roducts Overview

MLCC (Multi-Layer Ceramic Capacitor)

SAMWHA provides MLCCs in various sizes (0603~9595<mm>, 0201~3838
<inch>)and temperature characteristics (C0G, X7R, X5R, Y5V).

MLV (Multi-Layer Chip Varistor)

Chip Varistors are widely used for problems of transient over-voltage caused
by ESD (Electro Static Discharge).

Chip Bead/Inductor

Ferrite paste and electric conductor paste are layered and sintered into a
monolithic structure to form an inductor with an excellent magnetic shield and
high reliability. 

DCC (Disc Ceramic Capacitor)

SAMWHA Provides 3 major types of DCCs, Temperature Compensation
Type, High dielectric Constant Type and Safety recognized Type.

SAMWHA high voltage MLCC products with the temperature characteristics of C0G and X7R are designed  for

commercial and industrial applications.  The products are applied to DC-DC converters and ballast circuit to

reduce ripple noise and diverting potentially unsafe transients in various sizes with working voltage up to DC 7kV.

These high voltage capacitors feature a special internal electrode design which has capacitor network to reduce

voltage concentrations by distributing voltage throughout the entire capacitor.
