Notes
(1)
The products are certified according to cULus (E332800), and VDE (40013495). See Agency Approval section on page1 for certificate
download section
(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 characterized by peak current (I
p
) and pulse width t
2
(virtual time of half I
p
value). If Vp is the clamping
voltage corresponding to I
p
, the energy absorbed in the varistor is determined by the formula:
where K is dependent on the value of t
2
(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 K for kinked leads (bulk only)
A for tape and ammopack 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 UL1449 edition 4 recognized as SPD type 5 (component level) for operating temperatures up to 125 °C The varistors may
be used in other SPD types as 2, 3, or 4 depending on the indicated nominal discharge current ratings. The final acceptance of the
component is dependent upon its installation and use in complete equipment submitted to Underwriters Laboratories Inc.
