The \"472\" represents the capacitance in picofarads: the first two digits (47) are the base value, and the third digit (2) is the multiplier (number of zeros). So, 47 + 00 = 4700 pF, which translates to 4.7 nF or 0.0047 µF.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Does this capacitor have a specific polarity?\u003c\/strong\u003e\u003cbr\u003e\nA: No. Polyester film capacitors are entirely non-polarized. You can install them into your circuit board in either direction without needing to match positive or negative terminals.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Can I use this 400V DC capacitor directly on a 220V AC mains line?\u003c\/strong\u003e\u003cbr\u003e\nA: It is highly discouraged. While 400V DC is a high rating, AC voltage subjects the dielectric to continuous thermal stress that DC does not. For direct connection across AC mains, you should always use properly rated X-class or Y-class safety capacitors designed specifically to fail safely under AC stress.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 0.0047µF 400V Polyester Film Capacitor (2G472) – PIA Special\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IMPORTED","offers":[{"title":"Default Title","offer_id":48382224990446,"sku":"CAP-00558","price":0.69,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/POLICAP2G472PIASPECIAL.jpg?v=1784876456","url":"https:\/\/www.tomsonelectronics.com\/products\/0-0047-f-400v-polyester-film-capacitor-2g472-pia-special","provider":"Tomson Electronics ","version":"1.0","type":"link"}
