If a non-sinusoidal voltage is present, type selection should be based on multiplying the peak voltage by a factor of 0.707. (3) The voltage measured at 1 mA meets the requirements of “paragraph 4.3 of CECC specification 42000”. The tolerance on the voltage at 1 mA is ± 10 %. (4) High energy surges are generally of longer duration. The maximum energy for one pulse of 10 x 1000 µs is given as a reference for longer duration pulses. This pulse can be characterised by peak current (Ip) and pulse width t2 (virtual time of half Ip value, following “IEC 60060-2, section 6” ). If Vp is the clamping voltage corresponding to Ip, the energy absorbed in the varistor is determined by the formula: where: a) K is dependent on the value of t2 when the value of t1 is between 8 µs and 10 µs; see Peak Current as a Function of Pulse Width drawing (5) A current wave of 8 x 20 µs (requirement of “paragraph B.2.10.1 of CECC specification 42000” ) is used as a standard for pulse current and clamping voltage ratings. The maximum non-repetitive transient current is given for one pulse applied during the life of the component. (6) For composition of the 12NC part number replace “x” and “y” by figures from the sections “Varistors in Bulk”, “Varistors on Tape in Ammopack” and “Varistors on Tape on Reel”. (7) For composition of the SAP part number: Replace “x” by B for bulk type Replace “y” by S for straight leads T for tape and reel F for straight leads with flange (bulk only) A for tape and ammopack G for straight leads with flange and H0 = 16 mm (tape and reel/ammo) H for straight leads with flange and H0 = 18.25 mm (tape and reel/ammo) K for kinked leads (bulk only) L for kinked leads with H0 = 16 mm (tape and reel/ammo) M for kinked leads with H0 = 18.25 mm (tape and reel/ammo) 420 560 680 1100 5.0 20.0 400 35 2381 592 x421y VDRS05C420xyE 1120 10.0 56.0 1200 85 2381 593 x421y VDRS07H420xyE 1120 25.0 73.0 2500 165 2381 594 x421y VDRS10P420xyE 1120 50.0 120.0 4500 250 2381 595 x421y VDRS14T420xyE 1120 100.0 344.0 6500 510 2381 596 x421y VDRS20W420ByE 460 615 750 1200 5.0 21.0 400 30 2381 592 x461y VDRS05C460xyE 1240 10.0 63.0 1200 75 2381 593 x461y VDRS07H460xyE 1240 25.0 82.0 2500 150 2381 594 x461y VDRS10P460xyE 1240 50.0 135.0 4500 225 2381 595 x461y VDRS14T460xyE 1240 100.0 360.0 6500 460 2381 596 x461y VDRS20W460ByE 510 670 820 1355 25.0 89.0 2500 135 2381 594 x511y VDRS10P510xyE 1355 50.0 145.0 4500 220 2381 595 x511y VDRS14T510xyE 1355 100.0 376.0 6500 450 2381 596 x511y VDRS20W510ByE 550 745 910 1500 25.0 98.0 2500 120 2381 594 x551y VDRS10P550xyE 1500 50.0 160.0 4500 180 2381 595 x551y VDRS14T550xyE 1500 100.0 408.0 6500 370 2381 596 x551y VDRS20W550ByE 625 825 1000 1650 100.0 448.0 6500 320 2381 596 x621y VDRS20W625ByE 680 895 1100 1815 100.0 496.0 6500 270 2381 596 x681y VDRS20W680ByE ELECTRICAL DATA AND ORDERING INFORMATION MAXIMUM CONTINUOUS VOLTAGE VOLTAGE (3) at 1 mA MAXIMUM VOLTAGE at STATED CURRENT MAXIMUM ENERGY (4) (10 x 1000 µs) MAXIMUM NON-REP.
