On-Board Type (DC) EMI Suppression Filters (EMIFILr)
Chip Varistors VCM18R/VCM21R Series
The surge test on electronic equipment tends to be
popular because of the regulation for immunity. This
situation requires surge absorb components smaller
dimension, lower cost and higher performance.
VCM18R is designed as absorbing devices which, with
MURATA's advanced technic, has higher performance in
spite of its small dimension.
VCM18R absorbs surge voltage, results to protect
circuit simply by inserting between surge entrance
line and ground line.
s Features
1. It is effective in high density packaging, because
of smaller dimension than diode which is generally
used as surge countermeasure devices.
2. The small clamping voltage ratio enables effective
absorption of surge noise.
3. The nickel barrier structure of the external
electrodes provides excellent solder heat
resistance. Both flow and reflow soldering methods
can be applied.
4. VCM has capacitance and functions as by-pass
capacitor for noise suppression.
5. The large peak current of VCM21R, up to 150A,
enables high reliability against surge.
6. VCM21R can be applied to ISO-7637-1/Test pulse
condition 1-4 and 6.
s Applications
Surge absorption in communication ports such as
RS-232C
Motor/relay noise absorption
Electro static protection in I/O port of computers
ESD protection for Input/Output interface of compact
size digital equipment such as cellular phone,
digital camera.(VCM18R Series)
