Halogen-free leaded MLCCs for automotive and general-purpose applications

• Halogen-free to support the design of environmentally friendly applications
• Wide rated voltage range (6.3 V to 630 V) and capacitance range (1 pF to 100 μF)
• Designed for harsh environmental conditions with temperature of up to +150 °C
• Automotive-grade series qualified to AEC-Q200

TDK Corporation presents two new series of leaded MLCCs, which are halogen-free according to IEC 61249-2-21* and expand the company’s lineup of products that offer minimal impact to the environment over the entire life cycle. The new components will be available in two specifications: the commercial-grade FG series and the automotive-grade FA series. Unlike conventional products, the new series do not use halogen as a flame retardant in the external resin coating, thus supporting the design of environmentally friendly applications. Mass production will be launched in April 2015.

The commercial-grade FG series covers a wide rated voltage range of 6.3 V to 630 V, and a capacitance range of 1 pF to 100 μF, while the automotive-grade FA series is available with rated voltages from 25 V to 630 V and rated capacitance values from 100 pF to 22 μF. The lineup of the FA series features MLCCs with NP0 and X8R temperature characteristics, which are designed for high temperature environments of up to +150 °C. In addition, this series is qualified to AEC-Q200.

The use of leaded MLCCs in automotive electronics is growing. Modern cars can incorporate as many as 100 small electric motors or more in order to satisfy the growing demands for more safety and driving comfort. Leaded MLCCs with welded or crimped connections are widely used in order to suppress EMI caused by these motors. Noise countermeasures for such compact electric motors are bound to become even more important in future, and TDK is continuously expanding its lineup of suitable components.
