Surge Absorbers
MMC's unique surge protection devices are constructed
using laser cut mirco-gap technology. To insure the highest quality devices, MMC assembles
them in a Category 2 clean room environment and utilizes an inert gas to fill the glass
encapsulant. This gas provides a consistant "atmosphere" for the discharge.
Surge devices are predominantly leaded and have an axial
form. Basedd on the application, several options are available. ESD type
protection can start as low as 140V arc-over and direct surge protection can go as high as
4500V arc-over. Certain devices are UL/CSA listed and one specific design is
uniquely qualified to service the T/R line for UL 1449 protection of communication units.
DIA Surge Series [DA53,DSA,DSP,DSS]
[DA53 Series]
. Small size. (Ø 5.3mm Length 10mm)
. Allows performing the AC with standing voltage test.
. Used to protect power supplies.
. Quick response for surge voltage and low limiting
voltage.
. Small Capacitance and excellent insulation
resistance.
. Stable for repeated electrostatic test conditions and
environmental fluctuation.
. No polarity.
. No dark effect.
Surge Absorber [DSA]
. The Models of this series are extensively used as
surge-protecting elements for electronic equipment in
low-voltage and low-current circuits such as
telecommunication equipment and sensor lines.
. Excellent for protecting signal lines that require
low
capacitance.
. The DSA-A-type combined with a cement resistor or
varistor
can be used as surge-protecting elements in power supplies.
. Allows performing the AC withstanding voltage test
without
removal of the surge absorber.
Surge Protector [DSP]
. Car radio, radio cassette, wireless, new media.
. Protection from electrostatic discharge in a CRT
display or
monitor TV. (Except DSP-141N)
. Protection against electrostatic discharge.
Surge Suppressor [DSS]
. Surge protection for telephone lines.
(telephone,modem,facsimile etc.)
. Surge protection for telecommuniations lines.
(computer etc.)
. Some models are recognized by UL.
