ERSE 4.5mH 18 AWG I Core Inductor Crossover Coil
ERSE 4.5mH 18 AWG I Core Inductor Crossover Coil is rated 4.0 out of 5 by 3.
Rated 4 out of 5 by from A Good Inexpensive ChokeI needed an inexpensive 4.5 milliHenry choke and this was a good choice. The price of copper has really gone up over the past few years. As usual Parts Express delivers in a timely fashion. I'm happy that they finally got a low cost mailing solution for small orders. But, I still miss those speaker FR charts and actual measured specs.

Rated 5 out of 5 by from Perfect for 1st order low passI bought these for use as low pass filters in a set of 2.5 way monitors that I am building. When connected to an 8 ohm driver these provide 1st order Butterworth attenuation above 280hz. This is just about perfect for my needs as I want my .5 woofer to handle the baffle step correction in the mid-bass frequency range. In my open baffle bench test they seem to be doing exactly what I need them to do.As far as the products themselves, mine looked identical. They are both evenly wound, and nicely wrapped. The plastic frame seems fairly sturdy, and gives you feet and through holes to screw them into the inside of your cabinets. They both have sturdy lead wires that are probably a bit longer than you should need (which is a whole lot nicer than having ones that are too short). Electrically they measured well within specs for DC resistance and very close to each other. Price/Performance ratio is right where I want it to be. These are good performing high value inductors.

Rated 3 out of 5 by from Electrically OK, Mechanically SO-SOI bought two of these.1. Electrically (I measured inductance & DCR) both are within 2% of the stated value.2. Mechanically : one piece is fine, the other has very poor winding technique (turns are bunched up at one end and the overall dimension too large for the inductor feet to sit flat on a mounting surface). If it wasn't so much trouble, I'd return the second piece for a replacement !
