Their ultra-small size (0402 size) makes them ideal for secondary protection of circuits used in space constrained applications such as hand-held portable electronic devices. This series is 100% lead-free and meet the requirements of the RoHS directive. New Halogen-Free 435 Series fuses are available–to order use the “HF” suffix. See Part Numbering section for additional information. ## ~~**Features**~~ ## ~~**Agency Approvals** Lo~~ AgeNCy AgeNCy FIle NumbeR AmpeRe RANge \ e10480 0.250 - 5.0A lR 29862 0.250 - 5.0A |~~**Electrical Characteristics for Series**~~
