This year we have extended our range of chokes and inductors, and therefore restructured our web page where the chokes are presented.

The chokes are separated into four different categories based on operating current. As there is no fundamental difference between chokes intended for power supplies applications or for anode choke applications, anode chokes can very well be used in power supplies, and vice versa. The “Capacity (I*L)” column indicates which current/inductance combination you can expect from a choke. For instance, I*L-value for LL1638 in series connection is 1.5Vs which indicates that the operating current for LL1638/10H is 0.15A (as 10H * 0.15A is 1.5Vs).
