Позисторы и полисвичи » MZ23-25R (R25)
MZ23-25R (R25)Предлагаемые Вам позисторы являются полным аналогом позистора B59870-C80-A70 производства Epcos, а также улучшенным аналогом отечественных ТРП27-27, ТРП25-27, ПТ60-3. Новый позистор имеет меньший габаритный размер и более высокое быстродействие, чем все прежние позисторы. Кроме того, нам удалось сохранить для него очень низкую цену 4,5руб-4,00руб за 1 штуку .
Параметры позисторов указаны в таблице.
