Bi-directional 5032 SM7 Plastic Encapsulated Surface Mount Metal Oxide Varistor S511KB 07D511K For AC Line Protection

 

 

Notice

 

S Series is a plastic-encapsulated surface-mount metal oxide varistor (MOV) transient voltage surge suppressor that is designed to be operated continuously across AC power lines.

The series comprises a Nylon molded package with tin plated lead frame for soldering to board. The surface mount SM7 Series is based on radial 7mm internal varistor element with similar characteristics to the Littelfuse LA / ZA series of varistor.

 

 

 

Features

 

  • Electrical equivalent to leaded types LA/ZA series
  • AC Voltage Rating 115 V to 510VAC rms
  • No De-Rating up to 85°C ambient
  • Good solderability
  • Available in tape and reel
  • Application of AC power meters
  • Excellent non-linearity voltage
  • Symmetric V-l characteristics
  • Great withstanding surge current (2000A/cm2)

HOW TO SELECT A VARISTOR(ONLY REFERENCE)

 

A: Varistor voltage

Varistor Voltage should be more than the operating voltage in over protective
is shown as the following.
V1ma=a·v/b·c
a -power Voltage ripple coefficient usually 1.2
v -DC Voltage (significant value only AC power)
b -Tolerance usually take 0.85
c -Ageing coefficient usually take 0.9

 

B:Withstanding surge current
In general, withstanding surge current is max,Pulse current value which determined by test conditions
Such as wave-shape, amplitude and intermal time, when the amplitude decrease to 50% of the initial,
It should be increased to 2 times of the initial in order to keep the life
Sbsorbed by the varistor should be less than max. withstanding surge current
