0154.630DR Description

Short technical summary and product information.

The Littelfuse 154 Series OMNI-BLOK fuse and holder assembly offers a compact, surface mount solution for overcurrent protection in space-constrained designs. This 0154.630DR variant provides a 630mA current rating with fast blow response, suitable for protecting sensitive circuits from short circuits and overloads.

 

The fuse is rated for 125VAC/VDC and features a high interrupting capacity of 50A at rated voltage, ensuring reliable fault clearing. The melting I²t of 0.143 provides coordination guidance for engineers designing protection schemes. The assembly operates across a wide temperature range of -55°C to 125°C.

 

The package is a 2-SMD square end block with holder, sized at 9.73mm x 5.03mm x 3.81mm. The holder allows easy fuse replacement without resoldering, reducing maintenance costs and board stress. The part is RoHS compliant and halogen-free, supporting green manufacturing initiatives.
