Kingbright APECVA3010P3BT phototransistor
These are popular SMT phototransistors. The carrier frequency is filtered out, so run the IR data recording in the no-carrier mode (command register, bit 4 = 1). The output produced by this circuit is "normal" (non-inverted), so set bit 2 of the command register to 0.
This is a photo detector and preamplifier in one package, with good noise filtering. This part is fast enough to preserve the modulation frequency in the output signal. Therefore, set bit 4 of the command register to 0. The output produced by this IC is "normal" (non-inverted), so set bit 2 of the command register to 0.
This is a high-power infrared emitting diode, very popular for IR applications. Notice that a current limiting resistor is not necessary. The diode connects directly to VCC and IR OUTPUT lines of Tibbit #16.
Xantech 282D "designer" emitter and 283D emitter
To connect this emitter, cut the audio connector off the emitter's cable, then connect black-and-white wire to VCC and black write to IR OUTPUT.
