Description
The SPT 5×20 is a miniature fuse with dimensions of 5 x 20 mm. It uses a time-lag delay characteristic (denoted as ‘T’) and is designed to be used in applications requiring 250VAC or 115 V to 300 VDC. The ceramic tube construction facilitates a high breaking capacity (H), signifying robust interruption capabilities in the event of overcurrent events.
Applications
The SPT 5×20 is suited for primary protection within power supply systems of various electronic devices. It is commonly used in power supply adapters for laptops, and in Switching Mode Power Supply (SMPS) systems for televisions and DVD players.
Technical Data
The fuse’s voltage rating is set at 250VAC and it can support DC systems ranging from 115 to 300VDC. It can handle rated currents between 0.5 and 16 Amperes. The SPT 5×20 exhibits a breaking capacity between 500A and 1500A, making it capable of interrupting significant fault currents. Its operational temperature range is broad, from -55°C to +125°C, falling under the climatic category 55/125/21 as per IEC 60068 standards. The fuse’s construction materials include a ceramic tube and endcaps made from nickel-plated copper alloy, providing durability and stable performance over its lifetime. Its light unit weight of 1.16 grams makes it suitable for compact designs. For storage, the recommended conditions are a temperature range of -5°C to 60°C with a maximum relative humidity of 70%.
