Chip Resistor ■ INTRODUCTION Chip resistors are general passive component which is useful for derating voltage, current controlling in circuit and surface mounting is available. Samsung electro mechanics also manufactures a wide range of chip resistors such as general, precision, trimmable and low ohms and so on. Production is increasing with demand for small size & light weight of set product. We provide ultra-small, high-reliability, high-stability resistors.
