What is the rotary potentiometer used for?
1. Used as a voltage divider: the rotary potentiometer is a continuously adjustable resistor.
2. Used as a varistor: When the potentiometer is used as a varistor, a smooth and continuously changing resistance value can be obtained.
3. Used as a current controller: When the potentiometer is used as a current controller, one of the selected current output terminals must be a sliding contact terminal.
What are the precautions for the use of rotary potentiometer？
The resistor body of the rotary potentiometer is mostly made of polycarbonate synthetic resin, and contact with corrosive objects should be avoided. The terminals of the rotary potentiometer should avoid using water-based flux when soldering, otherwise it will promote metal oxidation and moldy materials; avoid using inferior flux, poor soldering may cause difficulty in tinning, resulting in poor contact or open circuit.
What are the different classifications of rotary potentiometers?
Rotary potentiometer can be divided into two categories: wire wound potentiometer and non-wire wound potentiometer according to the material of the resistor body. Wire-wound potentiometers can be divided into general-purpose wire-wound potentiometers, precision wire-wound potentiometers, high-power wire-wound potentiometers, and pre-adjusted wire-wound potentiometers. Non-wire wound potentiometers can be divided into two types: solid potentiometers and membrane potentiometers, and so on.
User Reviews
What users say about FEETECH
Procured from the company for more than 5 years, from the initial one or two products to the current BOM procurement, the product quality is stable, the delivery is timely, especially the after-sales service is very professional, I hope there will be more projects for cooperation in the future.
HJ Kim
This is exactly what I was looking for. No, I mean EXACTLY. We are a company that designs lighting equipment,We have cooperated with FF tech for many years. Most of our electronic materials are purchased from here. We cooperate very well from proofing, trial production to mass production.
Steve Reischel
Our company has ordered ICs, connectors, switches and other electronic components from your company since 2017. After years of cooperation and consideration, the products you sell fully meet our requirements and our company's consideration of product quality.
Natalia Wolfson
We have long-term purchase of PCB boards from this company, perfect assortment for various projects, and a great value for the money. The soldered holes and pads are perfect, markings clear, and they’re all trimmed perfectly with no rough or uneven edges.
