摘要： A thermistor with positive resistance-to-temperature characteristic used in a overcurrent protection circuit has electrodes on mutually opposite main surfaces and is mounted to a substrate having electrically conductive members such that deterioration of its voltage resistance due to heat emission can be controlled. A spacer with smaller thermal conductivity than the substrate and penetrated by a conductor piece with a small cross-sectional area is inserted between solder materials connecting to one of the thermistor electrodes. The other electrode is contacted by an elongated connecting member through its sectional surface transverse to its longitudinal direction such that the cross-sectional area of electrical conduction is reduced.

摘要： A small-size high-performance electronic protective device (10) is provided for use in protecting communication equipment including an exchange servicing module against application of abnormal surge current due to accidental shorts between adjacent ones of power feed lines in a communications system. The protective device (10) includes positive thermistors (3a, 3b) connected between communication link input terminals (1a, 1b) and output terminals (1c, 1d) coupled to an associative equipment being protected. The protective device (10) also includes thick-film resistive elements (5a, 5b), which are connected in parallel with the thermistors (3a, 3b), respectively.

摘要： A protection device for a communication system is inserted between a circuit side and a subscriber side and includes a protection circuit part and trimmable resistors. The protection circuit part includes a tip line and a ring line each extending between an input terminal and an output terminal. The tip line and the ring line each contain at least one thermistor with positive temperature characteristic or one protection resistor as overcurrent-protecting element. The output terminals of the tip line and the ring lines are connected, say, by a diode bridge of which one terminal is grounded and another terminal connected to a power source. Trimmable resistors are each connected to a corresponding one of the output terminals of the protection circuit part and are adapted to be trimmed such that impedance imbalance between the tip and ring lines can be reduced.
