GENERAL CHARACTERISTICS
DR1 Power Line Chokes are available in Inductancesranging
from 1 to 560 µh with Saturation Currents ranging from 2.9 to
87 amps DC. High saturation material makes these chokes
ideal for applications needing both high-current values and
small size. Supplied in bulk only.
Notes:
(1) Sa tura tion curr ent lo w er s inductance 5%.
(2) Leads ar e tinned to within 1/16 in. of body .
(3) Coils ar e f inished with UL-VW -1 ra ted sleeving.
