The new Vinatech Pulse Capacitor (VPC)is a hybrid Supercap, a combination of a Supercap and a Lithium battery. There is also a combination features to recognize: limited leakage current, reasonable energy capacity, long service life and pulses do not shorten the service life. There are also no restrictions on transportation. The temperature specification is standard -20 to +70°C but with derating to 3.5V even -40 +85°C.
For now, the new VPC family is available in a few versions:
- 3.8V 100F - 0.5/2.0A - ø10x30mm
- 3.8V 150F - 1.0/4.0A - ø13x25mm
- 3.8V 250F - 2.5/5.0A - ø13x35mm
Like lithium batteries, there is a deep discharge voltage, so voltage monitoring is required.
For example, charging the VPC can be done with a primary lithium battery so that the VPC can take over the pulses. But it can also be done with an external charging circuit. The ideal application is a longer backup voltage and many charge/discharge cycles.
