　　Fuse selection is a step that circuit design engineers must be cautious about. If the protective components of the circuit are not selected properly, the entire process of powering on the circuit will be affected, and the normal use of the product will also be affected. So today, let's learn about the ten key points of fuse selection:

　　Key points for fuse selection: rated current;

　　Key points for fuse selection 2: rated voltage;

　　Key points for fuse selection: environmental temperature;

　　Key points for fuse selection: voltage drop/cold resistance;

　　Key points for fuse selection: fusing characteristics: overload capacity, time/current characteristics;

　　Key point six for fuse selection: breaking capacity;

　　Key point seven for fuse selection: melting heat value;

　　Key points for fuse selection: durability (service life);

　　Key points for fuse selection nine: structural features: appearance/size, installation form;

　　Key points for fuse selection: safety certification.

　　　　Application of Self Recovery Fuse in RS485 Communication Port Lightning Protection　　RS485, as one of the most commonly used serial differential communication methods in the industry, adopts a balanced transmission and differential reception method, which has the ability to suppress common mode interference. Due to its long communication distance (over 1200m), high transmission rate (10Mbps), high signal-to-noise ratio, convenient control, low cost, and the ability to achieve multiple nodes on a single bus, as well as the variety of transceivers that can be used, RS485 has the advantages of being able to suppress common mode interference, It has been increasingly recognized by users.　　However, with the increase in usage frequency, the problems encountered are also increasing day by day. Due to the fact that RS485 communication transmission lines are usually exposed outdoors, lightning and electrostatic interference have become common problems in practical engineering of RS485 commun

　　　　The full name of 3C certification is "Compulsory Product Certification System", which is a product qualification evaluation system implemented by the Chinese government in accordance with laws and regulations to protect consumer personal and national safety, strengthen product quality management, and implement it. The so-called 3C certification is the China Compulsory Certificate system. It should be noted that the 3C mark is not a quality mark, but rather a fundamental safety certification.　　The "CCC" certification mark is divided into four categories　　The current "CCC" certification mark is divided into four categories, namely:　　1. CCC+S safety certification mark;　　2. CCC+EMC electromagnetic compatibility certification mark;　　3. CCC+S&E safety and electromagnetic compatibility certification mark;　　4. CCC+F fire certification mark;　　China has implemented the National Compulsory Certification System (CCC) since May 1, 2002. Compulsory certification is implemented for produc

How to Choose the Rated Voltage and Current of Chip Fuses.30 amp screw in resettable fuse

　　　　How to choose the rated voltage and current of a patch fuse: The rated voltage of a patch fuse depends on the current flowing through it, and is not related to the working voltage of the circuit. From the perspective of safe use, the rated voltage of SMD fuse is proposed, which is the highest working voltage of the circuit when the SMD fuse is in a safe working state. This means that fuses can only be placed in circuits with a working voltage less than or equal to the rated voltage of the fuse. Only in this way can the fuse operate safely and effectively.　　The voltage drop at both ends of the patch fuse is very small, much lower than the rated voltage of the patch fuse. Therefore, during normal operation, the rated voltage has no practical significance. The true significance of the rated voltage of patch fuses lies in their safety performance. Chip fuse, as a safety component, must be relatively safe during normal operation, protective action, and any time period after melting. The

The difference between fuse and circuit breaker.battery fuse blown symptoms

　　　　The same thing is that both can achieve short-circuit protection. The principle of a fuse is to use current to flow through the conductor, causing it to heat up. After reaching the melting point of the conductor, the conductor melts, so disconnecting the circuit protects the electrical appliances and circuits from being burned out. It is an accumulation of heat, so overload protection can also be achieved. Once the melt burns out, it needs to be replaced.　　A circuit breaker can also achieve short-circuit and overload protection for circuits, but the principle is different. It achieves circuit breaker protection through the bottom magnetic effect of the current (electromagnetic release), and overload protection through the thermal effect of the current (not fusing, and there is often no need to replace components). In practice, when the electrical load in the circuit approaches the load of the fuse used for a long time, the fuse will gradually heat up until it blows. As mentioned ab

　　　　1. Voltage Ratings:　　The voltage rating of the fuse must be greater than or equal to the high voltage of the disconnected circuit. Due to the very low resistance of the fuse, the voltage rating of the fuse becomes important only when the fuse attempts to blow. After the fuse element melts, the fuse must be able to quickly disconnect, extinguish the arc, and prevent the open circuit voltage from triggering the arc again through the disconnected fuse element.　　2. Current Ratings:　　The current rating indicates the current carrying capacity of the fuse under a set of test conditions. Each fuse will indicate the current rating, which can be marked with numbers, letters, or colors. The meaning of each marker can be found through the product data table.　　3. Breaking Capacity/Interrupting Rating:　　The fuse must be able to disconnect the faulty circuit without damaging the surrounding circuit. Breaking capacity refers to the current value at which a fuse can safely open a circuit without da
