Glaze High Power Ceramic Tube Resistors (BHR)
被釉功率瓷管電阻器

Features
特點(diǎn)

1. Surface glazed, won’t be easily polluted or eroded by chemistry gas, high insulating capacity, can resist humidity and heat well, can be used in the atrocious environment.

電阻表面被釉，污染，耐化學(xué)氣體侵蝕、緣度高，耐濕耐溫，能在惡劣環(huán)境下使用。

1. Good overload and heat durability capacity, the useful time is longer than the others.

高負(fù)荷，，使用壽命相對(duì)其他產(chǎn)品較長(zhǎng)。
3.  Resistance tolerance范圍: &plun;5%, &plun;10%.
