Being a newbie hobbyist, I have a hard time finding a certain part or how to find 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 "higher" voltage (about 60V to 120V AC) and frequency (somewhere between 400Hz and 2kHz, 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: 2.3μH/115μH, 1:7 ratio (ISAT = 0.7A, RS = 1Ω). I wasn't able to find such a component (or any "tapped inductor" for that matter) on the typical electronic component shops, which undoubtedly is due to me not knowing what kind of "aliases" such a component may be known as 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 1.9μH/112μH, 1:8 ratio (ISAT = 0.7A, 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 component and would like to know which terms and parameters (for the parameterised searches) are going to help me find a replacement.
