Shock: MIL-STD-202, Method 213, Test Condition I (100 G’s peak for 6 milliseconds). Vibration: MIL-STD-202, Method 201 (10–55 Hz, 0.06 inches total excursion). Salt Spray: MIL-STD-202 Method 101, Test Condition B (48 hours). Insulation Resistance (After Opening): MIL-STD-202, Method 302, Test Condition B. Resistance to Soldering Heat: (Axial Leaded Fuses): MIL-STD-202, Method 210A, Test Condition B (260°C, 3 Seconds). Thermal Shock: MIL-STD-202, Method 107, Test Condition B (–65°C to 125°C). Moisture Resistance: MIL-STD-202, Method 106 (90-98% RH, 65°C). PEAK WITHSTAND CURRENT (lp): These fuses will withstand 50 repetitions of a double exponential impulse wave having peak currents (lp) and peak voltages as listed. The 2AG Indicating Slo-Blo® fuse instantly identifies itself upon opening by showing a discoloration of its glass body. Guesswork and time consuming circuit testing are eliminated. This unique design offers the same quality performance characteristics as the standard 2AG fuse design. PHYSICAL SPECIFICATIONS: Materials: Glass Body, Nickel-Plated Brass Fuse Caps. (Insulating sleeve option available). Soldering parameters: Wave solder — 500°F (260°C), 3 seconds Max. Reflow solder — Not recommended. Solderability: (Axial Leaded Fuses): MIL-STD-202, Method 208. PACKAGING SPECIFICATIONS: Tape and Reel pitch per EIA-296; T1: 52.4mm (2.062") taped spacing; For 1,500 per reel, add packaging suffix, DRT1. For 2,500 per reel, 5mm (.20") add packaging pitch suffix, ERT1. Insulating sleeve option available. NOTE: LF logo, series number, amperage rating, voltage rating, and UL and CSA logos are stamped on the fuse caps. * When ordering the 2AG Indicating Slo-Blo Fuse, an ‘S’ is required after the catalog number.
