Vina Pulse Capacitor
Hybrid Capacitors now offer Higher voltage and lower Self discharge characteristics
VINATech has launched a new family of 3.8 volt cost effective, Hybrid Super Capacitors, with ultra- low Leakage Current.
Features of VPC
- – Low Self Discharge
- – Wide Operating Temperature Range
- – High Operating Voltage
- – High Capacitance
EDLC Technology is continually being developed and enhanced by VINATech’s R&D Team and this has led to the new VPC series which has been developed utilizing standardized EDLC production processes to reduce the cost effect of this advanced technology.
The VPC series, an environmentally friendly Hybrid Lithium Capacitor family, has been developed to reduce costs against more expensive Pulse Battery technologies whilst offering significantly lower ESR with longer life, wider temperature ranges and higher discharge currents from similar sizes and comparable Battery based technology.
