Token Electronics equipped with (FLM) alloy shunt on its current sensing surface mount devices. It adopts the design of folding terminals outward and inward. Nickel-copper or manganese-copper alloy stamping is used to maintain the superior electrical characteristics of the surface mounting structure. It has the characteristics of pulse resistance and high precision.
Unlike other manufacturers of metal alloy current detection resistors, Token metal alloy power chips (FLM) have a number of advantages. Power can reach 4W, 5W, and 7W. The temperature coefficient TCR (20 - 50) ppm, tolerance accuracy 1%, 2%, and 5%, is used to improve the measurement accuracy. The resistance value is as low as 0.0002Ω, which is the first choice for high-end current sensing and sampling applications.
The (FLM) device is applicable to all types of voltage dividers, current detection and pulse applications in power management, such as sensors and transducers; VRM for notebook computers, DC/DC converters for servers, management and safety of lithium ion batteries; industrial instrumentation; and high current applications in the automotive market, such as audio, transmission, anti-lock braking, and engines.
Token Electronics adopts modern technology and production methods, constantly upgrades production equipment, provides complete low resistance current detection components, and all aspects of current sensing shunt product and application information.
The (FLM) device is available in bulk packaging and is RoHS compliant and lead free. For non-standard technical requirements and special applications, contact us with your specific needs.
