PTC thermistor is a sensitive element. The resistance value of the thermistor changes with temperature. Unlike general-purpose fixed resistors, it is a type of variable resistor widely used in various electronic components. Unlike resistance thermometers

The traditional disposable fuse as an overcurrent protection element can only be protected once, and needs to be replaced after the fuse. Due to its self-recoverable nature, polymer self-recovery fuses can be installed and reused at a time. As a new type

SMD fuses are mainly used in digital cameras, notebooks, mobile phones and other electronic products, from traditional glass tube fuses to small fuses and SMD fuses. Due to differences in product technology, the focus of their selection is slightly differ

Now the fuses are getting smaller and smaller, so most manufacturers will study how to produce smaller fuses. Among the small fuses, chip fuses are one of them, and they are a better fuse. Most people will buy this type during the purchase process, becaus

Both PTC thermistor and NTC thermistor are thermistors. According to different temperature coefficients, it is divided into positive temperature coefficient thermistor (PTC) and negative temperature coefficient thermistor (NTC). The positive temperature c

Working principle of ptc thermistor: The ptc thermistor will be in an inactive state for a long time; when the ambient temperature and current are in the c zone, the heat dissipation power of the thermistor is close to the heating power, so it may

The working principle of PPTC resettable fuse is the dynamic balance of energy. Due to the PPTC relationship, the current flowing through the PPTC components generates heat, and the generated heat is completely or partially discharged into the environment

The selection of pptc self-recovery fuses has always been a problem that plagues many people. So from what aspects should the selection of pptc self-recovery fuses start? What is the meaning of the parameters of pptc self-recovery fuse? The followi

Everyone will always see some names about chip fuses on chip fuses. In fact, these are all terms about chip fuses, so what do these terms mean? 1. Voltage rating: The voltage rating of the fuse is a value compared with the voltage in the cir

The pptc self-recovery fuse has become more and more popular, so what problems should be paid attention to when selecting the pptc self-recovery fuse? 1. Normal working voltage of pptc self-recovery fuse First of all, we need to understand

Self-recovery fuses can be divided into patch self-recovery fuses and plug-in self-recovery fuses. With the increasing miniaturization of product requirements, the application planning of chip fuses has become more and more extensive. The self-recovery fu
