Ultra thin chip thermistor, comprising a substrate, electrode, pins, slurry layer, outer electrode, pin and insulating coating, the inner electrode by base leads, inner pins by inner electrode leads, outer electrode leads by slurry layer, draw out pin by external electrode, insulating coating covered on the outer electrode layer on both sides of a substrate the groove, slurry layer is filled in the groove, both sides of the base groove are mutually staggered, as small and medial lateral groove mouth big mouth shape, the substrate is thin ceramic substrate; slurry filling in base groove and drying, so repeatedly after high temperature sintering to form a layer of slurry layer, slurry layer has at least two layers. The utility model has the advantages of ultra-thin chip thermistor can effectively prevent the grooves in the slurry layer and the outer layer of the electrode paste leads off, but also can reduce the thermal resistance of the thickness of the plate, and the maximum to prevent substrate thinning the substrate firmly without fracture. The utility model relates to an ultra-thin chip thermistor, which can be widely used in electrical appliances, electronic and electric equipment.
