0603 Chip Size Surface Mount PTC Resettable Fuse 0.1A 0.2A 0.35A 0.5A Hold Current
Description Of The 0603 Chip Size Surface Mount PTC Resettable Fuse
◆ Available in 4 hold current ranges 0.10A, 0.20A ,0.35Aand 0.5A, each device is certified by both TUV and UL and possess a maximum fault current rating of 40A.
◆ Similar to traditional fuses though automatically resettable, PPTCs provide overcurrent protection of sensitive electronics. PPTCs increase resistance as temperature increases due to increased current flow. They limit unsafe currents while allowing constant safe current levels, and reset when the current and temperature returns to a safe level.
◆PPTCs are typically used in sensitive electronic applications where frequent over-current conditions can occur, constant system uptime is required, and automatic resetting desired. With its ultra-small size and resettability, the 0603L series is ideal where miniaturization is desired, space is limited, and limited accessibility (due to size or location) is a factor.
