RN2 Resistor Embedded Protector REP is a secondary protection element for Li-ion battery protection circuit. Now, most of portables use Li-ion battery. REP works under over-current and over-voltage situation to protect Li-ion battery from explode. As portables become more popular and people care about safety feature, use of Li-ion battery is also going up. Secondary protection element’s application is expanding.
RN2 Resistor Embedded Protector REP applications:
Notebook, tablet PC, smart phone, electric tool, electric power tools, cordless speaker, cordless headset, medical equipment, electric wheel, electric board, electric scooter, energy storage system, smart phone second battery, robot vacuum cleaner, electric cigarette, etc.
RN2 Resistor Embedded Protector REP features:
① Protect Li-ion battery from the overcurrent and the overcharge
② Halogen free
③ Surface mountable fuse
④ Resistor Embedded
⑤ Fast response time
