STR—S6309与STR—S6308具有相同的电路结构,只是前者功率大于后者,它们是STR—S6300系列中应用较广的电源厚膜块。这种新式电源厚膜块较早期的厚膜块(如STR440等)集成度有很大的提高,它主要是将大功率开关管、脉宽调制管、恒流源驱动管及过流保护管等集于一体,使得外围电路简化,可靠性及电路各项性能进一步提高。除夏普某些型号的彩电外,国内流行的康佳、福日、TCL等大屏幕彩电中也有一些使用了该厚膜块。
STR-S6309 and STR-S6308 have the same circuit structure, but the former power is greater than the latter, they are STR-S6300 series of widely used power thick film block. This new power thick film block earlier than the thick film block (such as STR440, etc.) has greatly improved the integration, it is mainly high-power switch, pulse width modulation tube, constant current source driver tube and over-current protection tube Etc. in one, making the peripheral circuit is simplified, the reliability and circuit performance to further improve. In addition to Sharp some models of color TV, the popular domestic Konka, Fukuda, TCL and other large-screen color TV also use some of the thick film block.
