Electrical, Specialty Fuses
1. What are Electrical, Specialty Fuses?
Specialty Fuses: A type of device that achieves overcurrent/overvoltage protection through a fusing mechanism, which can be divided into traditional fusing types (such as glass tube fuses and chip fuses) and electronic fuses (eFuse).
Electronic fuse (eFuse): A programmable electronic fuse that achieves fusing based on thermal effects or electron injection, with non-volatile storage characteristics, suitable for chip calibration, power management, and anti-tampering scenarios.
2. What are the Core Parameters of Electrical, Specialty Fuses?
Limit Parameters: including maximum operating voltage (V_max), rated current (I_rated), fusing time (T_fusing), etc., which must be strictly followed to avoid device damage.
Dynamic Characteristics: such as overload recovery capability (resettable fuse), fusing accuracy (error range), and temperature sensitivity (thermal fuse).
3. Where are Electrical, Specialty Fuses Used?
Circuit Protection: Prevent permanent damage to power supplies, chips, or other sensitive components caused by overcurrent/short circuits.
System Calibration: eFuse is used to store chip calibration parameters (such as voltage threshold, and clock frequency) to improve system stability and energy efficiency.
Safety Protection: Implement safety designs such as lightning protection and anti-static in industrial equipment and communication systems.
4. Technology Development Trends of Electrical, Specialty Fuses
Intelligence: eFuse with an integrated digital control interface supports real-time status monitoring and remote configuration.
Miniaturization: SMD fuses and integrated eFuse meet the needs of high-density PCB design.
