fuse.html" target="_blank">Littelfuse disposable fuse products are used in various electronic equipment to ensure the safe and stable operation of the circuit, the following is a detailed introduction of LITTELFUSE 0287 and 0452 series disposable fuse, especially for models 0452001.MRL and 0287030.PXCN specific parameters and applications are analyzed.
0452001.MRL belongs to LITTELFUSE's 0452 series of disposable fuses in size 6125. This patch type fuse is compact and suitable for space-constrained electronic equipment. The fuse has a rated current value of 1A, which means that it is able to safely conduct 1 amp of current under normal operating conditions. When the current exceeds this value, the wire inside the fuse will be blown due to overheating, thus cutting off the circuit. Its rated voltage is AC/DC125V, indicating that it can operate at either AC or DC voltages, with a maximum voltage of no more than 125 volts. 0452001. The MRL is mounted on a patch, which makes it easy to integrate onto a printed circuit board (PCB). The chip fuse has the advantages of small size, light weight, easy installation, etc., which is very suitable for the high-density wiring needs of modern electronic equipment.
0287030.PXCN is the disposable fuse of LITTELFUSE 0287 series, its size is larger, 19*18.8*5.1mm, this size is more suitable for the application scenario that needs to withstand large current and voltage. The fuse has a rated current value of up to 30A, its rated voltage is DC32V, mainly suitable for direct current circuits, and can operate safely at a voltage of up to 32 volts. For any fuse, its rated voltage and current value are very important parameters. When selecting a fuse, it is necessary to ensure that the specifications of the selected product match the requirements of the circuit to prevent damage and safety hazards caused by overload or short circuit.
MRL due to its small size and moderate current and voltage specifications, fuses are widely used in consumer electronics, communication equipment, computer peripherals and other fields. The 0287030.PXCN fuse has a high current carrying capacity and moderate voltage specifications, and is usually used in industrial equipment, automotive electronics, power systems and other fields, in these applications, can provide reliable circuit protection to ensure that the equipment can be safely turned off or disconnected from the power supply in abnormal circumstances.
