urface Mount

6. AC Voltage Rating

Two significant figures plus nu mber

of zeroes that follow, i.e. 131 is 130 VAC

7. Packaging Code

T6 – Tape and Reel

B – Bulk

The SMT Series, designed for surface mount

applications, are small varistors manufactured in a

leadless monoblock form. The SMT Series varistors

have significantly lower profiles than our radial-

leaded devices, thus reducing PC board design

requirements. They are available with maximum

continuous operating voltages (MCOV) ranging from

10VAC to 600VAC.

SMT Series are typically packaged in Tape and Reel

packaging. To order in an alternate packaging

scheme, please see the order code below or contact

us.

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 SMT Series

components by the Maida Style Number:
