Vertical Toroidal Power Chokes
• 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

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.
