Murata’s Surface Mount Safety Capacitor Targets Automotive Applications

September 12, 2012 by Jeff Shepard

Murata announced 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 10,000 pF capacitance values.

Murata is a leading manufacturer of electronic components, modules, and devices. The complete range of this Ceramics Technology house includes ceramic capacitors, resistors/thermistors, inductors/chokes, ceramic resonators, buzzers, sensors and EMI suppression filters. Whilst the company gets 40% of its revenue from its ceramic capacitor products, it is also the world leader in Bluetooth & WiFi Modules, and a key manufacturer of power supplies. Murata also designs and manufactures mobile handset antenna families, piezoelectric actuators for fuel injection systems, short focal length ceramic lenses and speaker products.
