Electrical Speciﬁcations by Item

1. Measured at 10% of rated current, 25ºC.

2. Measured at rated voltage.

The 435 Series are fast-acting surface mount thin-ﬁlm

fuses. 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.
