TOKEN FRN, FKN, FSQ Fusible Resistors Fusible Resistors Fusible Resistors - FRN, FKN, FSQ Series Fusible Resistor Features Best of Both Worlds Preview Designers of small power supplies and battery chargers for consumer products can benefit from a fusible resistor with superior lightning strike and pulse abilities in a cost effective package. Token Electronics offers a combination resistor/fuses series of metal/carbon film fusbile resistor (FRN), wirewound fusbile resistor (FKN) and cement encased fusbile resistors (FSQ). Token offers fusbile FRN series a low-cost alternative to traditional solutions for applications that require surge protection. The robust cement-coated wire-wound FSQ resistors and wirewound fusbile FKN resistors are ideal for power supply applications across the telecomms, military and industrial markets which require a replacement for carbon composition resistors within the circuit design. As part of the Token input protection range, this resistor provides a key fusible solution and is completely customisable to suit the individual application design requirements. Key design engineers with a need for a robust resistor, will find the FRN, FKN and FSQ series are a multifaceted product, providing comparable pulse performance with added fusing capabilities. Our custom solutions are designed to address your need for technical and economic success in a timely manner. Contact us with your specific needs.

The power can be calculated: Power = Amperes 2 × Ohms Fusing Device Application Notes ● When using, it shall be made sure that the overload conditions at unusual moments lie within the fusing territory. ● Consult with Token in advance when overloaded higher than the rated voltage under an ordinary situation since such an overload may store up damages on resistors. ● Use at the maximum open-circuit voltage or lower as an arc phenomenon may arise when high voltage is applied again after fusing by an over current. ● Consult with us for the maximum open- circuit voltage because it varies with applications.
