Technical content
devices(PTC),provide over-current protection for electrical and electronic devices. They function using conducting strips of metal imbedded inside polymers. Under normal conditions, the devices resistance is near zero, but over-current conditions will heat the PTC and expand the polymer, increasing the impedance. When current returns to normal, the components cool down, returning to their original shape and very low levels of resistance. l Over-current and over-temperature protection of automotive electronics l Hard disk drives l PC motherboards l Point-of-sale (POS) equipment l PCMCIA cards l USB port protection - USB 2.0, 3.0 & OTG l HDMI 1.4 Source protection l Computers & peripherals l Industrial control l I(hold): 0.05~2.0A l 240V Operating voltages l Radial leaded devices. l Over-current protection l Very high voltage surge capabilities. l Available in lead-free version. l Fast time–to–trip l RoHS compliant, Lead- Free and Halogen-Free Environmental Specifications Test Conditions Resistance change Passive aging +85℃，1000hrs ±8% typical Humidity aging +85℃，85%R.H.1000hrs ±8% typical Thermal shock +125℃ to -55℃，10times ±12% typical Resistance to solvent MIL-STD-202，Method 215 No change Vibration MIL-STD-202，Method 201 No change SMVR240 Series POSITIVE THERMAL COEFFICIENT(PTC)
