Thermistors are a class of sensitive components, which are divided into PTC and NTC according to different temperature coefficients. PTC development history: appeared in 1950. In 1954, a PTC thermistor with barium titanate as its main material appeared. PTC thermistors are used in industry for tempe

Nowadays, the number of mobile phones supporting wireless charging is increasing, and most mobile phone manufacturers do not give away wireless chargers, resulting in a large demand for wireless chargers. At present, when manufacturing wireless chargers, NPO MLCC is more expensive, and the cost is v

Thermistor is typically characterized by temperature sensitivity and different resistance values at different temperatures. Positive Temperature Coefficient (PTC) has a higher resistance value at higher temperatures. Negative Temperature Coefficient (NTC) has a lower resistance value at higher tempe

CBB capacitor is non-inductive, polyester film is used as medium and aluminum foil for electrode winding, tinned copper clad steel wire, epoxy resin encapsulation; 1. CBB capacitor stability and reliability;2. No inductive structure reduces the loss factor to a low level;3. Excellent environmental p

In small appliances, the Y capacitor is one of the indispensable capacitors. The Y capacitor is used for common mode filtering. It is connected between L to ground or N to ground to filter out common mode signals from L to ground or N to ground. Y capacitors are usually used symmetrically, mainly fo

With the rapid development of microelectronics technology, digital control technology, communication and network technology and the wide application of CBB capacitors, intelligent, integrated, networked, high reliability, availability, maintainability, energy saving, and environmental protection hav

With the rapid development of China's auto market, car audio film capacitors are also developing rapidly. Audio equipment is an electronic product used in automobiles. It has evolved from a car radio to a comprehensive multimedia in-vehicle electronic system that integrates audio-visual entertainmen

Capacitors are an important part of many circuits and power equipment. Different requirements in the circuit and different capacitors are used, so capacitors can be divided into many different types. Can be divided according to material, structure, function, etc., and novices often mistake CBB and M

There are generally three types of overcurrent and overheating protection:1. Current overload: RL1 is the load curve during normal operation. When the load resistance value is reduced, such as the transformer circuit is short-circuited, the load curve changes from RL1 to RL2, exceeding point B, the

Nowadays, the electronic product market is developing rapidly, and people's demand for smart devices is also growing. It is also a process of the new and old cycle of China's film capacitors, from a low-end to a high-level product, from a simple product to a multi-product process. Domestic introduct
