Battery Protectors
NEC SCHOTT works closely with our customers to develop innovative new products. Two examples of this are the SEFUSE® D6 Type and SEREB® SB Type. These premium quality battery protection and thermal cutoff components serve as a crucial means of protection for lithium ion (Li-ion) battery packs. NEC SCHOTT will work directly with you to determine the best way to fulfill your application needs. We can advise on the implementation of the SEFUSE® D6 type or SEREB® SB type to secure reliable protection for Li-ion battery packs. For maximum protection, we can meet your requirements by integrating both the SEFUSE® D6 and SEREB® SB type in the same application. Our experienced research and development team works closely with our customers to create innovative solutions for the electronics market. One of our latest achievements is the NEC SCHOTT SEFUSE® D6 type. This is the second protection device in the D6 series for electrical equipment. The D6 series (D6T / D6X / D6WX) The D6 series is a line of dual safety devices which integrate a thermal link and resistor as a heater and use a ceramic material for the device (cap and base). The D6 series is activated when an abnormal temperature increase is caused by the external environment or heat generated by the electrical circuit within the device. This provides a second layer of protection for electrical equipment the D6 series is installed in. The D6S series D6SA and D6SC devices are ultra-thin surface mount devices ideal for limited-space Lithium-ion battery applications. The self-heater activates when overcharging occurs, which will activates the fuse and cuts off the circuit. SEREB® is a thermal protector integrated into the battery cells of various portable electronic devices. It interrupts the current flow in the event of overheating or when over-current causes self-generation of abnormal heat levels. In these situations, the rise in temperature will cause the bimetal element within the protector to reverse, shunting the conductive line to the PTC ceramic. The bimetal element remains reversed until there is a sufficient voltage drop.
