Nichicon Corp. has developed the PCM series (chip-type conductive polymer aluminum solid electrolytic capacitors) for automotive applications and industrial equipment requiring a high degree of reliability. At a guaranteed 8,000 hours of operation, the PCM series features the longest life rating in the industry for capacitors rated at 125°C.
The PCM series retains the characteristics of the PCR series (4,000 hours guaranteed at 125°C), such as the same capacitance and ESR, while achieving a longer life (8,000 hours guaranteed at 125°C).
Integration and diversification of control boards is progressing in the automotive industry accompanying technological progress in automotive onboard electronics such as those supporting ADAS and self-driving features. High temperature heat-resistant components are required as a result of changes such as having powertrain ECUs installed in the engine compartment.
In addition, to being heat resistant the capacitors must also be long-lasting. To meet these needs, Nichicon developed the PCM series to be heat-resistant while having long life.
The PCM series further advances the high heat resistance technology of conductive polymer aluminum solid electrolytic capacitors. The PCM series achieves longer life while maintaining characteristics such as capacitance and ESR by further improving the conductive polymer formation methods, optimizing material composition and material design, and increasing the sealing performance.
As a result, this will contribute to further expanding temperature ranges and miniaturization leading to a reduction in production costs and allowing engineers to choose from a broader range of capacitors to meet specific design needs.
