MOV-14D681KMetal Oxide Varistor - Thakor (VCRR)

Product/ServiceDescription

The MOV-14D681K is a Metal Oxide Varistor(MOV) manufactured by Thakor under the VCRR series. It is a voltage-dependentresistor commonly used to protect electronic devices and circuits from voltagespikes or surges by clamping transient voltages to safe levels. The "681 inits part number refers to its nominal voltage rating of 680V, and the "14Dindicates a 14mm disk diameter.

Uses andApplications

1. Surge Protection:
• Protects sensitive electronic components from voltage spikes and transient surges caused by lightning strikes, power fluctuations, or switching events.
• Widely used in industrial equipment, home appliances, and power distribution systems.
2. Circuit Protection:
• Prevents overvoltage damage in power supplies, telecommunications devices, and automotive electronics.
3. Suppression of Transient Energy:
• Absorbs and dissipates excess transient energy effectively without affecting normal operation.
4. Common Applications:
• AC and DC power lines.
• Switchgear and relays.
• Consumer electronics (televisions, refrigerators, etc.).
• Renewable energy systems (solar inverters, wind turbines).

KeyTechnical Details

• Nominal Voltage Rating: 680V.
• Maximum Voltage: Approximately 1.5 times the nominal voltage.
• Response Time: <25 nanoseconds (ensures fast clamping action during surges).
• Energy Dissipation: High energy-handling capacity suitable for repetitive surges.
• Temperature Range: Operates effectively in a wide temperature range, typically -40C to +85C.
• Disk Diameter: 14mm for medium-duty surge protection applications.
• UL Certification: Ensures compliance with international safety standards.

Benefits

1. Reliable Overvoltage Protection: Safeguards expensive and sensitive components, improving the lifespan of devices.
2. Compact Design: Small, lightweight, and easily integrated into various circuits.
3. Cost-Effective: Affordable solution for surge and voltage protection.
4. Durability: High energy absorption capability ensures long service life even in harsh environments.
5. Fast Response Time: Quick action minimizes potential damage caused by transient voltage spikes.
6. Ease of Use: Simple two-lead design makes installation straightforward.
