Notes
(1)
The products are certified according to (c)UL (E332800), VDE (40002622) and CSA (219883)
(2)
The sinusoidal voltage is assumed as the normal operating condition. 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 IEC 61051.
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 (I
p
) and pulse width t
2
(virtual time of half I
p
value, following IEC 60060-2,
section 6 ). If V
p
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 t
2
when the value of t
1
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 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 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 H
0
= 16 mm (tape and reel/ammo)
H for straight leads with flange and H
0
= 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)
(7)
All varistors are recognized under VZAC2 surge protective devices, components type 4 as specified in UL 1449 edition 3 for operation in ambient
temperatures up to 85 °C. The parts with indication type 2 or 3 SPD’s, are tested and certified to be used in type 2 or 3 SPD applications with
operating ambient temperatures up to 85 °C. The final acceptance of the component is dependent upon its installation and use in complete
equipment submitted to underwriters laboratories Inc.
