• Excellent electromagnetic shielding performance for
commercial and industrial applications
• Cost-effective design
• For higher saturation levels
use Series PTHF-VM
• Current rating from 1.69 to 14.5 amps
• Inductance values from 10 µH to 1000 µH
Physical Parameters on Next Page
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.
