltage values in a circuit. With its resistance value of 100ohms, the 3361P-1-100GLF is a great choice for audio, RF, power supply, medical, and industrial applications.
