FeaTuRes
Meet SONY SS-00259's criteria for lead-free product.
Ceramic body and wire wound construction provide highest SRFs.
These ultra-compact inductors provided exceptional Q values, even at high frequencies.
Their ceramic construction delivers the highest possible SRFs as well as excellent Q values.
The non-magnetic coil form also assures the utmost in thermal stability,predictability and betch con-
sistency.
Atjust 1.02mm high,CT0805 is the lowest profile SMD inductor among 0805 series.
Tolerance :G=±2%, J=±5%, K=±10%
