1.Using the original high density coil
The unevenness of the impedance is small. Panasonic ability 3σ: ±15%
Competitor ability 3σ: ±20 to 25%
2.60Ω-1A, 120Ω-0.5A are achieved by 1608
size. (The highest Rated Current and low DC
Resistance in industry in 1608 size)
1.Low Rdc(3 to 8mΩ)
•Low voltage drop for power line
•Heat of components is small.
•Low power loss for portable equipment
2.Thinner body (t = 0.9mm or 1.1mm)
•The effect is demonstrated with a thin
equipment.
2.The compatibility characteristics with
competitor (high speed signal type) is valued.
•Can replace and describe parallel of P/N
because of equal the size & characteristic
3.GHz correspondence by improvement of
own resonance frequency
