MOV Transient Voltage Suppressors
Description
CKE, Inc. features two radial leaded MOV product lines:
❚Standard Series
❚High Energy Series
CKE, Inc. also features three High Energy Special Package MOV products:
❚PA Series
❚Z33M & Z40M Series
❚EH Series
Our Standard Series will continue to offer the optimum value in quality and economy. These parts are
presented in Tables 1 and 2 of the catalog.
The High Energy Series offers a premium quality in a higher density package, allowing a reduction to the
next lower mm size from standard MOV ratings. This can be allowed because the current and energy
ratings have increases of up to 50% over the standard series MOVs. For specifications please contact
CKE, Inc.
CKE, Inc. identifies its Z-MOV product line by using various characters and actual electrical specifications
that are incorporated into the part number. CKE uses a “Z” prefixas its identity for all Z-MOV products
and an “H” suffixto identify the High Energy Series parts. All parts 7 mm and larger with a voltage
rating of 130 V and up have the RMS voltage ratings in their part number. All 5 mm parts
and those with voltages lower than 130 RMS are identified by the mm size and the
peak nominal clamping volts at the 1 milliamp level.
CKE, Inc. uses the latest in manufacturing technology in the production of
our varistors. Both the Standard Series and High Energy Series MOV parts
with a (Underwriters Laboratories Recognized Component Mark)
conform to UL1414, UL1449 and CSA class 2221 01. All of CKE’s
line voltage parts are UL recognizedand listed on File E90510 (M).
Parameter Definitions
Maximum Applied Voltage — Maximum AC RMS value of a
sine wave or maximum DC value “filtered.”
Varistor Voltage — Voltage between terminals when 1 mA
of DC current is applied (0.1 mA for 5 mm parts).
Energy — Maximum energy of two 2 ms pulses at 1 minute
interval which cause > 10% change in varistor voltage.
Maximum Clamping (VI) — Peak voltage value for peak
current applied with 8 µs rise time, 20 µs decay to 50%
value of the current.
Maximum Power Dissipation Ratings
5 mm 0.1 Watt Z33M 1.5 Watt
7 mm 0.25 Watt Z40M 2.0 Watt
10 mm 0.4 Watt EH4 1.5 Watt
14 mm 0.6 Watt EH5 1.75 Watt
20 mm 1 Watt EH6 2.0 Watt
Selection Procedure
MOVs are transient voltage clipping devices and cannot regulate the line voltage. Therefore, there are
important steps to follow in selecting the correct MOV:
1. The open circuit or surge voltage must not exceed the maximum applied continuous voltage.
2. The energy rating of the varistor, in joules, must not be exceeded. The transient energy rating
may be calculated by W = 1/2LI2, where “L” is the inductance of the component or the
system inductance responsible for the transient. “I” would be the current flowing in the
inductance during the interruption.
3. The peak current interrupted will determine the clamping voltage. Review the VI
characteristics to determine if the MOV selected will clamp at the maximum peak voltage
required. A larger MOV will provide a lower clamping voltage.
Note:
Higher voltage MOV selection is acceptable as long as the maximum clamping voltage meets your
requirements. Higher energy ratings are also acceptable provided the physical space is available.
Under no circumstances is a lower voltage rating MOV to be used.
