Description
The Littelfuse LVR025S is a high-performance PolySwitch PPTC (Polymeric Positive Temperature Coefficient) resettable fuse from the LVR series. Specifically engineered for line-voltage applications, this fuse is rated for 240V AC operation, providing reliable overcurrent protection for transformers, power supplies, and HVAC equipment.
Unlike traditional fuses that must be replaced after a fault, the LVR025S automatically resets once the overcurrent condition is removed and power is cycled, significantly reducing maintenance downtime. With a compact 6.5mm x 11mm rectangular form factor and 5mm lead spacing, it is perfect for space-efficient PCB mounting in diverse industrial and consumer electronic applications.
Key Features
- Resettable Reliability: PPTC technology allows the device to reset after a trip, eliminating the need for manual fuse replacement.
- High Voltage Compatibility: Specifically designed to handle 240V AC, making it ideal for line-voltage circuit protection.
- Precision Current Ratings: Features a 250mA (0.25A) holding current and 560mA (0.56A) trip current for accurate circuit protection.
- Compact PCB-Ready Design: The rectangular, radial-leaded package is optimized for efficient assembly on printed circuit boards.
- Wide Operating Range: Performs consistently in demanding environments with a temperature range of -40°C to +85°C.
Package Includes
- 1 x Littelfuse LVR025S PolySwitch PPTC Resettable Fuse (240VAC)
