The ZNRV14241U is a transient/surge absorber from Panasonic's ZNR® V series of varistors. These voltage-dependent, non-linear resistors offer excellent transient voltage suppression (TVS) characteristics, making them suitable for protecting sensitive electronic equipment from voltage surges caused by lightning, inductive load switching, and electrostatic discharge (ESD).

Applications

• Consumer Electronics: Protection of televisions, audio equipment, and other home appliances.
• Industrial Equipment: Surge protection for power supplies, motor controls, and programmable logic controllers (PLCs).
• Telecommunications: Protecting communication lines and equipment from lightning strikes and power surges.
• Power Supplies: Input and output protection in AC/DC and DC/DC power supplies.
• LED Lighting: Surge protection for LED drivers and lighting fixtures.

Features

• High Surge Current Capability: Designed to withstand high surge currents without degradation.
• Fast Response Time: Reacts quickly to transient voltage surges, minimizing the risk of damage to protected components.
• Low Clamping Voltage: Limits the voltage across the protected circuit to a safe level during a surge event.
• Wide Operating Voltage Range: Suitable for a variety of applications with different voltage requirements.
• RoHS Compliant: Environmentally friendly and compliant with RoHS directives.

Benefits

• Enhanced Equipment Reliability: Protects sensitive electronic components from damage caused by voltage surges, increasing the lifespan and reliability of the equipment.
• Reduced Downtime: Minimizes equipment downtime due to surge-related failures.
• Improved Safety: Protects users from electrical hazards caused by voltage surges.
• Cost Savings: Reduces the need for costly repairs and replacements of damaged equipment.
• Peace of Mind: Provides reliable surge protection for valuable electronic assets.

Technical Specifications (Typical):

• Varistor Voltage: Approximately 240V (check datasheet for precise value)
• Maximum Surge Current: Consult datasheet for specific surge current rating (typically several kA)
• Operating Temperature Range: Usually -40°C to +85°C
• Case Size: Disc type with lead wires

Additional Details: The ZNRV14241U is typically used in parallel with the circuit to be protected. When a transient voltage surge occurs, the varistor's resistance rapidly decreases, diverting the surge current away from the protected components. It is crucial to consult the manufacturer's datasheet for detailed specifications and application guidelines to ensure proper selection and implementation of the ZNRV14241U.
