Reichelt Bauteile NEWS *Fakes & Fehler*

Postby nrgrecording » Sun Feb 25, 2007 1:17 pm

Wie den meisten bestimmt schon selber aufgefallen ist gibts bei Reichelt schonmal gerne "Überaschungseier" in Sachen Bauteile. Bedingt durch den niedriegen Preis den wie ja nur bezahlen wollen... muss die Angie (Angelika Reichelt) ja da kaufen wo es am billigsten ist. Unter den Endstufenbastlern fällt so etwas natürlich als erstes auf - wenn Die Leistungstransistoren schon halber Leistung mit der weißen Fahne winken.
Mir kam dann die Idee evtl. einen Beitrag zu machen wo jede seine Erfahrung in Sachen Reichelt Bauteile posten kann. Ich fange mal an:

Tantal Kondensatoren:
Bei den Tantalkondensatoren ist ein schwarzer Balken aufgedruckt. Leider weist dieser auf + oder - hin - also beides :D mal so - mal so... :evil:
Ich hänge die Kondensatoren dann eben mal an die maximale Betriebsspannung in der Polarität die ich mir vorher ausgedacht habe - wenns dann raucht - ists genau anders herum.

Weller Lötspitzen:
Komischerweise halten die Lötspitzen für die Weller WECP's nicht lange. Allerdings steht auch nicht dabei das es original Weller Lötspitzen sind. So halten z.B. Lötspitzen von Schuricht, Conrad... locker 10x so lange

Leistungstransistoren:
Diese haben gerne mal anstatt einer großen Transistorfläche - zwei kleine Flächen unter dem Gehäuse. Bei 3055 die mit höherer Leistung betrieben werden sollen sollte man vielleicht ersteinmal das Gehäuse aufknacken um nachzuschauen ob da auch was drin is. Bilder dazu gibts auch im Netz per google.

Spannungsregler:
Neben dem bekannten Problem bei symmetrisch aufgebauten Netzteilen das eine Spannung erst nach mehrmaligem einschalten auf den richtigen Wert kommt (was evtl. auch Herstellerabhängig ist) sind neuerdings Spannungsregler mit falschen Aufdruck in Umlauf. Da haben Regler die "7815" aufgedruckt haben spontan -18V - ein andere aus gleicher Lieferung -24V, ein 7812 hat plötzlich +9V. (danke für die Info, Karsten!)

Wima Kondensatoren
Seit letztem Jahr kommen die "Wima's" plötzlich ohne Aufdruck daher. Vermutlich ein Zeichen das sich die FakeBauteieleHersteller entweder den Aufdruck sparen? :D So viel ich weis gibt es aber keine original Wima's ohne Aufdruck.

Sortierung
Wenn man mit dem Basteln gerade erst anfängt bestellt am anfangs öfter auch die Widerstände mehr oder weniger einzeln. Da kommt es schonmal vor das der falsche Widerstand in das Tütchen rutscht. Deswegen sollte man - gerade als Einsteiger - alle Widerstände nachmessen. Ich mache das sogar heute noch so. Dauert nur unwesentlich länger - hilft aber im Zweifelsfall Zeit zu sparen.

Hab ich schon gewundert warum meine Lötspitze sich so schnell in Luft auflöst. :roll:
