Apakah Anda ingin menggantinya dengan tipe yang ? Apakah Anda kesulitan mencari stok komponen di daerah Anda? Amazon.com: Transistor B778
Jika 2SD998 yang rusak, wajib mengganti juga 2SB778 (dan sebaliknya) dengan persamaan yang sesuai agar suara seimbang. | Parameter | Simbol | Nilai Maksimal |
The B778 (2SB778) is the direct complementary counterpart to the D998. It is a PNP planar silicon power transistor, also intended for audio amplification and power conversion.
adalah informasi krusial bagi teknisi elektronika, terutama saat memperbaiki power amplifier audio atau power supply yang rusak. Transistor KTD998 (NPN) dan KTB778 (PNP) merupakan sepasang transistor final bipolar (BJT) yang bekerja secara komplementer dalam sirkuit push-pull amplifier. Ketika komponen asli sulit ditemukan di toko komponen lokal seperti Shopee Indonesia, Anda harus mencari komponen pengganti dengan spesifikasi elektrik dan konfigurasi pin yang setara agar performa audio tetap jernih dan bertenaga.
