Abstract:
Disclosed is a reflow solderable positive temperature coefficient circuit protective device, comprising: an upper conductive blade terminal ( 1 ), which is composed of a first chip bonding portion ( 101 ), a first circuit bonding portion ( 105 ) and a connecting portion ( 103 ) therebetween, wherein the first chip bonding portion ( 101 ) has a first planar profile; a lower conductive blade terminal ( 2 ), which comprises a second chip bonding portion ( 201 ) having a second planar profile; a positive temperature coefficient chip, which is sandwiched between the upper conductive blade terminal ( 1 ) and the lower conductive blade terminal ( 2 ) and respectively bonded to the lower surface of the first chip bonding portion ( 101 ) and the upper surface of the second chip bonding portion ( 201 ) via solder, and has a third planar profile, wherein: the first planar profile and the second planar profile are in the interior of the third planar profile, and the third planar profile has portions that are not covered by the first planar profile and/or the second planar profile, so as to allow the positive temperature coefficient chip to have a free thermal expansion space. By using the device, the stress caused by high temperature thermal expansion in the device, which can lead to device failure, can be reduced in a protection state.

Claim (Index 4):
The PTC circuit protection device according to  claim 1 , wherein\n an anti-overflow gap is provided between edges of the first planar profile and the third planar profile, and/or an anti-overflow gap is provided between edges of the second planar profile and the third planar profile.
