SERIES
• Excellent electromagnetic shielding performance for
commercial and industrial applications
• For higher saturation levels use Series PTHF-SM
• Current rating from 0.92 to 7.36 amps
• Inductance values from 10 µH to 330 µH
Marking API; ether PTHF or PTKM; remainder of part
number.
Example: PTKM50R-50SM
API
PTHF
50R-50SM
Notes 1) Rated current is based on a 35°C temperature
rise at an ambient temperature of 90°C. 2) Incremental
current is the approximate value that will cause a
percentage drop in inductance as indicated in the table.
