Fuses with Leads (Through Hole) are designed for easy installation on printed circuit boards (PCBs). These fuses incorporate leads that pass through holes in the PCB, allowing for secure and reliable connection. Serving as protective devices, they interrupt the circuit in case of overcurrent or short circuit conditions, safeguarding electronic components from damage. The cost of through-hole fuses depends on factors like current rating, voltage, and application. Standard ones for common electronic circuits are affordable, suitable for a wide range of uses. Specialized or high-current fuses with specific features may cost more. When buying, ensure compatibility with your PCB design, considering current, voltage, and protection type. Evaluate additional features like arc flash protection if needed. Adhere to safety standards and consider size and mounting requirements for effective circuit protection and component longevity.
