STANDARD SERIES
INTRODUCTION
The Standard Series is our broadest and most
comprehensive line of radial-leaded varistors. These
components consist of wire leads and have nominal
disk diameters from 5mm to 25mm. They are available
with maximum continuous operating voltages (MCOV)
ranging from 11VAC to 1000VAC (up to 1500VAC upon
request).
The Standard Series is designed to handle most low
and medium power applications requiring throughhole components. Most sizes are available in Tape and
Reel and ammo pack.
STYLE DESIGNATION
The Maida Style Number is the typical means to
identify our components when ordered. The style
number identifies several parameters that are
important for the characteristics of the device. An
alternative ordering method, if known, is by our Item
Number. The Item Number is a unique designation for
each MOV design, whereas numerous MOV designs
may be made with the same Maida Style Number.
The following example is the standard part numbering
system when ordering our Standard Series
components by the Maida Style Number:
STANDARD MARKING
Minimum marking shall consist of an
abbreviated style designation and, when
space is available, the manufacturer’s
initials or company logo.
For example:
MDC
Z131
20UL
Where:
MDC - Company Initials
ZZinc Oxide Varistor
131 - AC Voltage rating (130VAC)
20 Rating code
UL UL recognition, if applicable
A manufacturing date code and/or
special markings are available upon
request.
Other safety agency designations are
included where applicable.

LEAD CODES and TAPE & REEL
LEAD CODES
The Maida Development Company prides itself on its ability to manufacture wire leaded devices to meet
almost every request of its customers. The following table depicts common varieties of leads that are
presently supplied. It should be noted that the dimensions (such as the X, Y, Z, height, lead length, epoxy
“pant leg”, wire diameter, etc.) can be modified on any the items shown to meet almost any request.
Maida is also capable of supplying the various lead forms in either right-hand or left-hand configurations.
For any inquiries regarding specific lead forms please contact us.
NOTE: The images shown depict a round varistor only. However, any lead configuration can be obtained
on either round or square varistors.
TAPE & REEL
The Maida Development Company MOV’s are available in Bulk, Tape & Reel, or Ammo Pack packaging
formats. All Tape & Reel and Ammo Pack part numbers are designated by suffixing the Maida style
number with a T followed by a 1-2 digit alphanumeric code. The codes are generally given to indicate
whether the packaging is either Ammo Pack or Tape & Reel, the typical lead spacing of the varistor, the
lead style, the wire gauge (or wire diameter), and the taping pitch.
Generally, through-hole varistors with a lead spacing of 0.394”, or less, and a nominal disc diameter of
20mm, or less, can be taped. Larger diameters and/or lead spacing’s may be offered taped; however
customers should contact us for confirmation.
All SMD Series, SMV Series, Encapsulated MOV Series, and MLV Series are provided Tape & Reel. For
bulk packaging please contact us.
Maida’s taping specifications comply with the requirements of the EIA taping standard. Configurations are
available to meet almost any request.
Detailed drawings for all taping codes are available upon request.
