The JFC2410-2120TS series of surface mount fuses, manufactured by JDT, are 2410 size RoHS compliant components rated for 2.1A, 20V, 1mOhm. They are designed to protect components such as DC/DC converters, system and power supplies and other integrated circuits from electrical overcurrent when they are damaged from prolonged excessive current exposure. The JFC2410-2120TS fuses feature a radial-leaded design and are constructed out of tinned copper and brass with aluminum casing, making them suitable for multiple-layer circuit board mounting. The fuses are rated for temperatures between -40 to +85°C for continuous operations and have a breaking capacity of 200A. They have fast response times of less than 6ms for 10A overcurrents and with their low internal resistance, help improve system efficiency.
