Semiconductor Fuses with Higher Amperage Ratings in Smaller Case Sizes
The Littelfuse award-winning Powr-Speed PSR series of high-speed semiconductor square-body fuses keeps growing. There are new amperage ratings for customers who need higher current in smaller case sizes. They offer a more economical solution to protect sensitive semiconductor devices from overcurrent surges and extend the life of critical power equipment.
PSR high-speed square-body fuse features include:
- Extremely current limiting properties to protect components and devices
- Higher amperage rating in a smaller case size for added design and cost flexibility
- Silicone sealant to prevent leakage for increased reliability
- Low watt loss to reduce energy wasted during operation
- Optimized performance for balanced speed of operation, energy efficiency and longevity
- A broader range of amperage ratings in eight case sizes to accommodate more applications
- Flush-end, bolted-blade and DIN-blade styles for mounting versatility
- Environment-friendly RoHS and REACH compliance to offer greater acceptance globally
- Power conversion devices (UPS, inverter, rectifiers, drives)
- Dc systems (dc common bus, dc injection braking)
- Battery protection applications (energy storage systems)
- Electric vehicle charging stations
- Heaters and power supplies
