SMD fuse specifications | price - SMD fuses can be divided into SMD disposable fuses and SMD self recovery fuses. Among them, the specifications of patch disposable fuses include series 060312062410 fuses, and the specifications and dimensions of patch self recovery fuses include series 0603, 0805, 1206, 1210, 1812, 2920, etc. The price of SMD fuses varies depending on the type. The latest quotation for SMD fuses in the market is around a few cents, with wholesale prices. Good quality products can be sold for around one yuan. There are differences in prices between suppliers and traders, so when searching for products in bulk, it is more advantageous to find manufacturers and suppliers. Chip fuse specification | price - The fuse must be a fusible metal wire in order to fuse in a timely manner and provide protection when the current is high. The fuse material is mainly made of low melting point alloys such as aluminum antimony alloy. There are four basic forms of patch fuses: slo
With the development of life, electric vehicles have also become popular. In order to facilitate people's travel, many families have started to use electric vehicles, which are convenient and affordable. However, there are still many unknown problems that arise during use. Today, the editor will briefly talk about the structural issues of electric vehicles. Accidents involving spontaneous combustion or even explosions in electric vehicles occur from time to time. If the cause of external open flames is excluded, the only reason for electric vehicle fires is a short circuit. Any short circuit in the battery, charger, or other components will turn the electric vehicle into a powder keg! How to solve it? (Related knowledge: What is the relationship between fuse material and fuse failure?) Installing a "fuse or diode" for an electric vehicle is the simplest solution, as the fuse or diode serves as a short-circuit protection. Someone has conducted experiments on an electric vehicle wi
Traditional fuses are installed in circuits. When an overcurrent occurs due to a fault or abnormality in the circuit, the fuse itself melts to cut off the current and protect the circuit. However, due to the fact that traditional fuses can only protect once and need to be replaced if burned out, some products still cannot resume operation after troubleshooting or abnormal overcurrent disappears. As a new type of overcurrent protection device, the self recovery fuse has the function of automatic recovery, which can meet the performance requirements of similar applications. The self recovery fuse is connected in series in the circuit, and under normal circumstances, it is in a low resistance state to ensure the normal operation of the circuit; When a circuit experiences a short circuit or abnormally high current flows in, the self-heating of the self-healing fuse increases its impedance and limits the current to a sufficiently small amount, providing overcurrent protection. Self re
The fuses commonly used in PCB boards of small household appliances use self recovery fuses to protect the circuit. The selection of self recovery fuses in small household appliances can be divided into the following steps: Firstly, determine the working voltage of the self recovery fuse; 2. Based on the actual average operation of different products, determine whether the self recovery fuse is the inactive current; 3. The maximum current ratio, temperature, and other parameters of household small appliances in actual work, as well as the time required for self recovery fuse self correction (self recovery fuse action current amplification or reduction); 4. Revise it to an actual experiment and ensure that there is no false protection work, but it is necessary to self recover the fuse parameters within the specified time and protect the motor from stalling. The change in the thermistor of a small motor is an easy choice, but after repeated experiments, the thermal resistance of
Fuses have resistance values, but in fact, even wires have resistance. However, the resistance of the wires is very small (the nature of the conductor), which is usually ignored in general circuit calculations. However, the resistance of a fuse is significantly higher than that of an equally long wire, so that it can protect the circuit. The fuse is marked with "5A 250V", indicating that the maximum current allowed for Shenzhen fuses is 5A, which is called the rated current; The maximum voltage allowed to pass through is 250V, which is called the rated voltage. If the current or voltage exceeds the rated value, the fuse will blow, causing the circuit to open, thus protecting the consumer (without a fuse, the consumer may be burned out). The principle of fuse blowing is Joule's law. Joule's law: The heat generated by an electric current passing through a conductor is proportional to the square of the current, to the resistance of the conductor, and to the time it is energized. Jou
A fuse is a wire made of lead antimony alloy with a lower melting point and a lower resistivity. The more voltage constant resistance can be compared, the more it can detect micro current resistance that exceeds the working range. A high current is required to fuse the resistance, which can burn out the electrical appliance and prevent it from melting. Some principles use the current thermal effect fuse to control the current flow and allow the current to flow. According to the formula Q=IRT, the resistance produces more heat and is easier to fuse for safety and protection. It has a certain relationship with Joule's law, but things in life are not so simple. Fuses cannot be too large or small. If they are too large, they can easily burn down household wires and even cause fires. If they are too small, they can easily fuse and cause unnecessary trouble. A fuse can directly see the principle of a wire. The rated current of a fuse is the same as that of a wire. Even if it can be seen
