values of L (OCL) per core material choice for BCP-16 grid chokes.M6 >1000H
Low Ni >2000H
High Ni >3000H
can also be supplied with a small air gap for 1 madc with a yield of 400H
Was originally designed by Freed Transformers as a plate choke in the early to mid fifties.
The conservatively stated L's hold whether the grid choke is a Junior or Senior model.
The approx dcr's are Senior 3800 ohms. Junior 2400 ohms. Remember that in this case dcr
might well be your friend (think damping). Juniors have the advantage of lower winding capacitance.
Pricing is near the same with a slight premium for senior due to more of the expensive core material in it.Recommendation. High nickel works best in low drive (ac volts) applications... where the voltage across it will be
less than five or ten volts. For a typical use between driver tube and output stage of a power amp (where drive level is
say thirty, forty, fifty and up volts) the low nickel or M6 is the better choice.Always comes in channel frames. Steel standard. Brass optional.
Supplied with solder terminals (you supply the hook up wire of your choice).MSL
