14D221K Metal Oxide Varistor 220V 14mm Radial ±10 Percent 4.5KA Surge Protection

The 14D221K Metal Oxide Varistor (MOV) is engineered for effective suppression of overvoltage transients in AC and DC circuits. With a varistor voltage of 220V and a maximum continuous operating voltage of 140VAC, this component is commonly used for AC power line protection, switching circuits, power adapters, and home appliances. The radial leaded 14mm disc design provides compact and reliable mounting on PCBs. It is capable of withstanding surge currents up to 4.5KA and has a typical clamping voltage of 360V, ensuring protection for downstream circuitry.

Key Features:

• 220V varistor voltage with ±10% tolerance for stable clamping behavior
• Supports continuous operating voltage of 140VAC / 180VDC
• Handles surge currents up to 4.5KA (8/20μs waveform)
• 14mm disc radial type ideal for compact PCB mounting
• Fast response time under 25ns for immediate transient suppression
• RoHS compliant and UL certified for high-reliability applications

Additional Specifications:

• Capacitance: 450 pF to 650 pF
• Voltage Rating: 140V AC / 180V DC
