The B72650M111K72 is a metal oxide varistor (MOV) from EPCOS (TDK), designed for overvoltage protection. As a transient voltage suppressor (TVS), it protects sensitive electronic circuits from damage caused by voltage surges and spikes.

Applications:

• Power supplies: Protecting AC/DC and DC/DC power supplies from line transients and surges.
• Lighting systems: Safeguarding LED drivers and ballasts from voltage spikes.
• Industrial equipment: Protecting motors, controllers, and other industrial automation components.
• Consumer electronics: Protecting TVs, computers, and other home appliances from power line disturbances.
• Telecommunications equipment: Ensuring the reliability of network infrastructure by protecting against voltage transients.

Features:

• High surge current capability: Withstands high surge currents without failure.
• Fast response time: Quickly clamps transient voltages to protect sensitive components.
• Low clamping voltage: Limits the voltage across the protected circuit to a safe level.
• Wide operating voltage range: Suitable for various voltage levels and applications.
• Compact size: Facilitates easy integration into circuit boards.
• RoHS compliant: Meets environmental standards for restricted substances.

Benefits:

• Enhanced equipment reliability: Prevents damage to sensitive components from voltage surges.
• Extended product lifespan: Reduces the risk of premature failure due to overvoltage events.
• Reduced downtime: Minimizes equipment malfunctions and service interruptions.
• Improved safety: Protects users from electrical hazards.
• Cost-effective protection: Provides reliable overvoltage protection at a competitive price.
