Power Inductors
SERIES
PTHFxxxxR
PTKMxxxxR
PTHF
PTKM
Toroidal Power Chokes
Actual Size
Horizontal or Vertical Mounting
Excellent electromagnetic shielding
Applications Use Series PTHF for high DC saturation
applications; use Series PTKM for low AC core loss
applications.
DC Resistance at 25°C
Rated Idc based upon 40°C maximum rise from 90°C
ambient with 0 Arms
Self Leads Solder coated along entire length
Mounting Toroids can be provided in a vertical or
horizontal mount style. Suffix Part Number with “H” for
horizontal mount.
dI Incremental Current is the value indicated in the table
that will cause an approximate percentage drop in
inductance
Marking DELEVAN and part number.
Example: PTHF50R-121
DELEVAN PTHF50R-121
