The terminal electrodes of patch fuses are usually treated with multi-layer electroplating technology. Gold plating and silver plating are two high-performance surface treatment schemes, and their differences are mainly reflected in material characteristics, application scenarios, and costs
Although the structure of disposable surface mount fuses (also known as surface mount fuses) is compact, the material selection is crucial for performance and reliability. The material composition mainly revolves around the following core parts:
The conventional volume of disposable patch fuses is mainly divided based on their packaging size, with common packaging sizes including 0402, 0603, 0805, 1206, 1210, 1812, 2010, 2012, 2016, 2410, 2412, 2512, 2920, etc. These package sizes are typically represented as four digits, with the first two digits representing length and the last two digits representing width, measured in hundredths of an inch (i.e. 1/100 inch). The following is a detailed introduction to some common packaging sizes of disposable patch fuses:
As the core component of circuit protection, disposable fuses are classified into six dimensions: packaging form, current range, voltage level, material type, melting speed, and special functions. The following is a detailed classification and characteristic analysis:
The existence of disposable fuses and self-healing fuses stems from their different working principles, application scenarios, and respective advantages and disadvantages. The following is a detailed introduction:
The Walter 6125SF series fuse is a disposable quick break fuse with current and voltage limiting functions, which can be used to protect circuits from overcurrent damage. Its packaging specification is 6.1 * 2.5, with a rated current of 1.0A~20A. This type of fuse has a fast melting characteristic and can respond to short circuit or overcurrent faults in a timely manner, thereby protecting the safety of circuits and equipment.
The Sart high current SMT fuse 1032-F series is a disposable SMT fuse, mainly characterized by high current, high voltage, and a wide range of rated current options. It is widely used in various power sources and energy storage power management systems. This article provides a detailed introduction to the main product selection parameters and model list of the Sart 1032 high current SMT fuse.
Introduction to Sart's 1245 series NANO SMT fuses with high current and high breaking. The Sat 1245 fuse belongs to the NANO high current patch type disposable fuse. The rated current can reach 60A (amperes), and the breaking capacity can reach 1000A@72V DC, and has passed UL safety certification with UL safety certification number E319512. This article introduces the detailed electrical performance parameters of the 1245 series NANO fuse.
Detailed introduction to the parameters of Sart NANO SMT fuse 6125-F series products. The Sart NANO patch type disposable fuse 6125-F belongs to the terminal gold-plated quick break SMD fuse. This series has high current, high voltage resistance, and extremely high product reliability, and is widely used in products such as battery boards and power modules. This article provides a detailed introduction to the product selection table and product parameters of the Sart 6125-F series.
The Sart high surge resistant patch fuse 6125-H series is a brass gold-plated NANO patch type disposable fuse. The use of brass gold-plated technology gives the product higher conductivity, drought resistance, and high temperature curves. The rated current range of the 6125-H series is 0.5A~5A, and the rated voltage is 125V AC/DC. This article provides a detailed introduction to the product selection parameters and model list of Sart's 6125-H series of high wave resistant SMT fuses.
