# MOV-14D471K (Component) ## Description VARISTOR 470V 4.5kA P=7.5mm The MOV-14D471K is a 14 mm radial leaded metal-oxide varistor designed to protect electronic circuits from sudden voltage spikes such as lightning surges, switching transients, and power-line disturbances. It works by clamping high voltage surges and safely absorbing surge energy, preventing damage to sensitive components downstream. It is commonly placed across L–N (line to neutral) in AC input stages of power supplies and appliances. ⚙️ Key Features Varistor voltage: ~470 V (at 1 mA reference current) Maximum AC operating voltage: 300 VAC Maximum DC voltage: 385 VDC Surge current capability: up to 4.5 kA (8/20 µs pulse) Energy absorption rating: ~125 J Clamping voltage: ~775 V (at rated surge current) Capacitance: ~430 pF Response time: very fast (< nanoseconds range, typical MOV behavior) Operating temperature: -40°C to +85°C (typical range) ## Component Details - **Owner:** lcsc - **Created:** 11/2/2024 - **Last Updated:** 5/28/2026 - **Visibility:** Public - **License:** https://creativecommons.org/licenses/by/4.0/ - **JLCPCB Part Class:** Extended Part - **Part Type:** Varistors - **LCSC Part Number:** C1527439 - **Manufacturer Part Number:** MOV-14D471K - **Package or Case Code:** RES-TH_L16.5-W5.4-P7.50-D0.8-S2.80 - **Manufacturer Name:** BOURNS - **Datasheet URL:** https://www.lcsc.com/datasheet/C1527439.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNRTlhaX1BST1NcVDsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Used in:** 208 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
