Faced with a wide array of models available in the market, accurately selecting a suitable chip fuse for one's product is no easy task. Improper selection can lead to false fusing, affecting usage at the very least, and at worst, it can fail to provide effective protection, posing safety hazards. Therefore, it is imperative to systematically consider the following key points when selecting a chip fuse.
Simply put, the core difference between fast break and slow break patch fuses lies in their ability to withstand instantaneous overload currents. This determines that they are each suitable for vastly different circuit scenarios.
Under the same conditions of rated current and physical volume, the rated voltage value of fast-acting chip fuses tends to be higher than that of slow-acting ones. This is not accidental; it reflects a profound consideration of circuit protection characteristics.
Why is the 0402 disposable patch fuse only available in the fast break type? Uncover the design logic behind it.
Why do TWS earphones need 0402 patch fuses?
As an important component for circuit protection, SMD PTC Resettable Fuse plays a crucial role in electronic devices. Proper selection can not only effectively protect circuits from overcurrent and overheating damage, but also ensure long-term stable operation of equipment. This article will provide a detailed introduction to the six core elements that need to be considered when selecting disposable patch fuses, helping engineers make professional decisions.
The following is a systematic summary of the conventional packaging of disposable patch fuses:
The following is a classification of disposable patch fuse brand manufacturers based on global market and technological characteristics, combined with industry trends and product features:
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:
