Over-current protection.Its main applications are for consumer electronics, LED drivers, power supplies, battery chargers and controllers for industrial use.





The 938 series provides protection for printed circuit boards used in a large variety of applications that need fuses with time-delay, low breaking capacity. The sub-miniature device is constructed of a plastic cap and base with a tin plated copper lead wire. It offers excellent mounting characteristics and is 100% tested for cold resistance.


Detailed Features

• Subminiature fuse with time delay, low breaking capacity.
• Small, rectangular and leaded design minimizes board space and eliminates the need for additional mounting components.
• Plastic cap / black thermoplastic fuse body.
• 0.6mm lead wires made of tin plated copper.
• Protection against harmful over-currents in primary and secondary applications.
• Lead-free, Halogen-free, RoHS compliant.
• Designed according to IEC 60127-4.
