When a ripple voltage as from a rectifier source is applied, make sure that the peak voltage is within the Vdcm rating. The AC applied voltage (50/60Hz) is a sine waveform. When waveform distortion is extensive, make sure that the peak voltage is less than 2 times the Vacm rating. 2 * Energy Wtm Transient energy rating are given in the Wtm column in Joules (Wattsecond). The rating is the maximum allowable energy of a single 2ms square-waveform impulse current continuously applied. Energy ratings are based on a shift of Vnom of less than ±10% of the initial value. *3 Transient peak current (Itm) The peak current rating, Itm, is based on 8/20µs test impulse wave form. This peak current is the maximum peak current at which the nominal varistor voltage shift dose not exceed ±10% when the test impulse is applied twice at a 5 minute interval. 4 * Nominal varistor voltage: Vnom Indicates the varistor terminal voltage measured with 1mA DC applied. 05A type 0.1mA DC *5 Maximum clamping voltage: Vc Indicates the peak terminal voltage measured with 8/20µs impulse current applied. 1 Z-TRAP FUJI Ceramic Surge Absorbers ENF series 220 to 680V (Varistor voltage) Characteristic curves (Typical) Transient V-I characteristic curves 2000 (ENF221D05A to ENF471D05A) Max. clamping voltage Max. idle current 1000 900 800 700 600 500 ENF271D05A ENF241D05A ENF221D05A A 71D05 ENF4 400 Voltage [V] ENF471D05A 300 A 71D05 ENF2 A 41D05 ENF2 05A 1D ENF22 200 100 90 80 70 60 50 40 -6 10 -5 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 10 700 Current [A] Transient V-I characteristic curves (ENF221D07A to ENF471D07A) 2000 Max. clamping voltage Max. idle current ENF471D07A 1000 900 800 700 600 500 ENF271D07A ENF241D07A ENF221D07A Voltage [V] 400 1D07A ENF47 300 D07A ENF271 1D07A ENF24 D07A F2 EN 21 200 100 90 80 70 60 50 40 -6 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 1 10 2 10 3 10 10 1350 Current [A] Transient V-I characteristics curve 2000 (ENF221D10A to ENF471D10A) Max. clamping voltage Max idle current ENF471D10A Voltage [V] 1000 900 800 700 600 ENF271D10A ENF241D10A ENF221D10A 500 400 A 71D10 ENF4 300 A 71D10 ENF2 0A 41D1 ENF2 0A 1 21D ENF2 200 100 -6 10 -5 10 -4 10 -3 10 -2 10 -1 10 Current [A] 0 10 1 10 2 10 3 10 2750 2 Z-TRAP FUJI Ceramic Surge Absorbers ENF series 220 to 680V (Varistor voltage) Transient V-I characteristic curves (ENF511D10A to ENF681D10A) 5000 4000 Max. clamping voltage Max. idle current 3000 2000 ENF681D10A Voltage [V] ENF621D10A ENF511D10A 1000 900 800 700 ENF621D10A 600 ENF681D10A 500 400 300 ENF511D10A 200 10 -6 10 -5 10 -4 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 3 2500 Current [A] Transient V-I characteristic curves (ENF221D14A to ENF471D14A) 2000 Max. clamping voltage Max. idle current ENF471D14A 1000 900 800 700 600 500 ENF271D14A ENF241D14A ENF221D14A Voltage [V] 400 14A 471D ENF 300 14A 271D ENF 14A 241D ENF A D14 1 2 2 ENF 200 100 90 80 70 60 50 40 -6 10 -5 -4 10 10 -3 10 -2 10 -1 10 0 10 1 10 2 10 3 10 5500 Current [A] Transient V-I characteristic curves 5000 (ENF511D14A to ENF681D14A) 4000 Max. clamping voltage Max. idle current 3000 2000 ENF681D14A ENF621D14A Voltage [V] ENF511D14A 1000 900 800 700 600 500 400 EN F 68 EN 1D 1 F 62 F5 300 EN 200 -6 10 10 -5 4A 1D1 4A 14 1 1D A 10 -4 10 -3 10 -2 10 -1 Current[A] 10 0 10 1 10 2 10 3 4500 3 FUJI Ceramic Surge Absorbers Z-TRAP ENF series 220 to 680V (Varistor voltage) Pulse lifetime ratings 07A series (ENF221D07A to ENF471D07A) 05A series (ENF221D05A to ENF471D05A) 10000 1000 lse 2 pu 12 10 4 10 5 10 6 2 3 10 10 10 l se pu 1- Reted peak pulse current [A] 1000 10 Rated peak pluse current [A] 100 10 100 10 2 10 3 10 4 10 5 10 6 10 1 0.1 20 100 1000 1 10000 20 100 1000 Impulse duration [us] 10000 Impulse duretion [us] 14A series (ENF221D14A to ENF471D14A) 10A series (ENF221D10A to ENF471D10A) 10000 10000 1pu lse e ls pu 1- Rated peak pulse current [A] 2 Rated peak pulse current [A] 1000 10 10 100 10 2 3 10 4 10 5 10 6 10 1 2 1000 10 100 10 2 10 3 10 4 10 5 10 6 10 20 100 1000 Impulse duration [us] 10000 1 20 100 1000 10000 Impulse duration [us] 4 FUJI Ceramic Surge Absorbers Z-TRAP ENF series 220 to 680V (Varistor voltage) 14A series (ENF511D14A to ENF681D14A) 10A series (ENF511D10A to ENF681D10A) 10000 10000 1pu lse Rated peak pulse current [A] 2 2 Rated peak pulse current [A] 1000 e ls pu 1- 1000 10 100 10 2 10 3 10 4 10 5 10 6 100 10 2 10 3 10 4 10 5 10 6 10 10 1 10 1 20 100 1000 Impulse duration [us] 10000 20 100 1000 10000 Impulse duration [us] 5 FUJI Ceramic Surge Absorbers Z-TRAP ENF series 220 to 680V (Varistor voltage) Dimensions, mm .
