ic protector overcurrent protection elements rev.f 1/5 circuit protection elements z circuit protection elements rohm?s circuit protectors have a very reliable current cut-off capability that protects ics and their circuits from accidental short circuit loads. whether operated in ac or dc circuits, these circuit protectors have a very low internal resistance in normal operation, but safely and rapidly break the circuit when the current cutoff level is exceeded. z features 1) sharp and stable cutoff characteristics. 2) low internal resistance and minimal voltage drop. 3) incombustible. 4) compact. 5) rated for continuous use. 6) good temperature characteristics. 7) withstands surges well. 8) ul certified (ul certification number e107856). z application current surge protection z operation notes do not use this product on the primary side of commercial power supplies. arcs that result after cutoff may damage the molding. use caution when electric current exceeds the rated level. ensure that the voltage between terminals is below 50v during interruptions / cutoffs. surface mounting type z icp-s series icp-s0.5 icp-s0.7 icp-s1.0 icp-s1.2 0.5 0.7 1.0 1.2 0.150 0.084 0.061 50 ? 55 to + 125 ? 55 to + 125 0.048 fig.1 fig.2 fig.3 fig.4 product name rated current (a) internal resistance typ.( ? ) cutoff characteristics rated voltage (v) operating temperature ( c) storage temperature ( c)
