Chip Resistor is a passive electronic component that limits the flow of Direct Current (DC) and Alternating Current (AC). Among its properties is to lower the voltage or maintain the current constant inside an electronic circuit. Resistance basically follows Ohm’s Low, while its Resistance Value is acquired through the combination of materials between high & low electrical conductivity being used together. The main resistor materials for Chip Resistor are Ag, Pd, RuO₂, CuNi, etc., which are used to manufacture general resistors, array resistors, ultra-low resistors, sulfur-resistant products, high-power products, and eco-friendly products.

Anti Sulfur Resistor
Chip Resistor mainly uses silver (Ag) as its electrode material, but silver is easily corroded by sulfur (S) and gradually turns into silver sulfide (Ag₂S). Silver sulfide is an insulator and prevents current flow between both terminals of a resistor. Therefore, it is necessary for an electronic device used under a harsh environment to apply a resistor with sulfur resistance. Samsung Electro-Mechanics supplies Chip Resistor with sulfur resistance by developing materials that are resistant to sulfur corrosion with its unique materials and design technology.
- Applications
- long-term reliability electronic devices, server systems (memory modules/HDDs), network equipment
- 1. Electrode (Ag)
