مكثف سيراميك ذو طاقة RF عالية

DLC70G مكثف سيراميك عالي الطاقة
تتميز المكثفات الخزفية ذات طاقة الترددات اللاسلكية العالية بانخفاض ESR، وخسارة منخفضة، وأداء فائق التردد العالي، مع مقاومة منخفضة، وتوليد حرارة منخفض، ومقاومة تيار عالية. إنها توفر خصائص درجة حرارة ثابتة ومقاومة موثوقة للجهد وعزل جيد. إنها مدمجة ومتينة في الهيكل، وتوفر اهتزازًا قويًا وقدرة على التكيف البيئي، مما يقلل بشكل فعال من التداخل عالي التردد وفقدان الإشارة. مثالية للاتصالات اللاسلكية ومعدات الميكروويف وأنظمة الطاقة عالية التردد، فهي تضمن تشغيل الدائرة بكفاءة وثبات.
