The Littelfuse LVR055K is a polymeric PTC (Positive Temperature Coefficient) resettable fuse, part of the PolySwitch® LVR series. It is designed to provide reliable overcurrent protection in various electronic applications.
This fuse features a maximum operating voltage of 240V (with an internal rating of 265V) and a maximum hold current (Ih) of 550mA. When tripped, it can handle a maximum current of 7A, and it trips within 26 seconds at 1.25A. The initial resistance is a minimum of 450mOhms, increasing to a maximum of 1.45 Ohms after tripping.
Designed for through-hole mounting, the LVR055K comes in a radial disc package. Its operating temperature range is from -20°C to 85°C, making it suitable for a wide array of environmental conditions. The dimensions are 0.551" L x 0.161" W (14.00mm x 4.10mm), with a maximum seated height of 0.822".
This resettable fuse offers a convenient alternative to traditional fuses, as it can be reset after a fault condition is cleared. Its active status indicates it is a current production part.
