Varistor SMD 1812 Energi Sedang hingga Tinggi | Perlindungan Lonjakan untuk Sistem Daya & Industri
Serangkaian Varistor Oksida Logam 1812 SMD adalah komponen pelindung tegangan berlebih yang dipasang permukaan yang dirancang untuk penyerapan energi lebih tinggi dan ketahanan arus lonjakan. Dengan paket ukuran 4,6 × 3,2 mm, mereka melampaui perangkat 1210 dalam kapasitas lonjakan dan rentang tegangan, menjadikannya ideal untuk jalur daya industri, simpul komunikasi grid, dan sistem listrik kendaraan. Dengan respons sub-nanodetik dan stabilitas yang sangat baik, mereka mendukung desain PCB SMT padat.
Serangkaian SMD 1812 digunakan secara luas dalam perlindungan lonjakan untuk:
