Pulse Capacitors

2 High specific energy density, strong capacitors energy storage
2 Low ESR, high ripple current and Large peak current shock handling capabilities
2 Low Inductance, Dv/dt large, frequency characteristics is good.
2 Self-healing property
2 Long lifetime(≥100000h)
2 High vacuum note oil, heat dissipation of capacitor performance is stable and reliable
2 Huge capacitance
2 High thermal conductivity
