Quick Blow Ceramic Package SMD Cartridge Fuse 4512 50A 72VDC 63VDC 32VDC For Battery Protection



DESCRIPTION


SMD fuses can be divided into disposable SMD fuses and SMD resettable fuses. After protection, the disposable fuse needs to be replaced, and the power failure after protection can be self-recovered and reused.

SMD fuse is a new product with high technical content in the small fuse industry. SMD fuses can be divided into SMD current fuses and SMD resettable fuses.

SMD current fuses can be divided into the following numbers according to their size and performance:

(1) Product size can be divided into: 0603 0805 1206 6125 1032 1245 4512

(2) Products can be divided into three types according to their properties: fast fusion, slow fusion and enhanced melting heat.

SMD resettable fuses can be classified by size as follows: SMD packages are 0805 0603 1206 1210 1812 2920 2018

If chip fuses have high requirements, they are usually made of thin films with ultra-low internal resistance and are suitable for overcurrent protection such as surges. Computer peripheral products, mobile phones and other communication equipment, digital cameras, monitors, and batteries are commonly used. Manufacturers who can use this technology have a certain scale.

SMD fuses can be divided into disposable SMD fuses and SMD resettable fuses. The disposable fuse needs to be replaced after protection, and the power failure after protection can be recovered and reused



Typical Application
