On-Board Type (DC) EMI Suppression Filters (EMIFILr)

Chip Varistors VCM18R/VCM21R Series

0.4±0.2

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.

0.8±0.2

1.6±0.2

VCM18R absorbs surge voltage, results to protect

circuit simply by inserting between surge entrance

line and ground line.

VCM18R Series

in mm

■ Features

0.4±0.2

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.

2.0±0.3

1.25±0.3

4. VCM has capacitance and functions as by-pass

capacitor for noise suppression.

in mm

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.

■ 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)
