Most post-war European thermionic valve (vacuum tube) manufacturers have used the Mullard–Philips tube designation naming scheme. Special quality variants may have the letter "S" appended, or the device description letters may be swapped with the numerals (e.g. an E82CC is a special quality version of an ECC82)
Mullard initially handled semiconductor naming by using the "O" heater code (shifting "Cold Cathode" to a code of "Z"). The second letter broadly indicated the type of device, roughly following the tube designation, without indicating the semiconductor material: A low-power semiconductor diode, e.g. OA7

Since the repetition of the 36 kHz carrier is 27.778 μs and the duty factor is 25 %, the carrier pulse duration is 6.944 μs. Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778 μs = 1.778 ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889 ms to transmit.
