5×20 मिमी फास्ट (धीमा) लीड के साथ ट्यूब फ़्यूज़

The 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 फ़्यूज़: fast-blow type (एफ प्रकार) and slow-blow type (टी प्रकार). 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.

आवेदन परिदृश्यों के बारे में, इस प्रकार के फ्यूज का व्यापक रूप से घरेलू उपकरणों में उपयोग किया जाता है, औद्योगिक उपस्कर, मोटर वाहन इलेक्ट्रॉनिक्स और अन्य क्षेत्र. खरीदारी करते समय जिन मापदंडों पर ध्यान देने की आवश्यकता होती है, उनमें रेटेड करंट शामिल होता है, रेटेड वोल्टेज, फ्यूज़िंग विशेषताओं (तेज या धीमी गति से), और प्रमाणन मानकों (जैसे उल, सीएसए, वीडीई, वगैरह।).

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 (5मिमी व्यास, 20mm length) cylindrical circuit protection component, mainly used for overcurrent protection. The following is its core characteristics and application information:

मैं. 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. ‌
‌ग्लास ट्यूब: transparent and visible, easy to observe the fuse status (common in low-voltage household appliances).
‌सिरेमिक ट्यूब: strong high temperature resistance, suitable for industrial environments. ‌

‌Current and voltage range‌
रेटेड वोल्टेज: mainstream is 250V, and some models support 125V. ‌
‌वर्तमान सीमा: Covering ‌0.1A~30A‌, common segments include:
‌Small current‌ (≤1A): 0.1ए, 0.2ए, 0.25ए, 0.5ए, 1ए (precision instruments, प्रकाश नेतृत्व);
‌Medium and high current‌ (>1ए): 2ए, 3ए, 5ए, 10ए, 15ए, 20ए, 30ए (power supply equipment, मोटर);

‌Fusing characteristics‌ ‌Fast-break type (एफ प्रकार): त्वरित प्रतिक्रिया, suitable for sensitive electronic equipment (marked such as F1A, F5A). ‌
‌धीमे-ब्रेक प्रकार (टी प्रकार): Resistant to instantaneous current shock, मोटर और ट्रांसफार्मर के लिए उपयुक्त (marked such as T2A, T10A). ‌

द्वितीय. Key parameters and certifications ‌

Electrical performance‌ ‌Breaking capacity‌: 35A@250V (low current model) to 200A@250V (high current model), शॉर्ट सर्किट की स्थिति में सुरक्षित वियोग सुनिश्चित करना. ‌
‌तापमान अनुकूलनशीलता: Working temperature ‌-55℃~125℃‌, passed the hot and cold shock test (-40℃~90℃ cycle). ‌

‌Safety certification‌
Mainstream products have passed ‌UL, सीएसए, सीसीसी, वीडीई, RoHS‌ certification and meet international safety standards. ‌

🛠️ III. Application scenarios and accessories ‌Typical applications‌
घर का सामान: बिजली अनुकूलक, small appliance circuit board (commonly used 1A~5A). ‌
‌औद्योगिक उपकरण‌: सर्वो ड्राइव, पावर मॉड्यूल (commonly used 10A~30A). ‌
‌Outdoor equipment‌: जलरोधक फ्यूज धारक (IP67 ग्रेड) for street lights and vehicle-mounted equipment. ‌

‌मिलान फ़्यूज़ धारक
पीसीबी स्थापना प्रकार: straight leg/bent leg design (such as PTF-77), supporting 10A~20A current. ‌
‌Waterproof lead type‌: with PVC sheath and nickel-plated brass terminals (जैसे H3-520E), suitable for harsh environments. ‌

💡 IV. Purchase recommendations ‌Current matching‌
Select according to 1.5 times the maximum operating current of the circuit (उदाहरण के लिए: the maximum current of the circuit is 2A → select a 3A fuse). ‌
‌Motor type‌: Prefer slow-break type (टी) to avoid false fuse at startup. ‌Digital circuit‌: Select fast-break type (एफ) 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: याक्सुन इलेक्ट्रॉनिक्स’ 1688 platform ($0.02/टुकड़ा, 100 टुकड़े न्यूनतम) ‌
Retail replacement: याक्सुन इलेक्ट्रॉनिक्स’ JD/Tmall (के बारे में $0.5 for 10 pieces). ‌

💎सारांश
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.
