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.
