主要是考虑避免出现因上电不同步导致器件逻辑锁死

DANIELYANG 发表于 2005-2-23 23:19

有这么麻烦么

数模独立稳压供电就会导致死锁？一般的稳压也不至于有0.4伏误差这么大吧？

文招 发表于 2005-2-23 21:34

呵呵

应该还有其它作用的吧

谢MM了
可惜没什么关于二极管的说明

哈哈，上当受骗者增加多1个了！！！

关于二极管的说明！有！马上发！

看：

是这2个吧？？

又搞错了。。。

好象没搞错。。哈哈。。

请问鬼版图在哪？

下方的图,楠亮平在第二台解码器的CS8412中也是这样用(两只二极管)...你们不妨找找看

我找了很久，没见。可否给个练接

swuzzy 发表于 2005-2-22 23:16

我的数字部分用了几个WIMA的MKS4

感觉还不错

teco 发表于 2005-2-22 16:10

上不来图?

teco 发表于 2005-2-22 16:08

这个电阻做I/V如何?

有人知道它的来头么?

7r093 发表于 2005-2-22 13:26

LP扶一下我，我快撑不住了。

早知就不进来了，可手有不听使唤，呼吸困难啊！好家伙！

小鬼头 发表于 2005-2-22 07:47

wongkm33兄

听说WIMA的FKP还不错

teco 发表于 2005-2-22 03:56

像个前级

swuzzy的蛋放大部分用料很正点

wongkm33 发表于 2005-2-21 20:54

这种电容有耐压达1250V，常用在水平电路上。

以下是引用swuzzy在2005-2-21 17:53:00的发言：
最下面的好像是金属化纸界电容，这东西不错；上面几个应该是分频器里的东东吧，不是很好的。


下面是一些耐压在1000V以上的垃圾。

图中左边的是欧洲电容(大部分是WIMA)，右边是日本的。相信在在一些高压胆机用的着。

我的接法如上图，是闭锁了没声音。
后来有个大虾教我如下图接。但我没试，因为我的稳压拆除了，数模混用一组。<img src="attachments/dvbbs/2005-2/2005220163134311.jpg" 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/2005-2/2005220163134311.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

第二图的只是普通货色,不是聚苯乙稀...聚苯乙稀电容是软脚的,因为这种介质不耐热

重武器真是眼馋啊～

老大们分我几个吧

文招 发表于 2005-2-21 17:37

55555还是不看的好，害怕中毒

文招 发表于 2005-2-21 17:34

那私弊的电解和我的一样啊

只是我的烂像头表达不出罢了

swuzzy 发表于 2005-2-21 17:31

传几个1541装机的图，文招兄给看看，东西一般：

<img src="attachments/dvbbs/2005-2/2005221172558574.jpg" 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/2005-2/2005221172558574.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
<img src="attachments/dvbbs/2005-2/2005221172619884.jpg" 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/2005-2/2005221172619884.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这是输出并联的V-Q，下面的黑色大S是并联在高压电源上的

<img src="attachments/dvbbs/2005-2/2005221172742350.jpg" 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/2005-2/2005221172742350.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这是私弊的电解，高压主滤波
<img src="attachments/dvbbs/2005-2/2005221172842623.jpg" 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/2005-2/2005221172842623.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这个油浸也是高压滤波，接在阳极电阻焊点上
<img src="attachments/dvbbs/2005-2/2005221173039505.jpg" 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/2005-2/2005221173039505.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
