Offline Flyback Converter Short Circuit Protection Bourns PortNote solutions provide protection recommendations for typical port threats. Solution Products Objective e PTh PTC resettable fuse protects the diode and e oTh bjective of this PortNote Solution is the transformer during transient overloading the low-cost overload protection of offline by going high ohmic and then resets back to a power supplies, by using high temperature low ohmic value once the overload is removed. Bourns Multifuse PPTC Resettable Fuses. High temperature Bourns Multifuse PPTC Transient overload testing on low-power offline resettable fuses have temperature coefficients converters can be stressful on the output diode which are half the amount of standard and the transformer. The high turns ratio Multifuse PPTCs, giving them more consistent MF-RHT070-0 converts relatively low-peak currents in the hold and trip characteristics. primary side into peak currents of several amps on the secondary side, which can destroy the diode and overheat the transformer. Benefit Solution e BTh ourns Model MF-RHT070-0 resettable 1 Multifuse PPTC Resettable Fuse: fuse reduces the need for larger, more MF-RHT070-0 expensive diodes. It also reduces the need for larger cores in the transformer.
