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.

The other two battery terminals form the positive and negative. 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.
As mentioned, the instructions were all in Chinese. So, I rummaged on eBay looking for radio kits, and surprisingly, there were quite a few! Use the slightly different machine screw to secure the antenna to the rear casing. For speaker used twisted pair.
Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. It seems to have a lacquer finish to stop the pads from oxidising, but is not otherwise tinned nor plated. After all, it shows just how numbers and drawings can easily transcend the language barrier. I must have used the wrong screw for the antenna as it became loose and I ended up replacing it with a self tap of slightly larger size.

Some of the hardware has a habit of shifting in place during soldering. Continuing on, the board is completed with the population of resistors.
Start by securing the PCB to the front of the case using a short tapping screw on the stud in-between the volume and tuning dials. We start by first emptying all components into a plastic bowl so they can be sorted through. Insert the ferrite rod into the end to check the fit, then glue to the rod into the holder.

First, slide the battery terminals into place — positive is the top terminal on the front case, negative is the lower terminal.
February 5, at 7: January 17, at 5: Next, solder the speaker wires with both yellow datashfet going to one SP terminal respectively. Desoldering braid optional to fix mistakes. Part of the cause seems to be the jack itself being slightly larger than the hole in the rear plastic cover — reaming out the hole slightly using a large Philips head screwdriver seems to do the trick.
Datashert this stage, I decided to mount the electrolytic capacitors, since there were only a dxtasheet of them and their values are easy to read. Sometimes, because of production reasons in both my kits the capacitors can become unmarked for some reason. The next step is to align the AM band. 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.
April 25, at The best rule of thumb when assembling circuit boards is to start with the lowest height components and dtasheet to the tallest ones.
Luckily for everyone, the board also has very good silkscreening to judge by the listing. February 5, at 5: Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.
Next thing was to solder a pair of yellow wires to the positive and negative datashdet the speaker. I would be very dattasheet if someone could help me. I have also had issues in getting the stations in the right place on the dial.
In the case of this kit, this specifically includes:. Do not touch the antenna or you may be burnt! Now, the screws need to datasgeet sorted and the dials installed. However, you might encounter some critical issues here. The kit itself is not entirely trouble-free, and you do need to be suitably equipped to build it.
I suppose it just depends where you are relative to the transmitter, and to some extent, maybe the quality of the chips or construction. September 8, at 1: Note the temptation to use hot-air reflow techniques. The paper substrate also likes to discolour with such heating and smoke. The FM antenna also needs datahseet have a wire connected to it.
Repeat for the UTC as well.
Everything is in Chinese. Take care with cd9088vb ceramic disc capacitors not to lose them as some are extremely small. Massage it over the end of the rod, and glue into place optional.
