{"product_id":"coil-inductors","title":"Coil Inductors ملفات","description":"\u003cp\u003eCoil Inductors (ملفات) are passive electrical components that store energy in a magnetic field when electrical current passes through their windings. They are fundamental building blocks in a wide range of electronic circuits, providing impedance to alternating current, filtering noise, smoothing power supply outputs, and forming tuned circuits in radio-frequency applications. Coil inductors are available in many shapes and sizes, including air-core coils, ferrite-core coils, toroidal coils, and bobbin-wound types, each chosen for specific electrical and mechanical characteristics.\u003c\/p\u003e\u003cp\u003eTypical considerations when selecting a coil inductor include inductance value (measured in henries), current rating, DC resistance (DCR), quality factor (Q), self-resonant frequency (SRF), core material, and thermal performance. Air-core coils offer low loss and predictable inductance at higher frequencies, while ferrite-core and powdered-iron cores provide higher inductance in a compact footprint and improved magnetic coupling for power and RF applications. Toroidal geometries reduce electromagnetic interference (EMI) and stray flux, making them suitable for sensitive or space-constrained designs.\u003c\/p\u003e\u003cp\u003eCoil inductors are commonly used in power supplies (for buck, boost, and other converters), EMI\/RFI filters, RF matching networks, oscillators, and impedance matching circuits. Proper selection and layout—including consideration of shielding, mounting orientation, and thermal dissipation—help ensure reliable performance and long-term stability. When integrating coil inductors into a design, review the manufacturer’s datasheet for rated current, saturation characteristics, and recommended operating conditions to match the inductor to the circuit’s electrical and environmental requirements.\u003c\/p\u003e","brand":"Electronic Service Center","offers":[{"title":"12.5 uH","offer_id":45128727658679,"sku":null,"price":0.5,"currency_code":"LYD","in_stock":true},{"title":"13 uH","offer_id":45128727691447,"sku":null,"price":0.5,"currency_code":"LYD","in_stock":true},{"title":"16.2 uH","offer_id":45128727724215,"sku":null,"price":0.5,"currency_code":"LYD","in_stock":true},{"title":"47 uH","offer_id":45128727756983,"sku":null,"price":0.5,"currency_code":"LYD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0639\/4010\/0279\/files\/IMG-5272.png?v=1753880730","url":"https:\/\/esclibya.com\/en-ly\/products\/coil-inductors","provider":"Electronic Service Center","version":"1.0","type":"link"}
