• Available in magnetically shielded or unshielded versions
• Supplied on tape and reel for auto insertion
• Ideal for a variety of DC-DC converter inductor applications
• Lead-free terminations
Measurement Condition
• Inductance is measured with a LCR-meter 4284A (HP)
or equivalent.
• DC resistance is measured by Digital Multimeter TR6871
(Advantest) or equivalent.
• The Rated DC current is that which the inductance value
decreases 10% by the excitation DC current, or which the
temperature rises to 40°C by excitation DC current,
whichever is lower.
Unit: mm
NOTES( * ): D73LF/LC: 3.0 mm max.
D73F/C/CT: 3.5 mm max.
