Rutronik extends its capacitor portfolio with the vPolyTan Polymer-Tantalum Chip Capacitors of the T51 series, which are ideal for applications in the automotive industry.

The AEC-Q200 qualified components impress with their extremely low ESR, lower voltage derating, and safe failure mode, combined with higher volumetric efficiency than comparable conventional tantalum capacitors.

Due to their high ripple current capability of up to 2.37A, the capacitors are particularly suitable for decoupling, smoothing, and filtering in switching power supplies and point-of-load (POL) power supplies for ADAS, infotainment, and other electronic systems in automobiles and other vehicles.

Available in compact package sizes D (EIA 7343-31) and V (EIA 7343-20), the components offer a wide capacitance range from 2.2µF to 330µF at nominal voltages from 2.5V to 35V and a capacitance tolerance of ± 20%. Equipped with a highly conductive polymer cathode system, they are characterised by extremely low equivalent series resistances (ESR) in the range from 40 mΩ to a maximum of 120 mΩ at +25°C.

The robust design enables reliable performance at temperatures up to +125°C (voltage derating above +105°C) and continuous load operation of up to 2,000 hours at a maximum of +125°C.

Features at a glance:

  • Capacitance range: 2.2µF to 330µF
  • Capacitance tolerance ± 20%
  • Voltage range: 2.5 VDC to 35 VDC
  • AEC-Q200 qualified / automotive grade

  • High temperature and humidity resistance (85°C / 85% RM at rated voltage)
  • 100 % surge current tested

Examples of applications in the automotive industry:

  • Switching mode
  • Point-of-Load (POL) power supplies for ADAS, infotainment, and other electronic systems
