NICHICON CORPORATION has launched the PCW Series of conductive polymer aluminum solid electrolytic capacitors with a guaranteed ripple current at high temperatures. This makes the PCW capacitors ideal for use in automotive and telecommunications sectors. The PCW Series is the industry’s first lineup which offers a guaranteed ripple current.
Overview and Development Background
Many automotive circuits are using low voltage PMIC or CPU/GPU control circuits. These circuits have increased the demand for high temperature and high reliability capacitors. To satisfy this demand, the PCW Series is rated for 2,000 hours at a maximum temperature 125° with rated ripple current applied. The PCW Series has optimized the sealing rubber with a high heat-resistant material to improve the reliability.
Features
Aluminum solid electrolytic capacitors that utilize conductive polymers as electrolytes are characterized by both superior ESR in the high-frequency ranges and excellent ripple current durability. Nichicon PCW Series uses highly heat-resistant sealing rubber to maintain stability even at high temperatures while achieving low ESR and reduced self-heating by using a superior lead wire and other optimized materials.
