May I know what are the differences between these red and green wima? Thanks RDL2004 I think all Wima box-style caps are red. That's why I use them, they look good on the pc board :) The green ones are probably just another brand, maybe Roderstein? Wima products - Rick SY My Wima FKP-1 are blue. FKC-2 are yellow. And I have some green ones, but I'm not sure of the series. These are all out of an assortment pack provided by Wima's local rep. ACD The FKP2 Polyprop series are green ;) cowanrg they all have a different sound. the red ones sound very warm. they have a very passionate sound to them. the green ones give an organic sound to the music. the blue ones will give you liquid midrange and airy highs. the yellow ones tend to make your tweeters beam. Spirtos WIMA FKP2 (foil polypropylene) are green, range 100pF - 2,2nF and voltage 63V and 100V,Also tolerance 5%, 2,5%, 1%. FKP1, red, same values as above but voltage range up to 1000V. WIMA MKS 02, MKS 2, MKS04, MKS4 (metallized polyester) are red, different dimensions and range between 100nF - 10uF . MKS4 voltage 100V - 1000V. MKP4 and MKP10 (metallized polypropylene) value range 100n - 10uF and voltage 160V - 1000V. There are also some other general purpose types like : FKS, FKC with red, yellow, green colours. That's what I have used so far. Generally it is difficult to find all the ranges and types in one distributor, some types is almost impossible to find them. So far I have not achieved it. Regards Spiros djQUAN that's funny....... I have a few 3.3uF 63V green wimas. Nordic I think the green ones are slightly bette (more expensive at least) but I love the 10nf red ones for decoupling opamps... it realy cleans up. oncle_tom Fort their newest production Wima uses only red boxes. Older FKP2 are green, FKC yellow, FKP1/3 blue... Peter phase_accurate This German manufacturer (Silbersand) seems to use both red and green types: http://www.johannes-krings.com/uplo...s/1340/DSC_0037 Regards Charles phase_accurate My favourite distributor carries the green ones, but only with 10% tolerance unfortunately: http://www.distrelec.com/ishopWebFr...eries/is/1.html I don't dare to ask how much they will cost with 2.5 % tolerance since the 10 % ones are already quite expensive. They seem to be quite good however. They have a low-inductance foil-construction and low dielectric absorbtion: http://www.distrelec.com/ishopWebFr...eries/is/1.html Regards Charles RDL2004 Well, if you had followed the link I gave and checked the data for each and every type of box-style capacitor from 2.5mm to 7.5mm, as I did, you would see that they are now all red. The ones you guys have or can find must be old stock, or maybe the red ones are all they export to the US? However, if you look here you will find green ones :)
