• Excellent electroma gnetic shielding performance
f or commercial and industrial applications
• Cost-effective surf ace mount design
• 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
Notes 1) Rated current is based on a 35°C
temperature rise at an ambient temperature of 90°C .
2) Incremental current is the appro ximate value that
will cause a percentage drop in inductance as
indicated in the table.
