A guide to aluminum capacitor operating temperature ranges

Our new Help Centre article summarises the complete range of aluminum capacitor operating temperature ranges available to the designer today as well as the technologies and mounting styles available within each temperature range.


All capacitors within the above operating temperature ranges are designed for general purpose applications such as filtering, smoothing, decoupling and energy storage.


High temperature aluminum capacitors capacitors (+125°C to +135°C) find applications in general industrial and automotive circuits and ultra-high temperature aluminum capacitors find applications in more extreme industrial and automotive environments, avionics and even down hole applications for +175°C rated devices.
