Polymer Tantalum Capacitor Components Exhibit Low ESR Values

11 February 2024

The automotive-grade T51 series vPolyTan polymer tantalum chip capacitors from Vishay are part of Rutronik’s comprehensive passive components range.

They are supplied in compact package sizes D (EIA 7343-31) and V (EIA 7343-20). Capacitance values from 2.2µF through to 330µF are offered, with ±20% capacitance tolerances being maintained. The high ripple current capabilities that they exhibit (up to 2.37A) make these components very effective in the decoupling, smoothing and filtering of vehicles’ switching power supplies and point-of-load (POL) converters. They have equivalent series resistance (ESR) figures that go down to just 40mOhm. Their operating temperature range spans from -55°C to +125°C.
