MLCCs are qualified to AEC-Q200 & rated for 1,000VDC

A series of high voltage, automotive grade, MLC, radial-leaded capacitors has been introduced by AVX. The SV series capacitors are designed with C0G (NP0) Class I dielectric materials, which exhibit an extremely low dissipation factor, providing excellent high rms current handling capabilities with minimal power losses in medium to high power resonant converters. 

Qualified to AEC-Q200 and rated for 1,000VDC, the devices also feature radial leads, which enable the mechanical decoupling of the MLC chip from the board and provide the maximum mechanical stress relief necessary for harsh automotive applications. Conformally coated to eliminate the potential for arc flashover, the capacitors also exhibit excellent high frequency performance and capacitance retention with frequency.

Standard automotive applications that the SV capacitors are suitable for include underhood sensors, water pumps, motor controls and temperature regulation systems. Hybrid automotive applications that the devices are particularly well suited for include battery controls, inverter/converter circuits and both wired and wireless charging stations, such as combined magnetic resonant induction chargers, DC/DC converters and hybrid control and clutch control units. In addition to automotive applications, the devices are also suitable for use in high frequency power converters, resonators, snubbers, and general and SMPS power supplies, and can be used for AC line filtering, high voltage AC coupling, and high voltage DC blocking.

The capacitors are available in three case sizes, three tolerances, and with capacitance values spanning 1,000pF to 0.015µF. Rated for use in temperatures ranging from -55 to +125°C, the SV devices are also available with both tin/lead and RoHS-compliant leads. All three case sizes are 5.08mm thick, but their length and height varies; SV05/SV55 cases measure 11.9x10.2mm, SV13/SV63 cases measure 7.62x9.14mm and SV14/SV64 cases measure 10.2x11.7mm. Packaged on tape and reel in 1,000-piece quantities, the capacitors feature standard lead times, and pricing is available upon request.

“The demand for low loss capacitors like those within the SV series is increasing in response to the emergence of strongly coupled magnetic resonance technology that enables the wireless transmission of power to recharge batteries,” said Nic Billig, Product Manager, AVX. “Although multiple parts may be required in parallel depending on the power transmission levels of the application at hand, the SV capacitors reliably handle high rms currents with minimal power losses in a wide range of harsh automotive and power applications.”
