| Axial and Radial Lead Fuses Subminiature PICO(R) Fuse Very Fast-Acting Fuse 275L/276L Series ELECTRICAL CHARACTERISTICS: % of Ampere Rating 100% Ampere Rating 1/16-30 1/16-10 200% 12-30 Opening Time 4 hours, Minimum 5 second, Maximum 10 seconds, Maximum (R) (R) AGENCY APPROVALS: Recognized under the Components Program of Underwriters Laboratories and Certified by CSA. AGENCY FILE NUMBERS: UL E10480, CSA LR 29862. INTERRUPTING RATINGS: 300 amperes at rated VDC 50 amperes at rated VAC ENVIRONMENTALSPECIFICATIONS: Operating Temperature: -55C to 125C. Shock: MIL-STD-202, Method 213, Test Condition I (100 G's peak for 6 milliseconds) and per method 2028 (78 G`s peak for 11 millseconds). Vibration: MIL-STD-202, Method 204A; Test Condition D (vibrations of 10-2000 cps at 20 G`s). Insulation Resistance (After Opening): MIL-STD-202, Method 302, Test Condition A (1/2 Megohm minimum). Moisture Resistance: MIL-STD-202, Method 106. PHYSICALSPECIFICATIONS: Materials: Pure tin coated copper wire leads. Solderability: MIL-STD-202, Method 208. Lead Pull Force: MIL-STD-202, Method 211, Test Condition A (will withstand a 5 lb. axial pull test). VARIATIONS IN DESIGN: Picofuses which differ from the standard versions as presented on this page can be provided for a commercial or military use. One such design version is where the picofuse terminates at one end of a pin for use as a single or multi-pin connector. Extreme accuracy in blowing time at 300% or more of rating, makes these picofuses suitable for use in circuits where sequential switching or redundancy may be required. The small size of the fuse, its non-hygroscopic characteristic and infinitesimal weight makes it the ideal fuse for micro-electronic circuits.
