There are some similarities between Resistors and Fuses in material and structure. Fusible Resistors contain both functions, as being resistor in normal condition and changed into fuse while abnormal current comes in to protect machine and equipment. Since two functions performed by one resistor, the cost therefore saved. TY-OHM FKN & FSQ Fusible Resistor series are produced with precision technique, enabling precise fusing time and stabilized, aiming to reach best quality resistors.
Features
- It is suitable for protecting circuit boards and design.
- Small in size with competitive price.
- Noncombusible insulating coat. "Solvent" proof and resistant to high temperature.
- Low temperature coefficient.
- Uniform in fusing time.
