Withstanding surge current times of the calibrated value because of the peak voltage in alternating In general, withstanding surge current is max. Pulse current value which determined by test conditions such as wave-shape, shock times and interval time etc, the change ratio of Varistor Voltage should be less than ±10% of the initial Value. The shock time is the function of wave - shape, amplitude and interval time ,when the amplitude decrease to 50% of the initial, it should be increased to 2 times of the initial in order to keep the life longer, the surge current which is absorbed by the varistor should be less than max. Withstanding surge current. GENERAL TYPE DIMENSIONS General type is widely used in surge protection for IC. diode. trial semiconductor, thyristor, consumer, military industry telecommunication measuring & controlling instrument etc. H (V) Varistor Voltage D Max D ±0.1 W ±1.0 Max 18~ 82 100~ 470 18~ 470 18~ 330 360~ 1100 18~ 330 14 360~ 1100 180 18~ 330 360~ 1100 20 1800 25.0 1.0 15.0 30.0 12.0 7.0 7.5 9.0 13.5 14.0 17.0 17.5 25.0 23.0 24.0 0.6 0.6 0.6 0.8 0.8 0.8 0.8 0.8 1.0 1.0 5.0 5.0 5.0 7.5 7.5 7.5 7.5 15.0 10.0 10.0 10.0 10.0 12.0 16.5 17.0 20.0 20.5 30.0 27.0 28.0 3.5 6.0 6.0 5.4 8.5 5.4 8.5 12.0 5.5 9.0 T Max D T H 05 07 10 3 min Фd w LIGHTNING ARRESTER TYPE Lightning arrester type is ideal for semiconductor, signal relay, telecommunication, calibrating equipment, communication inter-medium station, distribution board, surge absorption and lightning-protection of all sorts of electric equipment because of the properties, with the Great withstanding surge current, wide voltage, quick responding speed and low residual voltage etc. D Dimensions(mm) Part No. D T W d H T FNR-25 30 12 15 1.5 30±1mm Фd FNR-32 38 13 18 1.5 FNR-40 45 13 20 1.5 w www.fenghua.com 2/8 ZINC OXIDE VARISTOR GENERAL TYPE PRODUCTS SERIES Varistor Voltage V(v) FNR-05K180 FNR-07K180 FNR-10K180 FNR-14K180 FNR-20K180 FNR-05K220 FNR-07K220 FNR-10K220 FNR-14K220 FNR-20K220 FNR-05K270 FNR-07K270 FNR-10K270 FNR-14K270 FNR-20K270 FNR-05K330 FNR-07K330 FNR-10K330 FNR-14K330 FNR-20K330 FNR-05K390 FNR-07K390 FNR-10K390 FNR-14K390 FNR-20K390 FNR-05K470 FNR-07K470 FNR-10K470 FNR-14K470 FNR-20K470 FNR-05K560 FNR-07K560 FNR-10K560 FNR-14K560 FNR-20K560 FNR-05K680 FNR-07K680 FNR-10K680 FNR-14K680 FNR-20K680 FNR-05K820 FNR-07K820 FNR-10K820 FNR-14K820 FNR-20K820 FNR-05K101 FNR-07K101 FNR-10K101 FNR-14K101 FNR-20K101 18 18 18 18 18 22 22 22 22 22 27 27 27 27 27 33 33 33 33 33 39 39 39 39 39 47 47 47 47 47 56 56 56 56 56 68 68 68 68 68 82 82 82 82 82 100 100 100 100 100 Maximum Operating Voltage AC DC(v) (v) 11 11 11 11 11 14 14 14 14 14 17 17 17 17 17 20 20 20 20 20 25 25 25 25 25 30 30 30 30 30 35 35 35 35 35 40 40 40 40 40 50 50 50 50 50 60 60 60 60 60 14 14 14 14 14 18 18 18 18 18 22 22 22 22 22 26 26 26 26 26 31 31 31 31 31 38 38 38 38 38 45 45 45 45 45 56 56 56 56 56 65 65 65 65 65 85 85 85 85 85 Maximum Clamping Voltage VC(v) 40 36 36 36 36 48 43 43 43 43 60 53 53 53 53 73 65 65 65 65 86 77 77 77 77 104 93 93 93 93 123 110 110 110 110 150 135 135 135 135 145 135 135 135 135 175 165 165 165 165 IP(A) 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 1 2.5 5 10 20 Maximum Withstanding Surge Current(8x20us) 2Time(A) 50 125 250 500 1000 50 125 250 500 1000 50 125 250 500 1000 50 125 250 5.
