High Power Resistors (Fusible) Type FSQ Series Key Features � Protects Circuit Boards & Designs � Small Size � Excellent Long Term Stability � Complete Flame Proof Construction � Resistant to High Temperature � Low Temperature Coefficient � Uniform in Fusing Time There are some similarities between resistors and fuses in material and structure. Fusible Resistors contain both functions, as a resistor in normal conditions and as a fuse when abnormal currents are applied, so to protect machinery and equipment. Cost savings are apparent as one component is eliminated. The FSQ Fusible Resistor series are produced with precision techniques, enabling precise and stable fusing times. Characteristics - Electrical Operating Temperature (°C): -55 to +275 Resistance Temperature -30 to +150 ±300ppm/°C Coefficient (°C): Short Time Overload: 2.5 times of rated voltage for 5 seconds ΔR < ±2% Insulation Resistance: 500V Megger - 1000Mohms Temperature Cycle (°C): -30 to +85 for 5 cycles ΔR < ±1% Load Life: 70°C on-off cycle 1000 hours ΔR < ±5% Moisture-Proof Load Life: 40°C 95% RH on-off cycle 1000 hours ΔR < ±5% Solder Pot: 270°C for 3 seconds ΔR < ±1% Incombustability: 16 times of rated power for 5 minutes - Not Flamed Maximum Working Voltage: 1000 V Fusing Characteristics Fusing times can be decided by consultation with our design team to meet application requirements.
