FEATURES
Meet Sony SS-00259’s criteria for lead-free product.
Ceramic body and wire wound construction provide highest SrFs.
These ultra-compact inductors provide 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 batch
consistency.
At just 1.02 mm high, CT0805 is the lowest profile SMD inductor.
