Abstract : The procedure is set forth of calculation of current-distribution circuits with 'micron' -type tape cores which have a relatively narrow square loop and, hence, a low power consumption; they operate within minus 60 plus 50C at clock frequencies up to 500 kHz. Four conditions of operability of a transmiting microcell should be observed: (1) for a reliable priming of load cores C, the conducting branch should satisfy a given condition; (2) the volt-sec capacity of a given winding of the nonconducting core should not be lower than the total v-s capacity of the conducting branch carrying the collector current; (3) the voltage pulse developed by the shaper should produce sufficient collector current; (4) an overvoltage protection should be given to the transistor in the shaper circuit. Function calculation procedure along the above four points is given. Test results of two hookups of micro current-distribution circuits are briefly reported.
