AVX Corp. has introduced the SV Series high-voltage, automotive-grade, multilayer ceramic (MLC), radial-leaded capacitors. Qualified to AEC-Q200 and rated for 1,000VDC, the new SV Series capacitors are designed with C0G (NP0) Class I dielectric materials. These materials exhibit an extremely low dissipation factor providing high rms current handling capabilities with minimal power losses in medium to high power resonant converters and radial leads. These specifications enable the mechanical decoupling of the MLC chip from the board, and provide the maximum mechanical stress relief necessary for harsh automotive applications. With a uniform coating to eliminate the potential for arc flashover, SV Series capacitors also exhibit high-frequency performance and capacitance retention with frequency.
Standard automotive applications that SV Series capacitors can used for include: underhood sensors (such as oxygen, EATC blower, fuel pump, anti-lock brake, front crash, headlight, and park and turn light sensors), water pumps, motor controls, and temperature regulation systems. The capacitors are also suited for hybrid automotive applications, including: 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 (HCUs and CCUs). In addition to automotive applications, SV Series capacitors are also suited for high frequency power converters, resonators, snubbers, and general and SMPS power supplies; and AC line filtering, high voltage AC coupling, and high voltage DC blocking.
SV Series capacitors are available in three case sizes, three tolerances (J, ±5%; K, ±10%; and M, ±20%), and with capacitance values spanning 1,000pF to 0.015µF. Rated for use in temperatures ranging from -55°C to +125°C, the series is 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 11.9mm x 10.2mm, SV13/SV63 cases measure 7.62mm x 9.14mm, and SV14/SV64 cases measure 10.2mm x 11.7mm. Packaged on tape and reel in 1,000-piece quantities, SV Series capacitors feature standard lead times, and pricing is available upon request.
