METHOD FOR SORTING POSITIVE TEMPERATURE COEFFICIENT (PTC) ELEMENTS |
摘要 |
In a method for sorting PTC elements having different resistance-temperature characteristics, a predetermined voltage that allows a current to sufficiently decay is applied to each of PTC elements A and B, and the PTC elements are sorted on the basis of the difference between the times required for the currents passing through the PTC elements B to reach a predetermined value (e.g., 52 mA).
