The TVR10681 is a varistor manufactured by TKS. As a voltage-dependent resistor (VDR), its primary function is to protect electronic circuits from transient voltage surges, spikes, and other overvoltage events. By rapidly decreasing its resistance when subjected to high voltage, the varistor diverts the surge current away from sensitive components, thus preventing damage.

Applications

• Power Supplies: Providing overvoltage protection for power supply units.
• Consumer Electronics: Protecting devices such as TVs, stereos, and appliances.
• Industrial Automation: Safeguarding control systems and industrial equipment from electrical transients.
• Telecommunications Equipment: Protecting phone lines and communication infrastructure.
• Surge Protection Devices: Employed within surge protectors to enhance their protective capabilities.

Features

• High Surge Current Capability: Able to withstand significant surge currents without failure or degradation.
• Fast Response Time: Reacts quickly to voltage transients, providing immediate protection.
• Wide Operating Voltage Range: Suitable for a wide range of voltage levels and applications.
• Compact Size: Allows for easy integration into densely populated circuit boards.
• RoHS Compliance: Meets requirements for the restriction of hazardous substances.

Benefits

• Enhanced Circuit Protection: Safeguards electronic circuits from damage due to overvoltage events.
• Improved System Reliability: Increases the lifespan and reliability of electronic devices.
• Reduced Downtime: Minimizes equipment failures and downtime caused by voltage transients.
• Cost-Effective Solution: Provides a cost-effective method for protecting electronic circuits.
