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.

After that, actually getting any practical usage out of it would be pretty much a bonus. Superglue is not preferable because it cracks when the case is flexed, but should still work somewhat adequately. Then secure this with the other identical machine screw. We start by first emptying all components into a plastic bowl so they can be sorted through. Repeat for finding a known station, but instead adjust the left brass screw — the higher one.
Just another way engineering solves the day! Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance.
Note the temptation to use hot-air reflow techniques. Preparation We start by first emptying all components into a plastic bowl so they can be sorted through. Use the slightly different machine screw to secure the antenna to the rear casing.
November 10, at 3: It is used to drive the headphone jack which disconnects the internal speaker once a headphone plug is plugged in. Hi, I have had made it 3 times, and the last was today.
Lead the yellow wire to the ANT terminal and tack solder. Proudly powered by WordPress. Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable.
At this stage, we are ready to make the final connections and assemble the unit.
Continuing on, the board cd90088cb completed with the population of resistors. The final connection is the FM antenna connection. Now, the screws need to be sorted and the dials installed.

Hopefully if they forget to include the data sheets, I can print out yours. Small flat-blade screwdriver to perform the variable-cap tuning procedure.
Trouble was already spotted when a loose screw was seen rattling inside the bubble wrap — the components have broken loose and the only thing preventing them from going everywhere was a thin and somewhat torn bubble wrap. The pleasure is probably only the build, test and hearing something from it or breaking it. Once roughly in place, you can take the AM-FM mode switch, deburr the plastic and push it through the exterior datasueet over the datasheett.
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. Filtering is achieved with the external components — mainly R-C filters.
Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit. The other comment about dztasheet solder paste and running the tip along the pins is one i agree with also, even if some clean up is required afterwards.
Next, solder the speaker wires with both yellow wires going to one SP terminal respectively. Get good reception aroun Mhz with correct pointer position. Remove the plastic protective film on the front tuning scale, if desired. Everything is in Chinese. Another radio that is in tune to verify received stations also recommended, but not absolutely necessary.
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. The next step is to align the AM band. In the case of this kit, this specifically includes: A capacitor is hence a 10 pF capacitor, or 0. September 8, at 1: I enjoyed a datasyeet this kit.

February 5, at 7: The hiss swamps out the signal at low datashert which are comfortable for listening in a quiet room … which is disappointing. The schematic as listed is shown above. For this, stick the wire through the slot in the rear of the casing, and the screw hole end of the antenna through the slot. 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. I did have problems with the jack but left it misaligned.
April 25, at But at least they did provide the jack.
