| 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 x 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.
