I have a few parts in my Junk Box which I am not sure about. I know the function of some of these (capacitor, resistor, etc), but I am not sure about the type.
I am not as interested in exact values because I can measure them. I am more interested in the qualities and features of each part (ie: poly film capacitor vs tantalum vs electrolytic, etc).
Can any of you Gurus help me out?
Info on each part:
A. About 3/8" thick. No markings other than the colors.
B. No Markings
C. Very round. Marked with: "47-16", "++2" (The 2 is enclosed in a circle)
D. Very thin. Marked with: "K75U", "685Z", "50V"
E. About 1/4" thick. Marked with "WIMA", "0.1", "250-", "F8"
F. Obviously a resistor, but what kind? Markings: "8412", "Dale", "RS-2B", "4.5K 1%", "3W"
G. About 3/8-1/2" thick. Markings: "3,3uF 100 - 5% A D5", "WIMA MKC4-SV21"
H. Very thin. Shiny. Markings: "1979" (perhaps a date code?.. ) "LIBERTY"
I. Square (same thickness and width). Markings: "50", "1826", "9510". On top the value is shown as "3,3K"

A. I've never seen anything like it
B. ditto
C. 0.47uF 16V tantalum capacitor, the + shows polarity
D. 6.8uF 50V capacitor (not sure if it's ceramic or not)
E. 0.1uF 250V capacitor (polyester film?)
F. 4.5k 1% 3W resistor
G. 3.3uF 100V capacitor (polyester?)
H. 1979's equivalent of 2011's dollar
I. 3.3k ohm power resistor ??
A & B look like mylar capacitors but I'd need to find a cap color code chart to guess a value.

A - Philips Polyester Capacitor - 470nF - 630 Volts - 10% Tol.
B - Philips Polyester Capacitor - 22nF - 250 Volts - 10% Tol.
B - Philips Polyester Capacitor - 22nF - 250 Volts - 10% Tol.

E - WIMA polyester pusle cap. 0,1uF, 250V
G - pretty well Marked WIMA cap, check their site for details. I think metalized polyester cap.
I - looks like my Vishay Roederstein 1uF caps.

A and B,
I always knew them as Mullard C280 series, also well known as "liquorice allsorts" or "candy stripe" capacitors.

The followings pics show a variety of capacitors with their tan delta value:

D is an Aerovox gold 50V ceramic cap. 685 is 68x10^5 pf, or 6.8 uf. Z5U is a type of dielectric, a more temperature stable one than CoG. Z is a tolerance, +80-20%. About a $7 cap, if you can find one stocked. I've got 4.7 uf and 10 uf COG's.
