Notes

(1) The products are certified according to cULus (E332800), and VDE (40051495). 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 (Ip) and pulse width t2 (virtual time of half Ip value). If Vp is the clamping

voltage corresponding to Ip, the energy absorbed in the varistor is determined by the formula:

where K is dependent on the value of t2 (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.
