New Arrival Biggest 938 Series Plastic Shell Super Slow Blow Micro Subminiature Fuse AC 250V 300V T 4A 5A CQC CB UL
Application
Over-current protection.Its main applications are for consumer electronics, LED drivers, power supplies, battery chargers and controllers for industrial use.
GENERAL INFORMATION
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.
