Ge ne ra l Inform a tion:

Phys ic a l Size :

• Bussmann SMT Chip Fuses utilize metal film and ultrasonic

wire bond technologies for superior fusing action and

enhanced reliability.

• The fuse element is bonded to a ceramic substrate and

encapsulated with green-colored glass, providing excellent

short-circuit performance and environmental integrity.

• Substrate and coating thermal expansion coefficients are

closely matched to that of FR-4 epoxy-glass circuit board

for superior joint reliability.

• The end terminations are over-plated with nickel and tin-

lead.

EIA-RS481 (equivalent to IEC 286, Part 3).

• Fuses are orientated in embossed pockets with ceramic

side facing up to facilitate proper mounting (see “Electrical

Characteristics”, General Note 4.)

• Fast acting fuse: Will carry 100% of rated current for a

minimum of 4 hours, and will open within 5 seconds at

250% of rated current (250mA-3A).

General Notes:

1. AC interrupting rating, melting integral and total clearing integral measured at 32V, unity power factor.

2. DC interrupting rating, melting integral and total clearing integral measured at 63V (250mA-3A) and 32V (4-6.5A), with a battery source.

3. Voltage drop measured at 23 ± 3°C ambient temperature with the device mounted on a suitable circuit board trace.

4. It is recommended that fuses be mounted with ceramic (white) side facing up.

5. Device designed to carry rated current for four hours minimum. An operating current of 80% or less of rated current is recommended,

with further derating required at elevated ambient temperatures.

6. Contact Bussmann if higher ampere ratings are needed.
