High temperature capacitor series from Panasonic maintains specified ESR at low temperatures

Panasonic has introduced the TP-Series, the newest high temperature SMD capacitor in a range of aluminium electrolytic capacitors, which uses the latest material technologies to maintain ESR down to -40°C.

The TP-Series is rated 125°C with a lifetime of up to 3000 hours. Compared to the previous series (e.g. TG or TK) it uses the latest materials to improve Equivalent Series Resistance (ESR) under adverse conditions, with the ESR now being specified after endurance at -40°C, a worst case scenario. This allows the Development Engineer a calculation of his circuit and whether the application is still fulfilling the requirements at the end of life.

As an example, the value of 220uF, 35V in case size G (10mm x 10.2mm) has an initial ESR value of 0.15 Ohm at +20°C/100kHz and after the lifetime of 2000 hours at -40°C specifies a value of 3.5 Ohm max.

The TP-Series offers voltage ratings from 10V to 35V and capacitance values from 47uF to 470uF. It is suitable for high temperature, lead-free reflow soldering.

With its high temperature performance and specified lifetime, this series is ideally suited for automotive electronics or rugged industrial applications such as power supplies.
