Murata – Surface-mount safety capacitor targets automotive applicationsSep 14 2012 - Passives [More Passives Articles]
Murata has introduced what is believed to be the world’s first SMD safety ‘Y2′ capacitor designed for automotive applications. Approval to the internationally recognized standard for safety capacitors, IEC 60384-14 that stipulates protection from electrical shock and risk of fire is pending. With the growing demand for electric (EV) and hybrid electric vehicles (HEV), the KCA series of capacitors are ideal as part of an AC power line filter in a battery charger or as a DC line filter of a DC-DC converter / inverter unit.
The construction of the KCA series also incorporates techniques to improve long-term resilience against vibration and bending stresses. This includes the use of metal terminals as protection against substrate expansion and contraction forces that can cause solder crack failure as a result of the wide temperature changes experienced. Also, the series offer higher reliability characteristics compared to discrete capacitor elements since they are designed to accommodate the higher levels of mechanical shock and movement encountered in any automotive environment.
The KCA series is also certified to the automotive industry AEC-Q200 stress test qualification for passive components. Rated at 630 VDC working voltage, the KCA series is available in 2,200, 4,700 or 10,000pF capacitance values, says the company.More news from Murata
