The MSMD075-33V is a resettable fuse, also known as a Polymer Positive Temperature Coefficient (PPTC) device, manufactured by TECHFUSE. This component provides overcurrent and short-circuit protection for electronic circuits. It operates by limiting the current during a fault condition and automatically resetting when the fault is removed and power is cycled.

Applications:

• USB Power Protection
• Power Supplies
• Electronic Toys
• Game Consoles
• General Electronic Equipment

Features:

• Resettable: Automatically resets after the fault is cleared.
• Surface Mount: Designed for easy assembly on PCBs.
• Fast Tripping: Quick response to overcurrent events.
• Low Resistance: Minimal power dissipation during normal operation.
• Compact Size: Space-saving design for dense circuit boards.

Benefits:

• Reliable Overcurrent Protection: Prevents damage from excessive current.
