12.4x6.4x9.8mm Plastic Shell Super Time-Lag Subminiature Fuse AC 250V 300V T 4A 5A For LED Driver Circuit

Description

Following electronic product specifications apply to fuses of the 938 series. The 938 series is a super time lag type subminiature fuse for 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.
