Being a newbie hobbyist, I have a hard time finding a certain part or a replacement.
I plan to control a few electroluminescence wires via a microcontroller. The tricky part about these is that they need to be driven by a "higher" voltage (about 60 V to 120 V AC) and frequency (somewhere between 400 Hz and 2 kHz, it seems).
There are several possibilities here but to me the most appealing one is a nice IC with an I²C interface that can drive up to four wires/panels: Maxim MAX14521E.
Getting that isn't the problem, but it requires a tapped inductor for operation. The datasheet mentions the following values: 2.3 μH/115 μH, 1:7 ratio (ISAT = 0.7 A, RS = 1 Ω). I wasn't able to find such a component (or any "tapped inductor" for that matter) in the typical electronic component shops, which undoubtedly is due to me not knowing under what kind of "aliases" such a component may be known, or how to search for it. As far as I've understood, it's a single coil inductor with an additional contact "in between" both ends but I'm not even sure about that.
There's a part specifically made for the MAX14521E which is often used (it's used in Maxim's development kit and also on other boards that I've seen using this chip): the Coilcraft GA3250. It's characteristics are 1.9 μH/112 μH, 1:8 ratio (ISAT = 0.7 A, RS = ?). Unfortunately, it's only available via the manufacturer's homepage with ridiculous shipping fees and takes a whopping 9 weeks delivery.
So I need to find a different part that does the job but I have no idea how to actually search for one. What are the common names for these parts and how do I find them in the large electronic component online shops?
I lack the vocabulary and knowledge to actually do a search for similar components and would like to know which terms and parameters (for the parameterised searches) are going to help me find a replacement.
