<p>A positive-characteristics thermistor apparatus has an insulating case (1), positive-characteristics thermistor devices (5, 6), planar terminals (10, 11), and spring terminals (12, 13). Whichever thermistor device has a lower resistance of the two thermistor devices (5, 6) is trimmed to have a higher resistance which is near the resistance of the other thermistor device such that the two thermistor devices have substantially the same resistance (for example, within a difference of +/-1 OMEGA ). In other words, a part of an electrode of the thermistor device having a lower resistance is removed with a laser beam. <IMAGE></p> |
