What are the categories of Haolilai fuses

Hollyland, as a leading enterprise in the field of circuit protection components, has a complete fuse product system that covers a wide range of application scenarios from micro to industrial levels. The following is a systematic analysis of the categories of Holiland fuses from four dimensions: product type, packaging form, functional characteristics, and application fields:
1、 Classified by product type
Tubular fuse
Structure: The metal melt is encapsulated in a tubular shell, with two designs: with and without leads.
Features: The lead type can be directly welded, while the non lead type requires the use of a fuse clamp/holder.
Applications: power adapters, chargers, industrial control equipment.
Radial lead fuse
Structure: The plastic shell wraps around the molten metal, and the leads are radially exported.
Features: Supports automatic or manual insertion, compact size, high breaking capacity.
Applications: consumer electronics, communication devices, small household appliances.
Surface mount fuses (SMD)
Structure:
Ceramic/resin matrix: printing metal melt, protective layer, and electrode.
Ultra miniature square tube: The end electrodes are coated with precious metals to enhance weldability.
Features: Suitable for reflow soldering process, lightweight and compact design.
Applications: Smartphones, wearable devices, precision instruments.
Power fuse
Structure: Combination of metal melt and tubular/irregular shell, with extremely strong breaking ability.
Characteristics: Resistant to high voltage and high current surges.
Applications: Photovoltaic inverters, power transmission and distribution equipment, industrial motors.
Self resetting fuse (PTC)
Material: High molecular weight polymer with positive temperature coefficient (PPTC) material is used.
