　　To fully utilize the protective effect of a fuse in a circuit, the position of the fuse in the circuit should be considered when designing the circuit.

　　The fuse can be blown in a timely manner to protect the circuit and switch;

　　And the fuse cannot be blown in a timely manner, unable to protect the front-end circuit and switch. If a short circuit occurs at B, the fuse can only be blown in a timely manner, which can protect the circuit;

　　As shown in the circuit diagram, when a short circuit occurs at point A, the switch will still burn out, while the fuse will not blow, meaning that the fuse in this circuit cannot protect the circuit and electrical components. So the circuit diagram is the most reasonable one for designing the position of the fuse in the circuit.

　　Note: For the case where relays and fuses are integrated in the same electrical box, the fuse connection is not closely related (as the possibility of a short circuit occurring within the same electrical box is not high), otherwise the most reasonable connection is as shown in the diagram.

mini blade fuse Vendor.What tips should be paid attention to when selecting SMD fuses

　　　　Chip fuse is a relatively high-tech new variety in the small fuse industry. Chip fuse can be divided into disposable chip fuse and chip self recovery fuse. Disposable chip fuse, also known as chip current fuse, needs to be replaced after protection, and after self recovery fuse protection, power is cut off, it can be restored on its own and can be reused.　　The disposable patch current fuses can be divided into the following models based on size and performance:　　(1) According to size, products can be divided into: 0402, 0603, 1206241061251032.　　(2) According to performance, products can be divided into three types: fast melting, slow melting, and enhanced melting heat energy. The SMD fuse quick blow series is suitable for protecting important components that quickly respond in circuits, and is generally used in situations where surge currents rarely occur; The slow fuse series is suitable for situations where large surge currents often occur in circuits; The enhanced melting heat e

What are the drawbacks of LED Fuses driver power supply.microwave high voltage fuse blown

　　　　What are the drawbacks of LED driver power? With the development of LED applications, LED driver power has also been widely used. Last week, we talked about the development trend of LED driver power. Today, the editor will briefly explain the shortcomings of LED driver power.　　Firstly, the technical personnel of companies that produce LED lighting and related products do not have sufficient understanding of switching power supplies. The power supplies produced can work normally, but some critical evaluations and electromagnetic compatibility considerations are not sufficient, and there are still certain hidden dangers; (Related knowledge: The development trend of LED power drive)　　Secondly, most LED power supply manufacturers have transitioned from ordinary switching power supplies to LED power supplies, and their understanding of the characteristics and use of LEDs is not yet sufficient;　　However, currently there are almost no standards for LEDs, most of which refer to the standar

　　　　1. Rated zero power resistance　　PPTC thermistors should be packaged according to zero power resistance levels, and the resistance range should be indicated on the outer packaging. After the withstand voltage and current resistance tests, the change rate of the resistance before each group of samples is extremely poor δ| After Ri - Before Ri - (After Rj - Before Rj)/Before Rj | ≤ 100%　　2. PTC effect　　A material has a PTC (Positive Temperature Coefficient) effect, which means that the resistance of the material increases with increasing temperature. Most metal materials have the PTC effect. In these materials, the PTC effect is manifested as a linear increase in resistance with increasing temperature, which is commonly referred to as the linear PTC effect.　　3. Nonlinear PTC effect　　The material undergoing phase transformation will exhibit a phenomenon where the resistance rapidly increases by several to more than ten orders of magnitude along a narrow temperature range, known as the

surface mount fuse manufacturer.Selection Techniques for Chip Fuses

　　　　Firstly, normal current: Firstly, we must know the fuse that flows through the circuit chip used in normal current. Usually, we need to reduce the difference between the predetermined amount and then follow the selection principle: the normal current must be less than the rated current and the product's derating factor.　　Secondly, the fusing current: According to UL standards, Shenzhen patch fuses (fuses) should be able to quickly operate at twice the rated current. But in most cases, to ensure reliable fuses, we recommend that the fusing current be greater than 2.5 times the rated current. In addition, the fusing time is very important, and a judgment must also be made based on the manufacturer's fusing characteristics.　　Thirdly, short-circuit current: the maximum current value, when we call it the short-circuit current of a short circuit. The rated breaking capacity of various fuses is necessary, and we must be careful not to choose fuses with circuit currents exceeding the rated

Three major factors affecting the lifespan of fuses.max fuse size meaning

　　　　1. Working environment temperature: Excessive ambient temperature can damage the lifespan of fuses. Slow melting fuses, such as tin ball type, begin to diffuse towards the metal wire when the temperature is about 160 ℃ (150-170 ℃); The temperature at which the melt of a fast melting fuse begins to undergo severe oxidation is approximately 200 ℃ (175-225 ℃). With the oxidation of the fuse from the outside to the inside, multiple diffusion, thermal stress fatigue, etc., the lifespan of the fuse will gradually shorten. Therefore, it is recommended that the delay type fuse fuse should not work above 150 ℃ for a long time, and the fast melting type fuse should not work above 175~225 ℃ for a long time.　　2. Pulse current: Pulse impact can generate thermal cycling, leading to diffusion, oxidation, thermal stress, and even acceleration of the fuse. The fuse will gradually age with increasing pulse energy and frequency. The impact resistance life of a fuse depends on the percentage of I2t of
