Vishay’s new vPolyTan Solid Tantalum Chip Capacitors Increase Volumetric Efficiency to Save Space in Handheld Consumer Electronics

Vishay Intertechnology

Vishay Intertechnology commences a new series of vPolyTan solid tantalum surface-mount chip capacitors that delivers increased volumetric efficiency for handheld consumer electronics. Combining polymer tantalum technology with Vishay’s high-efficiency MicroTan→ packaging, the T58 series  is claimed to achieve industry-best capacitance-voltage ratings in six molded case codes, including 47µF-6.3V in the compact M0 (1608-10) case and 220µF-10V and 330µF-6.3V in the BB (3528-20).

  • In these devices, T58 series capacitors are intended for decoupling, smoothing, filtering, and energy storage applications.
  • The devices offer capacitance from 10 µF to 330 µF, with capacitance tolerance of ± 20 %, over voltage ratings from 4 V to 25 V in the MM (1608-09), M0 (1608-10), W9 (2012-09), A0 (3216-18), AA (3216-18), B0 (3528-10), and BB (3528-20) case codes.
  • The capacitors feature low impedance, low ESR from 50 mΩ to 500 mΩ at +25 °C and 100 kHz, and ripple current from 0.224 A to 1.30 A at 100 kHz, and they operate over a temperature range of -55 °C to +105 °C with voltage derating above +85 °C.
  • The rectangular molded case encapsulation of the T58 series is ideal for high-volume PCB assembly, and its special lead (Pb)-free L-shaped facedown terminations offer better contact to the solder pad than traditional facedown-style terminations.
  • RoHS-compliant, halogen-free, and Vishay Green, the devices feature a Moisture Sensitivity Level (MSL) of 3 and are available in tape-and-reel packaging per the EIA-481 standard.

Leveraging patented MAP (multi-array packaging) assembly technology, the capacitors provide a 10 % improvement in space utilization compared with similar devices, saving PCB space and enabling the design of smaller and thinner end products, including smartphones, tablets, and ultra-thin laptops, in addition to wireless cards, network equipment, and audio amplifiers and pre-amplifiers.


Samples and production quantities of the T58 series capacitors are exclusively obtainable, with lead times of six to eight weeks for large orders.
