Surface Mount Fuses Thin-Film Surface Mount SlimLine™ 1206 Very Fast-Acting Fuse 433 Series • For new designs of 7 amp please consult 429 series. • The SlimLine 1206 fuse is an extremely small, low profile design (1206 chip size) utilizing thin-film technology to achieve precise control of electrical characteristics. • The lower height profile produces a flat surface for improved performance in pick-and-place operations and an alternate solution for height critical application. • Mounting pad and electrical specification are identical to the popular 429 Series specifications. ® ® ELECTRICAL CHARACTERISTICS: % of Ampere Rating 100% 200% 300% Opening Time at 25°C 4 hours, Minimum 5 seconds, Maximum 0.2 seconds, Maximum Reference Dimensions: MARKING CODE VARIES WITH AMPERAGE RATING (SEE CHART) Sn/Pb AGENCY APPROVALS: Recognized under the Components Program of Underwriters Laboratories and Certified by CSA. .66 (.026") .58 (.023") .56 (.022") Coating AGENCY FILE NUMBERS: UL E10480, CSA LR 29862.
