The first two digits (22) are the significant figures, and the third digit (3) is the multiplier (number of zeros). This equals 22,000 picofarads (pF), which easily converts to 22nF or 0.022μF.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: What is the advantage of a \"box\" capacitor over a standard ceramic one?\u003c\/strong\u003e\u003cbr\u003e\nA: Box capacitors are typically made of metallized film housed in a rigid, epoxy-sealed plastic casing. This design gives them superior mechanical durability, excellent resistance to moisture, and \"self-healing\" properties, meaning a small internal short will vaporize and clear itself rather than destroying the component—a crucial feature for 1000V applications.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is this capacitor polarized?\u003c\/strong\u003e\u003cbr\u003e\nA: No, film capacitors are non-polarized. You can install it in your circuit in either direction without worrying about positive or negative orientation.\u003c\/p\u003e\n\n\u003ch5\u003ePackage Includes\u003c\/h5\u003e\n\u003cul\u003e\n\u003cli\u003e1 × 0.022uF (22nF) 1KV Box Film Capacitor\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TOMSON ELECTRONICS","offers":[{"title":"Default Title","offer_id":49488900030702,"sku":"CAP-00005","price":7.0,"currency_code":"INR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2132\/9029\/files\/BOX_CAP_0.022_1KV_KT11.jpg?v=1787596331","url":"https:\/\/www.tomsonelectronics.com\/products\/0-022uf-22nf-1kv-box-film-capacitor","provider":"Tomson Electronics ","version":"1.0","type":"link"}
