5×20 мм Брзо (Споро) Цијеви осигурачи са водовима

Тхе 520 fuse is a cylindrical glass or ceramic fuse tube with a diameter of 5mm and a length of 20mm. The rated voltage is usually 250V, and the current ranges from 0.1A to 30A.

There are two main types of 5*20 осигурачи: fast-blow type (Ф тип) and slow-blow type (Т тип). Fast-blow type is suitable for general electronic equipment, while slow-blow type is suitable for equipment with large starting current such as motors. The current specifications are very wide, ranging from the smallest 0.1A to the largest 30A.

Што се тиче сценарија примене, овај тип осигурача се широко користи у кућним апаратима, индустријска опрема, аутомобилска електроника и друге области. Параметри на које треба обратити пажњу приликом куповине укључују називну струју, називни напон, карактеристике спајања (брзо или споро), и стандарди сертификације (као што је УЛ, ЦСА, ВДЕ, итд.).

There are also different types of 5*20 fuse holders, such as direct plug-in type, waterproof type with leads, and PCB mounting type. Waterproof fuse holders are suitable for harsh environments such as outdoor lighting. The current carrying capacity of the fuse holder is usually 6-10A, and can reach up to 30A.

5*20 fuse is a standard size (5мм пречника, 20mm length) cylindrical circuit protection component, mainly used for overcurrent protection. The following is its core characteristics and application information:

Ја. Basic specifications and types
‌Size standard‌
Unified cylindrical design with a diameter of 5mm×length of 20mm, glass or ceramic package, and metal cap electrodes at both ends. ‌
‌Стаклена цев‌: transparent and visible, easy to observe the fuse status (common in low-voltage household appliances).
Керамичка цев: strong high temperature resistance, suitable for industrial environments. ‌

‌Current and voltage range‌
Називни напон: mainstream is 250V, and some models support 125V. ‌
Тренутни опсег: Covering ‌0.1A~30A‌, common segments include:
‌Small current‌ (≤1A): 0.1А, 0.2А, 0.25А, 0.5А, 1А (precision instruments, ЛЕД осветљење);
‌Medium and high current‌ (>1А): 2А, 3А, 5А, 10А, 15А, 20А, 30А (power supply equipment, мотор);

‌Fusing characteristics‌ ‌Fast-break type (Ф тип): Брзи одговор, suitable for sensitive electronic equipment (marked such as F1A, F5A). ‌
Тип спорог прекида (Т тип): Resistant to instantaneous current shock, погодан за моторе и трансформаторе (marked such as T2A, T10A). ‌

Ии. Key parameters and certifications ‌

Electrical performance‌ ‌Breaking capacity‌: 35A@250V (low current model) to 200A@250V (high current model), обезбеђивање безбедног искључивања у случају кратког споја. ‌
‌Прилагодљивост на температуру‌: Working temperature ‌-55℃~125℃‌, passed the hot and cold shock test (-40℃~90℃ cycle). ‌

‌Safety certification‌
Mainstream products have passed ‌UL, ЦСА, ЦЦЦ, ВДЕ, RoHS‌ certification and meet international safety standards. ‌

🛠️ III. Application scenarios and accessories ‌Typical applications‌
‌Кућни апарати‌: адаптер за напајање, small appliance circuit board (commonly used 1A~5A). ‌
Индустријска опрема: серво погон, модул за напајање (commonly used 10A~30A). ‌
‌Outdoor equipment‌: водоотпорни држач осигурача (ИП67 класа) for street lights and vehicle-mounted equipment. ‌

‌Одговарајући држач осигурача‌
‌ПЦБ тип инсталације‌: straight leg/bent leg design (such as PTF-77), supporting 10A~20A current. ‌
‌Waterproof lead type‌: with PVC sheath and nickel-plated brass terminals (као што је Х3-520Е), suitable for harsh environments. ‌

💡 IV. Purchase recommendations ‌Current matching‌
Select according to 1.5 times the maximum operating current of the circuit (на пример: the maximum current of the circuit is 2A → select a 3A fuse). ‌
‌Motor type‌: Prefer slow-break type (Т) to avoid false fuse at startup. ‌Digital circuit‌: Select fast-break type (Ф) to enhance overcurrent response. ‌
‌Certification and reliability‌
Confirm that the product has the ‌UL/CCC‌ mark to avoid uncertified brands (high safety risks). ‌

‌Purchase channels‌
Bulk purchase: Иакун Елецтроницс’ 1688 platform ($0.02/комад, 100 комада минимум) ‌
Retail replacement: Иакун Елецтроницс’ JD/Tmall (about $0.5 for 10 pieces). ‌

💎 Резиме
5*20 fuse is the basic protection component of electronic circuits. The selection needs to be based on current demand, fusing characteristics and environmental conditions. Give priority to brand products with complete certifications (such as Litte and Huade), and match them with corresponding fuse holders to ensure stable installation. ‌ For industrial or outdoor scenes, be sure to choose waterproof and high temperature resistant models to ensure long-term reliability.
