The Littelfuse 0459003.ER is a 3A, 125VAC/VDC fast blow surface mount fuse designed for board-level overcurrent protection. It is housed in a compact 2-SMD, J-Lead package measuring 7.24mm x 4.32mm x 3.05mm, making it suitable for space-constrained applications.
This fuse offers a fast response time, providing rapid disconnection during overcurrent events. It is rated for both AC and DC circuits up to 125V, with a breaking capacity of 50A at 125VAC and 300A at 125VDC. The melting I²t is 1.23 A²s, which aids in coordination with downstream components.
The operating temperature range spans -55°C to 125°C, allowing use in harsh environments. It is approved by CSA and UL, and is designed for surface mount assembly with J-Lead terminations.
