1 Accu-Guard ACCU-GUARD TECHNOLOGY The Accu-Guard series of fuses is based on thin-film techniques. This technology provides a level of control on the component electrical and physical characteristics that is generally not possible with standard fuse technologies. This has allowed AVX to offer a series of devices which are designed for modern surface mount circuit boards which require protection. FEATURES Accurate current rating Fast acting Small-standard 0402, 0603, 0805, 206 and 062 chip sizes Taped and reeled Completely compatible with all soldering systems used for SMT Lead Free Series (F0402E, F0603E) APPLICATIONS Cellular Telephones Two-Way Radios Computers Battery Chargers Rechargeable Battery Packs Hard Disk Drives PDA s LCD Screens SCSI Interface Digital Cameras Video Cameras APPROVAL FILE NUMBERS UL, cul: RCD#E43842 DIMENSIONS F0603C, F0805B, F206A and F206B B DIMENSIONS F0402E and F0603E B W T T L B 2 L W STANDARD SIZES: millimeters (inches) L W T B F0402E F0603E F0603C F0805B F206A/B F0603D.00±0..60±0..65± ±0.2 3.±0.2.65±0.25 (0.039±0.004) (0.063±0.004) (0.065±0.0) (0.083±0.008) (0.22±0.008) (0.065±0.0) 0.55± ± ±0.5.27±0..6±0. 3.±0.2 (0.022±0.003) (0.032±0.004) (0.03±0.006) (0.050±0.004) (0.063±0.004) (0.22±0.008) 0.40± ± ± ±0.2.2± ±0.2 (0.06±0.004) (0.025±0.004) (0.035±0.008) (0.035±0.008) (0.047±0.008) (0.036±0.008) 0.20± ± ± ± ± ±0.5 (0.008±0.004) (0.04±0.006) (0.04±0.006) (0.02±0.006) (0.07±0.0) (0.04±0.006) HOW TO ORDER F 206 A 0R20 F W TR Product Fuse Size See table for standard sizes Fuse Version A=Accu-Guard B=Accu-Guard II C=Accu-Guard II 0603 D=Accu-Guard II 062 E=Accu-Guard II 0402, 0603 Rated Current Current expressed in Amps.
