    The capacitor labelled '7' in the previous photo comes out to me in measurements at around 4pF, and according to the TDA5100 chip specifications it should be 22pF, where it is labelled nako C7. However, in the schematic above, it is marked as C6 and there is a small error here because on the board C6 and C7 meet at pin 11 of the TDA5100 chip.

    Well, that's exactly it - that's why I couldn't get my head around these components. The datasheet has a different diagram to those given above.
    I'm hoping to get this card working - the four components had no value (rather odd behavior) and no damage was visible on them.
    Thank you VERY much for your quick help!

    Hello, I need the value of the choke (No. 5 in the photo)
    Image of a circuit board with electronic components numbered, with a question regarding the value of the inductor marked as number 5.

Topic summary

The discussion revolves around the rapid battery drain issue of the Renault SCENIC II key card, particularly after a service repair. Users report that the absence of a capacitor in the card may not significantly affect battery consumption, as some have operated without it. However, others have noted that the card's current draw is excessively high, with measurements indicating 300mA at rest and up to 500mA during operation. Participants seek the values of various capacitors and components around the transponder, specifically the TDA5100 chip, to facilitate repairs. There are suggestions to replace damaged components and inquiries about the feasibility of using alternative chips. The conversation highlights the importance of understanding the schematic and component values for effective troubleshooting and repair.
