Subject: supportive capacitor mob.com. Перевожу учебник с примерами и рекомендациями по разработке ПО (IOT/M2M COOKBOOK) для создания устройства на базе модулей беспроводной глобальной сети.Трудность вызывает выражение 'supportive capacitor'. Контекст: The supportive capacitor C43 has an associated internal resistor RC43 shown in the equivalent circuit diagram. Added to the circuit were also the resistances RC40, RC41 and RC42.. In the GSM module data sheet, the use of a capacitor with low ESR is required. The value for Low ESR is sometimes is not defined. A capacitor with very low internal resistance is better than two capacitors in parallel with high resistance. In addition, the resistances RT45 and RT46 were added to the circuit. It symbolises the internal resistance of the conductor tracks on the circuit board. If there is a total resistance of 100 mOhm from invisible resistors, then the ripple voltage will rise to 200 mV quickly (100 mΩ x 2 Ampere = 200 mV). How much ripple voltage is allowed is detailed on the GSM module datasheet. Пока у меня только вариант перевода: поддерживающий конденсатор. |

В блок опорного конденсатора С43 входит соответствующий внутренний резистор RC43. Со времен ХХ века цэ - конденсатор, рэ - резистор. РэЦэсороктри - резистор при конденсаторе цэ43. |
