Dobra lista

Malo sam gledao Epcos, ima super kondića.
Recimo http://www.epcos.com/inf/20/50/ds/B2562_.pdf mi se čine vrlo upotrebljivima za cijevna pojačala.
Polypropylen nazivnih napona preko i preko 1000 V i relativno velikih kapaciteta od parsto uF, relativno mali ESR od par mohma.
Cjevoljupci kako vam se čini?

Epcos ima tvornicu u Kutini ali ne znam jeli u njoj proizvode kondenzatore ili nešto drugo.

Pa po karakteristikama izgledaju odlicni. Samo su veliki, a vjerojatno i skupi... Ono prvo im mogu oprostit...

[alfa]

ako tražite polypropylen kondenzatore za malo vece napone reda 300-400v i kapacitete od 25-50 uf obiđite servisere klima uređaja oni uvijek imaju takvih kondenzator na lageru. kakav je polybutenski kondenzator sa MC voskom (tako piše na njemu)?

[joe dalton]

Ako pogledaš u temu 6S19P headamp vidjet ćeš na mojim slikama velike bijele bačvice. To su motorski kondenzatori 400 V (AC) 80 uF i 35 uF polypropylen.
Ima ih u svakom boljem dućanu s elektrodijelovima i rezervnim dijelovima za veš mašine. Ja ih pod normalno koristim u audio pojačalima .

Ovo od Epcosa su monstrumi. Ima ih 1100 V / 1100 uF ili npr. 1320 V / 660 uF.

Pa i meni se čine odlični. A ne čine mi se puno veći od elektrolita za isti kapacitet. Ko što veliš to im se lako može oprostit samo ako su nabavljivi za neku normalnu cijenu.

Znam ih. Ne znam imaju li maloprodaju i da li bi bili voljni prodati 2 ili 4 kondenzatora. To je mala firma i sigurno takve stvari ne drže na skladištu.

Epcos ima tvornicu u Kutini ali ne znam jeli u njoj proizvode kondenzatore ili nešto drugo.

Epcos je vlasnik bivseg SELK kutina, i tamo proizvode razne keramicke materijale, ukljucivo piezoaktuatore i multileayer keramicke kondenzatore, ali koliko znam, maloprodaje tim kanalom nema.
