Specification Brand : Heyiarbeit BulletPoint1 : 【Dimension】- Length: 20mm/0.78"; Diameter: 5mm/0.20" BulletPoint2 : 【Function】-The slow-blow fuse is also called a time-delay fuse. Its delay characteristic is maintained in the circuit when it has a non-fault pulse current and can protect against long-term overload. BulletPoint3 : 【Advantage】- Slow acting fuse, resist surge current, fit for charger monitoring equipment and circuit protection of mini transformer. BulletPoint4 : 【Application】- Suitable for various type of electronic equipment circuit over-current protection, widely used in energy-saving lights, electronic ballasts, telecommunications and other consumer electronic equipment. BulletPoint5 : 【Package content】- 20pcs x Glass Tube Fuses Color : silver ExternallyAssignedProductIdentifier1 : 0703110315223 ExternallyAssignedProductIdentifier2 : 703110315223 ItemName : Heyiarbeit Glass Tube Fuses Axial with Lead Wire Slow-Blow Time-lag Fuses 5x20mm 20A 250V for Replacing or Repairing Many Home Electronics 20Pcs (T20A) ItemPackageDimensions_Height : 11.2 centimeters ItemPackageDimensions_Length : 3.3 centimeters ItemPackageDimensions_Width : 8.3 centimeters ItemPackageQuantity : 1 ItemTypeKeyword : cartridge-fuses Manufacturer : Heyiarbeit Material : Glass MaximumCurrent : 20 amps ModelNumber : DFB4701HF0220 MountingType : Surface Mount NumberOfItems : 1 PartNumber : DFB4701HF0220 ProductDescription : Description: 1. A type of low resistance resistor that acts as a sacrificial device to provide over-current protection, of either the load or source circuit. 2.The melt of the time-delay fuse is specially processed to absorb energy. By adjusting the energy absorption, it can resist the inrush current and protect the overload. 3.Glass fuse is mainly used in vehicle and ship accessories, household appliances and consumer electronic products, such as microwave oven, fan, TV, circuit board, lighting, instrument, etc 4.Used for protecting the electrical circuit against overload and short circuit, it also derive for protecting the semiconductor objects.
