但应不全是煲机的功劳
原来我的退耦小电容全用WIMA的1uF的。今天发现接在TL431调整端的0.01uF好像不是普通退耦用(不知对吗?) [em12]所以复原为0.01uF了[em11][em11][em11]
就是下图红线画的五个<img src="attachments/dvbbs/2005-2/2005225153837361.gif" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-2/2005225153837361.gif\');}" onmousewheel="return imgzoom(this);" alt="" /> |
