I have a big problem from telling what kind of resistor material types and capacitor material types


HOw do you tell if a resistor is a Carbon Film resistors or Metal Film resistors?
I can't tell any difference at all from looking at them on different PCB devices
so its hard for me to order which kinds, how would i tell please?

Which brand names back in the days did Carbon Composition Resistors come from ? allen bradly and who else please

The allen brady carbon composition resistors are easiy to tell because they always have a BROWN body color

But i don't know who makes those carbon composition resistor that are TAN cream body color or a redish body color

Ceramic capacitors- look like a brownish/orangeish circle

Polyester film cap- looks like a small yellow square box

Polystyrene- looks like a coil inside always?

Polypropylene- ?

Silver Mica- look like a Redish square cap with a "dip" in the middle of it

Mylar capacitors- ?

Polycarbonate capacitors- ?

Capacitors with color codes? they are Polyester capacitors right?

Metalized Polyester film cap- look like a white square box

Tantalum caps- look like a "tire drop" brown color

Polyester = Mylar film

Whats the difference between Polyester film VS Mylar film?

Polystyrene is easily melted-

Polystyrene capacitors can be damaged by heat when soldering (it melts the polystyrene!) so you should use a heat sink (such as a crocodile clip). Clip the heat sink to the lead between the capacitor and the joint.

What type of capacitor material are these orange drops?

What type of capcitor material are these Mustard capacitors?

They look like Polyester film cap to me

Mullard Tropical Fish capacitors
"tropical fish" are polyester film capacitors

So what's the question?????????????

If you have a question ask it but do not ask a question and supply your own answer in the same post. It confuses people!

My question is i Can't NOT tell the differences between these types of capacitors or resistor material types

I have a problem with the bill of materials , so how can i tell fromt he LOOKS or any tips how to tell the differences of these resistors or capacitors?

If you want to buy very old expensive 600V orange drop capacitors with a horrible plus and minus 20% (M) tolerance then go ahead and buy them before they are all gone.

The same for old carbon composition resistors.

From above link:
"Replicas of the authentic Film-to-Foil Alu/PE design of the 60s Mullard/Philips capacitors as used in famous british Amps of the 60s till mid 70s."

-- looks like a metal film type with Polyethylene (PE) plastic.

So the Orange drops are Polypropylene Film Capacitors?

The Mustard caps are Polyethylene ?

Whats the difference between the orange drops VS Mustard caps is they both are Polyethylene caps?

Orange Drops are Polypropylene Film Capacitor not Metalized Polypropylene but the FILM

There is 4 types of Polyproylene or Polyester
1.) FOIL
2.) FILM
3.) Metalized
4.) Mylar?

Orange Drops either come Polypropylene or Polyester they have both kinds



Bumblebee capacitors? What type of material are these? they have color codes on them too

I think the Bumblebee capacitors are Paper-In-Oil ?

Google is your friend. Look up tutorials on capacitor types and construction.

There is 4 types of Polyproylene or Polyester
1.) FOIL
2.) FILM
3.) Metalized
4.) Mylar?
Nope

Bumblebee capacitors? What type of material are these? they have color codes on them too
That's why they are "Bumblebee"
