Description
The TOKO D412C Series is an extremely low profile surface mount
fixed inductor with a maximum height of 1.2mm. The product is
magnetically shielded and designed for space constrained DC-DC
converter applications in portable platforms including wireless
handsets, PDA's, and consumer electronics.
Features
4.6mm x 4.6mm footprint (±0.2mm)
1.2mm maximum height
Magnetically shielded
Reflow solderable
Packaged on 2000 piece reels
Lead-free terminations

(1) Inductance is measured by LCR-meter 4284A (Agilent) or equivalent.
(2) DC resistance is measured by Digital Multimeter TR6871
(Advantest) or equivalent.
(3) Maximum allowable DC current is that which causes a 30% inductance
reduction from the initial value, or coil temperature to rise by 40°C,
whichever is smaller. (Reference ambient temperature 20°C). Rated DC
current for a 10% inductance reduction is provided as well.
