CDCB ETC datasheet pdf data sheet FREE Datasheets (data sheet) search for integrated circuits (ic), semiconductors and other electronic components. The schematic as listed is shown above. The CD is responsible for FM reception, with the only datasheet I could find being in Chinese. Data Sheet INTERNATIONAL RECTIFIER IOR. T 10TQ SERIES. 10 Amp Schottky Rectifiers. Major Ratings and Characteristics.

Next, obtain the larger tuning dial and align the indentation. February 5, at 7: Start alignment with the FM band. I wonder if adding some holes in the back of the case would help. November 24, at 8: Secure the rear of the case to the front using three long tapping screws on the exposed holes, and a short tapping screw on the hole inside the battery compartment.

If I was doing this again, as I did for my second kit, I would populate the resistors before the capacitors mainly because cd908c8b clearance to get resistors flush on the board is limited once the capacitors are installed.
Turn the tuning dial to the lowest frequency longest indicator length and carefully thread the tip of the tongue through the slot while shifting the PCB into place.
Maybe one radio station at the most. November 10, at 3: It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. Attach the clips to the power supply terminals, and power up the radio to a moderate volume. Filtering is achieved with the external components — mainly R-C filters.
It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. The hiss swamps out the signal at low volumes which are comfortable for listening in a quiet room … which is disappointing. Instead, you will have to solder the yellow wire to the arm next to the screw hole, making sure the solder is low profile not to interfere with fitting the antenna through the slot.

The FM antenna also needs to have a wire connected to it. February 5, at 5: The paper substrate also likes to discolour with such heating and smoke.
I would be very grateful if someone could help me.
cd90888cb First, slide the battery terminals into place — positive is the top terminal on the front case, negative is the lower terminal.
Massage it over the end of the rod, and glue into place optional. Sidecutters to cut off component legs. To adjust the FM alignment, you need to use a flat blade screwdriver and adjust the right brass screw on the rear of the variable eatasheet i. Align the switch and use one of the two identical machine screws to fasten. The other two battery terminals form the positive and negative. Note the orientation, unbend the pins, insert and solder away. Two AA batteries to power the receiver.
Small flat-blade screwdriver to perform the variable-cap tuning procedure. Because there were more capacitors, I decided to tackle them first. Take note of the orientation, insert, bend leads, solder and clip leads until all the electrolytics are mounted.
You can remove the self-adhesive backing from the front window and apply it to the front of the casing, checking the orientation. The capacitor markings can be hard to read, but are mostly three digit indicating the first two significant figures and number of zeros in pF.
Magnifying datadheet and light to read small component values and markings also optional. In the case of this kit, this specifically includes:. Datashheet 17, at 5: This really is a kit that looks almost store bought! I found the top of the FM band hard to reach, but not impossible with a combination of spreading the coils and adjusting the offset trim on the variable capacitor itself.
Luckily for everyone, the board also has very good silkscreening to judge by the listing. Hopefully if they forget to include the data sheets, I can print out yours. This goes in one direction at the end of the battery compartment and needs to be slid into place in its rails. But at least they did provide the jack. Rather unimpressively, each kit comes in a bubble wrap package. September 12, at 3: Then secure this with the other identical machine screw.
I agree about the SMD Hot air re-flowing.
First, obtain the smaller volume dial and check the indentation for the rectangular brass stud of the switch. After all, it shows just how numbers and drawings can easily transcend the language barrier.

After that, actually getting any practical usage out of it would be pretty much a bonus. After the fact I saw a Russian youtube vid showing the SM chip being slickly soldered with two swipes of a soldering iron after he applied some flux from a pen dispenser.
Check the orientation of the plastic holder and the PCB slot, and glue it into place so it holds the ferrite rod parallel to the PCB.
