The 2920L185DR is a polymeric PTC resettable fuse from Littelfuse's 2920L series. It offers overcurrent protection with a hold current of 1.85 A at 20°C still air and a minimum trip current of 3.7 A. The device is rated for a maximum voltage of 33 V and can handle up to 40 A of fault current. Typical power dissipation in the tripped state is 1.5 W. Initial resistance is 50 mΩ minimum, increasing to 150 mΩ maximum one hour after tripping. At a fault current of 8 A, the fuse trips within 2.5 seconds maximum. The operating temperature range spans -40°C to 85°C. Housed in a 2920 (7351 Metric) concave surface mount package, it is suitable for automated assembly in medium-voltage applications requiring resettable protection.
