Trimmer potentiometers are a key component of many electronic devices and systems, allowing manual adjustment of the impedance in circuits. This article explores the application field and working principle of the 35WR100LFTR trimmer potentiometer.

Trimmer potentiometers are divided into surface-mount designs, where they are soldered flat onto a circuit board, and axial-lead designs, which can incorporate an integral switch, depending on the application. Single-turn, multi-turn, and continuous-turn designs are all available, with the most common being the single-turn trimmer, a variable resistor whose resistance can be set to one of several values. The 35WR100LFTR is a single-turn, surface-mount trimmer that has been developed to provide reliable performance in a variety of commercial and industrial applications.

The 35WR100LFTR trimmer potentiometer offers an adjustable resistance range of 10 ohms to 100 ohms, with a resolution of 0.1 ohms. The device has a rated voltage of 1.8V and a rated current of 10mA, and is available in a standard 6-pin SOT-23 package. The trimmer is also available in an SMD version, designed for pick-and-place automation in the industrial manufacturing process.

The 35WR100LFTR trimmer potentiometer is designed for use in a wide range of applications. In automotive electronics, such as car stereos, it is used to adjust gain and equalization. In medical equipment, it can be used to adjust precision control settings, while in consumer electronics, such as radios and amplifiers, it is used to regulate audio volume. It is also used in HVAC systems to adjust the set temperature and in security systems for regulating alarm thresholds.

The 35WR100LFTR trimmer potentiometer works by using a small wiper that slides along a resistive element, allowing the resistance to be adjusted over its rated range. The presetting of the resistance is adjustable by a screwdriver or other tools inserted into the wiper, changing the sliding contact on the resistive element and thus adjusting the resistance. As the wiper is moved, a set of contacts on the potentiometer also move, providing a reference signal for monitoring the position of the wiper and any changes in the resistance setting.

In summary, the 35WR100LFTR trimmer potentiometer is a surface-mount, single-turn device designed for use in a variety of commercial and industrial applications, including automotive, medical, consumer, and security electronics. It has an adjustable resistance range of 10 ohms to 100 ohms, and offers a reference signal for monitoring the position of the wiper and any changes in the resistance setting. The device works by using a wiper that slides along a resistive element, allowing the resistance to be adjusted over its rated range.
