Littelfuse, Inc., an industrial technology manufacturing company, announced the release of the 828 and 827 Series High-voltage Cartridge Fuses.
Designed to meet the unique needs of electric vehicle (EV) systems, these fuses are the first AEC-Q200-compliant cartridge fuses rated at 1,000 Vdc (828 Series) and 800 Vdc (827 Series).
Their compact, automotive-grade design delivers reliable circuit protection for high-voltage EV subsystems such as onboard chargers (OBCs) and power distribution units (PDUs). The 828 and 827 Series offer a 10-kA interrupting rating, a wide operating temperature range (-55° to 125° C), and multiple mounting configurations (through-hole and bolt-down).
These features provide engineers with flexible, space-saving solutions for integrating protection into next-generation EV power electronics.
Key differentiators include:
- Voltage ratings: 1,000 Vdc (828 Series) / 800 Vdc (827 Series)
- Interrupting capability: 10 kA at rated voltage (both series)
- Mounting flexibility: Through-hole and bolt-down versions with integrated ISO terminal and stand-off leads
- Standards compliance: AEC-Q200, RoHS, Halogen Free, and 100% Pb-Free
By eliminating the need for additional mounting accessories or complex lead-forming processes, these fuses simplify integration into high-voltage circuits while maximizing PCB real estate efficiency.
Their reliable construction ensures performance and durability in harsh environments, which is mission-critical for EV applications.
The 828 and 827 Series expand Littelfuse’s portfolio of circuit protection solutions for the rapidly evolving el-mobility market. By combining high voltage ratings with automotive-grade reliability and flexible assembly options, these fuses enable engineers to develop safer and more efficient EV power systems.
The 828/827 Series Fuses are available in tray format in quantities of 300 to 500.
Applications:
- EV electronics
- OBCs
- PDUs
- High-voltage EV subsystems
