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
