{"product_id":"bc-239-npn","title":"Bc 239 NPN","description":"\u003cp\u003eThe BC 239 NPN transistor is a reliable silicon semiconductor designed for amplification and switching in small-signal circuits. Its combination of moderate voltage and current ratings, high gain, and good frequency response makes it suitable for audio, communication and general-purpose electronic applications where low noise and stable performance are required.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollector-Emitter Voltage:\u003c\/strong\u003e up to 40 V.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCollector Current:\u003c\/strong\u003e up to 100 mA.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCurrent Gain (hFE):\u003c\/strong\u003e typically in the 100–300 range.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransition Frequency (fT):\u003c\/strong\u003e effective operation up to 100 MHz.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Type:\u003c\/strong\u003e TO-18 metal can for enhanced thermal dissipation and durability.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eConstructed with silicon technology, the BC 239 delivers stable electrical characteristics across varying temperatures and operating conditions. Its elevated gain and frequency performance support precise amplification, while the metal TO-18 casing improves heat dissipation and mechanical robustness compared with plastic-packaged alternatives. Low intrinsic noise and consistent behavior make this transistor a preferred choice for audio preamplifiers, small-signal stages and other circuits where fidelity and repeatable performance matter.\u003c\/p\u003e","brand":"Electronic Service Center","offers":[{"title":"Default Title","offer_id":42556914892983,"sku":"","price":2.0,"currency_code":"LYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/4010\/0279\/files\/IMG-20240404-WA0016_5dd6be2e-0bcf-4062-ad27-f58ebf9c5c4f.jpg?v=1784939433","url":"https:\/\/esclibya.com\/ar-ly\/products\/bc-239-npn","provider":"Electronic Service Center","version":"1.0","type":"link"}
