For this brand of ceramics (X7R) is practically no dependence of characteristics of thecapacitor's size !
Just an example of PCB is given for this size.
Hi, Any documentation on TVM502T is necessary - part list, schematic, mechanic diagram, service manual, datasheet on IC and e.t.
The drive is used in THOMSON DVD430T.
Symptoms - the disk is not defined ("No Disk"), the spindle does not rotate.
Thanks.
