DescriptionThe 0452003.MR is one member of the 452 series which is designed as surface mount fuses. It 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. Typical applications include notebook pc, LCD/PDP TV, LCD monitor, LCD/PDP panel, LCD backlight inverter, portable DVD player, power supply, networking, PC server, cooling fan system, storage system, telecom system, wireless basestation, white goods, game console, office automation equipment, battery charging circuit protection, industrial equipment, medical equipment and automative. Its quantity would be 1000 pcs and its package would be tape and reel.
The 0452003.MR series have seven features. (1) Time-lag (slo-blo). (2) It would have small size. (3) It would be available for wide range of current rating (375mA to 5A). (4) It would have wide operating temperature range. (5) It would have low temperature de-rating. (6) It would be RoHS compliant. (7) It would be halogen free. That are all the main features.
Some electrical characteristics about 0452003.MR (1) Its ampere rating would be 3.00A. (2) Its max voltage rating would be 125V. (3) Its interrupting rating would be 50A at 125 VAC/VDC and it would be 300A at 32VDC. (4) Its nominal cold resistance would be 0.0340 ohms. (5) Its nominal melting I2t would be 20.16 A2sec.
Also some some soldering parameters about 0452003.MR (1) Its reflow condition would be Pb-free assembly. (2) Its pre heat would be min 150°C and max 200°C and time from min to max is 60 to 120secs. (3) Its average ramp up rate to peak would be 5°C / second max. (4) Its Ts(max) to Tl ramp-up rate would be 5°C/second max. (5) Its peak temperature would be 250°C. (6) Its time within 5°C of actual peak temperature would be from 20 to 40 seconds. (7) Its ramp-down rate would be 5°C/ second max. (8) Its time 25°C to peak temperature would be 8 minutes max.
