446/447 Series EBF Fuse Fast-Acting

Description

The 446/447 series are circuit-board mountable, ﬂat proﬁle,

fast-acting fuses designed for protection of electronic

ballasts and power inverter applications. The 446 series is

designed with leads for surface mount applications, and

the 447 series is designed with leads for through-hole

applications.

446 Series

(surface mount leads)
