Littelfuse 5 A Resettable Fuse 32V dc Radial Lead Orientation AHEF500

Littelfuse AHEF500 is a 5 A resettable fuse designed for automotive-grade and electronic circuit protection. The fuse operates at a DC voltage rating of 32V and features a radial lead orientation enabling easy PCB integration. Its compact size, with dimensions of 14mm length, 24.1mm height, and 3.8mm width, makes it suitable for high-volume electronics assembly.

This PolySwitch PPTC device provides maintenance-free protection by rapidly switching from a low resistance state to a high resistance state upon detecting electrical overload or short circuit. It automatically resets when the fault condition is cleared, eliminating the need for fuse replacement. Rated for a hold current of 5A and a trip current of 10A, it trips within 9 seconds to protect sensitive equipment effectively.

The fuse supports a wide operating temperature range from -40°C minimum to 60°C maximum, ensuring consistent performance in varied environments. Its low resistance characteristic (minimum 0.015Ω and maximum 40mΩ) coupled with a power dissipation of 5.3W adds to energy efficiency and safety.

It is designed specifically to meet automotive standards such as AEC-Q200 and conforms to RoHS regulations. Applications include telematics, infotainment, navigation systems, LCD back-light heaters, cigarette lighter outlets, motor circuits for power door-locks, mirrors, seats, sunroofs, and overcurrent protection in HVAC and cooling fan systems. It also finds use in security systems, power supplies, medical equipment, and telecommunications.

Automatically resets thousands of times without replacement. Eliminates maintenance needs and fuseholder requirements. Compliant with automotive and industry standards ensuring reliability. Compact radial lead design facilitates PCB mounting and assembly.

Effective protection for automotive and electronic electrical circuits. RoHS compliant enhancing environmental safety. Small size suitable for electronics with limited space. Maintains consistent hold and trip current ratings for protection accuracy.
