25 pulse mfg. B4005 wideband rf transformers/coil pairs


(25) PULSE MFG. B4005 WIDEBAND RF TRANSFORMERS /
New, old stock (NOS). These small, compact, highly-efficient Pulse B4005 transformers are really great for many RF transformer and inductor applications. They consist of two commonly wound coils of about 175 µH (175 microhenry) each, coil resistances are about 0.5 ohms each. The two 0.1 inch spaced pins on one side are the winding connections for the primary/secondary, and the two 0.1 inch spaced pins on the other side are the winding connections for the secondary/primary. Both the primary and secondary appear to be identical for a 1:1 turns ratio. And of course by cascading them you can get turns ratios of 1:2, 2:1, 1:3, 3:1, etc. I have used these very useful and versatile transformers for countless radio receiver inputs, low-powered radio transmitter outputs, LC oscillators, signal injectors, trigger pulse isolators, and various other transformer and inductor applications. They are also particularly easy to use in prototyping because the leads are 0.3" apart along the width and 0.1" apart along the thickness - making them ideal for solderless prototype breadboards (perfectly spanning the solderless breadboard center gap), for example.
