Допустимые значения ESR конденсаторов. Печать

hitanocapsЭквивалентное последовательное сопротивление (далее ЭПС (анг. ESR)) - один из параметров конденсатора, характеризующий его активные потери в цепи переменного тока. Определяется в электрическом сопротивлении материала обкладок конденсатора и выводов, контакта между ними, плюс потери в диэлектрике. Не смотря на достаточно четкое определение результаты замеров параметра разными ESR-измерителями могут отличаться, ввиду того что разные измерители проводят замеры на разных частотах. И часто попадаются приборы, которые имеют собственную таблицу допустимых значений ESR исходя из специфики своих измерений.

Большинство радиолюбителей (при отсутствии таблицы допустимых значений на приборе) использует таблицу Боба Паркера, т.к. большинство приборов используют аналогичный способ измерения ESR.

Возможно, эта таблица (значения в таблице в ,Ом) будет полезна вам при оценке качества конденсаторов для последующего их использования.

Но в любом случае, чем меньше ESR, тем лучше!

Hello just wanted to give you a quick heads up. The text in your article seem to be running off the
screen in Opera. I'm not sure if this is a format issue or something to do with
web browser compatibility but I figured I'd post to let
you know. The design and style look great though!
Hope you get the problem solved soon. Cheers
