Description & ApplicationsSurface Mount Fuses Subminiature Surface Mount NANO2® Slo-Blo® Fuse 452/454 Series The NANO2 Slo-Blo fuse has enhanced inrush withstand characteristics over the NANO2 Fast-Acting fuse. The unique time delay feature of this fuse design helps solve the problem of nuisance “opening” by accommodating inrush currents that normally cause a fast-acting fuse to open. Vibration: MIL-STD-202, Method 201 (10–55 Hz, .06 in. total excursion). Salt Spray: MIL-STD-202, Method 101, Test Condition B (48 hrs.). Insulation Resistance (After Opening): MIL-STD-202, Method 302, Test Condition A, (10,000 ohms minimum). Resistance to Soldering Heat: MIL-STD-202, Method 210, (3 sec. at 260°C). Thermal Shock: MIL-STD-202, Method 107, Test Condition B (–65 to 125°C). Moisture Resistance: MIL-STD-202, Method 106, High Humidity (90-98 RH), Heat (65°C). PHYSICAL SPECIFICATIONS: Materials: Body: Ceramic Terminations: Tin-Lead Alloy or Silver Plated Brass Caps. Soldering Parameters: Wave Solder — 260°C, 3 seconds maximum Reflow Solder — 230°C, 30 seconds maximum Solderability: MIL-STD-202, Method 208.
