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.

Repeat for finding a known station, but instead adjust the left brass screw — the higher one. The best rule of thumb when assembling circuit boards is to start with the datasheeg height components and progress to the tallest ones. The other two battery terminals form the positive and negative.
Frank McCaffery Dec 20 Assembled without too much trouble. The educational value, however, is a little limited without explanations. I have also had issues in getting the stations in the right place on the dial. catasheet
Click for more about me! March 23, at Note the orientation, unbend the pins, insert and solder away.
Once it is soldered, the speaker can be glued into the front casing with hot melt glue around the edge or superglue if unavailable. Start alignment with the FM band. Datashfet two ensures that you have some spares in case things do go wrong … This post will be a little review of the kit, along with tips and hints especially for English speaking constructors.
Otherwise, the IC may not be soldered in the right orientation, or the switch may have been damaged. At this stage, we are ready to make the final connections and assemble the unit.
Turn fatasheet 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. It also gives you the best access datasheey soldering SMT parts. As mentioned, the instructions were all in Chinese.
The values can either be read or checked with a meter. Try not to bend the leads too severely, as cracking the other protective coating can have detrimental effects on capacitor stability or performance. I have found the AM section to be very un-selective.
For tuning drilled the back for access to adj screws on tuning capacitor. Do the soldering with the antenna on the benchso not to melt the casing, and ensure adequate heat. Conclusion After enjoying repairing a few AM radio kits, I embarked on a challenge to build a cheap Chinese dual-band radio kit.
Having some kit-building experience helps you avoid basic mistakes like this. This really is a kit that looks almost store bought! Once that is dialled in, the unit has been tuned and the radio should now be somewhat functional.
Continuing on, the board is completed with the cd9808cb of resistors. For this, stick the wire through the slot in the rear of the casing, and the screw hole end of the antenna cx9088cb the slot.
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. The next step was to mount the hardware — the headphone jack, the variable capacitor, the volume switch and the band switch. Just another way engineering solves the day!

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. By now, most of the remaining components are resistors or capacitors.
Insert your two AA batteries of choice, and you can start listening to radio right away. September 8, at 1:
