Wirewound Fusiable Resistor

FKN Operates as a resistor under normal conditions but acts as a fuse under excessive loads,FKN

Operates as a resistor under normal conditions but acts as a fuse under excessive loads,FKN

Description

Wirewound fusible resistors act as both a precision current-limiting resistor and a protective fuse, designed to safely open a circuit during overloads, surges, or faults without flame or explosion. These components, often found in power supplies and appliances, are characterized by high reliability, surge handling capabilities, and nonflammable construction.

  • Characteristics:
  1. Operates as a resistor under normal conditions but acts as a fuse under excessive loads.
  2. Power: 0.5W up to 7W (or higher).

  • Applications:
  1. Power Supplies,Chargers: Used as input protection.
  2. Household Appliances: Provides inrush pulse protection.
  3. Automotive Electronics: Used in battery management systems (BMS) and ECU systems.
  4. Industrial Control: Protects motor drives and PLC systems
