Direct Electronics Tech Co. Ltd 's series of fusible resistors feature an insulation resistance of 1 gigaohms and operating temperature range of -40C to 240C, making it suitable for use in voltage maintenance and overload protection applications found in TV receivers, battery chargers, and CPU coolers.

The resistors are available in metal film or carbon film (FRN), wirewound (FKN), and cerment (FSQ) types, and act as resistors during normal conditions or as a fuse under fault conditions.

Rated wattage is 0.25W to 3W for the FRN type, 1W to 6W for the FKM type, or 2W to 10W for the FSQ type. Resistance ranges from 0.22 ohms to 100 kiloohms (FRN), 0.1 ohms to 250 ohms (FKN), or 0.1 ohms to 500 ohms (FSQ). They have a dielectric withstand voltage of 300V, 350V, 500V, or 1kV.
