Littelfuse PolySwitch®, a pioneer of polymeric positive temperature coefficient (PPTC) resettable devices, offers several material platforms to help protect battery applications. The high trip temperature, broad range of hold current ratings, and high voltage ratings available, combined with automotive qualifications are a unique combination for LSP380 and LSP550.
- Qualified to AEC-Q200 for automotive applications
- Compact size (chip length and width) provides 30%~50% size reduction when comparing to the existing Strap PPTC LR4 devices in the market.
- Hold current ratings 3.8 A and 5.5 A
- Voltage ratings 16 Vdc
- Compatible with high-volume electronics assembly
- Low-resistance devices increase battery operating time
- RoHS compliant, halogen-free, and lead-free
