The Role of Film Capacitors in Filtering Circuits
There are many types and models of capacitors, and film capacitors are one of the them. Film capacitors have the characteristics of non-polarity, high insulation resistance, high voltage resistance, wide operating temperature range, and good self-healing properties, which are widely used in the e...Read more -
Why Are Supercapacitors Used in Car Dash Cam
The dash camera installed in the car can record the video image and sound of the whole driving process of the car, and when encountering a traffic accident, it can provide valid evidence to assist in handling the accident. In addition, the dash camera can be connected to the direct power supply t...Read more -
The Film Capacitor in Electric Toothbrush
Electric toothbrushes are much more convenient than regular toothbrushes. The frequency of manual tooth brushing is about 100-200 times/minute, while the frequency of electric toothbrushes is about 30,000-40,000 times/minute, which is a hundred times faster than manual toothbrushing, so it is cle...Read more -
Can Y Capacitor and Ceramic Capacitor Replace Each Other
There are varied types of capacitors. Although electronic components are divided into different components according to structure and function, some electronic components look similar in appearance, such as safety Y capacitors and ceramic capacitors. They are similar in appearance, and are both i...Read more -
Thermistor Used in Electric Heating Uniform
Thermistors are a type of sensitive components, which are divided into positive temperature coefficient thermistors (PTC) and negative temperature coefficient thermistors (NTC) according to different temperature coefficients. NTC thermistors are used in different fields, so what is the applicatio...Read more -
Do Supercapacitors Smaller Than a Grain of Dust Really Exist
