STANDARD MARKING

Minimum marking shall consist of an

abbreviated style designation and, when

space is available, the manufacturer’s

initials or company logo.

Example:

Where:

MDC - Company Initials

R65 – Square Disc Diameter

131 – AC Voltage rating (130VAC)

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.

The Low Profile Series compliments our Standard

Series as our square disc, radial-leaded varistors.

These components consist of wire leads and have

nominal disk diameters from 12mm to 25mm. They

are available with maximum continuous operating

voltages (MCOV) ranging from 130VAC to 1000VAC.

The Low Profile Series are designed to fit into spaces

that Standard Series electrically equivalents are

unable to fit. 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 following example is the standard part

numbering system when ordering our Low Profile

Series components by the Maida Style Number:

Typical

Maida Nominal Minimum Cap.
