5×20 mm Cepat (Lambat) Tabung Sekering Dengan Timbal

Itu 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 sekering: fast-blow type (Tipe F) and slow-blow type (Tipe T). 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.

Mengenai skenario aplikasi, Sekering jenis ini banyak digunakan pada peralatan rumah tangga, peralatan industri, elektronik otomotif dan bidang lainnya. Parameter yang perlu diperhatikan saat membeli antara lain arus pengenal, tegangan pengenal, karakteristik sekering (cepat atau lambat), dan standar sertifikasi (seperti UL, CSA, VDE, dll.).

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

SAYA. 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. ‌
‌Tabung kaca‌: transparent and visible, easy to observe the fuse status (common in low-voltage household appliances).
‌Tabung keramik‌: strong high temperature resistance, suitable for industrial environments. ‌

‌Current and voltage range‌
‌Tegangan terukur‌: mainstream is 250V, and some models support 125V. ‌
‌Rentang saat ini‌: Covering ‌0.1A~30A‌, common segments include:
‌Small current‌ (≤1A): 0.1A, 0.2A, 0.25A, 0.5A, 1A (precision instruments, pencahayaan LED);
‌Medium and high current‌ (>1A): 2A, 3A, 5A, 10A, 15A, 20A, 30A (power supply equipment, motor);

‌Fusing characteristics‌ ‌Fast-break type (Tipe F): Respon cepat, suitable for sensitive electronic equipment (marked such as F1A, F5A). ‌
‌Jenis istirahat lambat (Tipe T): Resistant to instantaneous current shock, cocok untuk motor dan trafo (marked such as T2A, T10A). ‌

II. Key parameters and certifications ‌

Electrical performance‌ ‌Breaking capacity‌: 35A@250V (low current model) to 200A@250V (high current model), memastikan pemutusan sambungan yang aman jika terjadi korsleting. ‌
‌Kemampuan beradaptasi terhadap suhu‌: Working temperature ‌-55℃~125℃‌, passed the hot and cold shock test (-40℃~90℃ cycle). ‌

‌Safety certification‌
Mainstream products have passed ‌UL, CSA, CCC, VDE, RoHS‌ certification and meet international safety standards. ‌

🛠️ III. Application scenarios and accessories ‌Typical applications‌
peralatan Rumah Tangga: power adapter, small appliance circuit board (commonly used 1A~5A). ‌
‌Peralatan industri‌: penggerak servo, modul daya (commonly used 10A~30A). ‌
‌Outdoor equipment‌: dudukan sekering tahan air (kelas IP67) for street lights and vehicle-mounted equipment. ‌

‌Pemegang sekring yang cocok‌
‌Jenis pemasangan PCB‌: straight leg/bent leg design (such as PTF-77), supporting 10A~20A current. ‌
‌Waterproof lead type‌: with PVC sheath and nickel-plated brass terminals (seperti H3-520E), suitable for harsh environments. ‌

💡 IV. Purchase recommendations ‌Current matching‌
Select according to 1.5 times the maximum operating current of the circuit (Misalnya: the maximum current of the circuit is 2A → select a 3A fuse). ‌
‌Motor type‌: Prefer slow-break type (T) to avoid false fuse at startup. ‌Digital circuit‌: Select fast-break type (F) 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: Yaxun Elektronik’ 1688 platform ($0.02/bagian, 100 potongan minimal) ‌
Retail replacement: Yaxun Elektronik’ JD/Tmall (about $0.5 for 10 bagian-bagian). ‌

💎 Ringkasan
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.
