  • SEMIFUSE SFLR RESETTABLE BATTERY STRAP PTC Fuse

    Semifuse SFLR PPTC fuses are ideal for high-power battery applications, providing reliable non-cycling protection against over-charging and short-circuits. With a lower resistance and a smaller mass, they provide faster trip times and improved battery protection.

    • Current ratings: 1.9A – 9.0A
    • Voltages between 15V – 20V (DC)
    • Temperature between -40°C to +85°C
    • Nickel straps for spot welding directly onto battery cells
  • SEMIFUSE SFLT BATTERY STRAP RESETTABLE PTC Fuse

    Semifuse SFLT resettable PPTC fuses offer improved battery protection, particularly in low-power battery applications. These PTC strap fuses provide reliable non-cycling protection against over-charging and short-circuits. By switching at lower temperatures, they have faster trip times, making them ideal for the latest generation of battery designs.

    • Current ratings: 0.7A – 3.4A
    • Voltage 24V (DC)
    • Temperature between: -40°C to +60°C
    • Nickel straps for spot welding directly onto battery cells
  • SEMIFUSE SFVT ULTRA SLIM BATTERY STRAP PTC Fuse

    Semifuse SFVT resettable PPTC  fuses are ideal for Li-ion battery protection.

    These are ultra-slim and have a 20% lower temperature trip compared to our standard series. They offer protection against over current and over temperature conditions.

    • Current ratings: 1.1A – 2.4A
    • Voltages 16V (DC)
    • Temperature between: -40°C to +60°C
    • Nickel straps for spot welding directly onto battery cells
  • SEMIFUSE SFR60F 60V RADIAL LEADED PTC Fuse
