Title: QRV09 Capacitor wrong size
Post by: jhmvanbeek on February 25, 2014, 07:16:02 PM
Hi there,

I bought recently the QRV09 headphone amplifier.
I used your part list to order the components at Farnell.
I was nearly finished, just had to soldeer capacitor C1 and C8 100nF/50V and they wont just fit (to small). :-D
Is there another part number change for it.

Best Regards

Hans

1414664 is the part number and is an 0805 part. What kind of part did you get?

According to the file BOM-qrv09r0.xls component C1 and C8 has the description 100 nF, 50 VDC, 10%, metallized polyphenylene sulphide (PPS), 2220 and has Farnell number 1657962.

Sorry, looked at the wrong part. Farnell doesn't have the exact part but if it's smaller than expected you can fit them. It worse the other way around. Maybe I should check once again if Farnell maybe has the right size.

1855059 Is a better substitute if we talk about size.
