Their dedication to quality is reflected in their IATF16949, ISO13485, ISO9001, and ISO14001 certifications. Today, we’re excited to highlight the wide terminal, current-sensing metal chip resistor from Viking Tech – a component designed to meet the growing demands of modern electronics.
Current-Sensing Metal Chip Resistor from Viking Tech
Viking Tech’s CSMW series of Current Sensing Metal Chip Resistors (Wide Terminal) is engineered to address the growing power, thermal, and reliability requirements of modern industrial and automotive electronics while keeping the size to a minimum. Also referred to as shunt resistors, these components play a vital role in electronic circuits by accurately measuring current flow and converting it into a corresponding voltage. This functionality is essential for enhancing efficiency and ensuring the effective performance of various devices. The CSMW series stands out with its low-value, high-power characteristics, offering resistance values as low as 3mR (3 milliohms) within impressively compact sizes, including the notably small 0306 package.
The CSMW series resistors feature a wide terminal design that plays a crucial role in enhancing heat dissipation to the PCB, which in turn significantly boosts their power rating. This is particularly vital as the trend in electronics moves toward higher power densities. Additionally, the wide terminals ensure excellent thermal cycling performance, which is essential for reliability in demanding conditions. Built with a metal foil construction, these resistors provide a stable and low Temperature Coefficient of Resistance (TCR), ensuring their performance remains consistent across a broad temperature range of -55°C to 175°C. They are Pb-free and comply with RoHS standards, making them suitable for use in stringent automotive applications as they also meet AEC-Q200 requirements. To further enhance their reliability in tough environments, these resistors are inherently anti-sulfur.
Viking Tech has utilized its vast expertise in resistor manufacturing to develop a product that not only fulfills but surpasses the requirements of contemporary electronic design, providing a strong, dependable, and high-performance solution for current sensing applications.
