Samsung Electro-Mechanics Current Sensing Chip Resistors

Chip resistors are manufactured in a rectangular parallelepiped shape to ensure that they can be surface-mounted. These resistors are all-around passive components that are most widely used in electronic circuits together with capacitors. They regulate current and drop voltage in circuits. New products are continuously developed as sets are made smaller in size and have advanced functions. General Features High power and low resistance of the thick film printing method Realizes ultralow resistance through in-house resistance pasting technology Low TCR characterisics Use of 100% lead-free soldering Compliance with EU RoHS Application Circuits of electronic equipment Home appliances, N-PCs, and tablet PCs Mobile and communication devices Why Samsung Features of Current Sensing Resistors By using the thick film method, variouslow-ohm (CSR) series that have high power and low TCR characteristics are manufactured. The products are applied for PCM (battery packs), PMIC (UD panels), power, WPT, ESL tags, N-PCs, ultrabook computers, tablet computers, networks, and current sensing.
