MLZ Decoupling Circuit Multilayer Fixed Inductors TDK MLZ Decoupling Circuit Multilayer Fixed Inductors feature high DC superimposition characteristics and low DC resistance. Ranging in size from 0402 to 0805, the MLZ components are compatible with wide frequency band noise, from low to high frequency. H-type products have a rated current that is equivalent to that of wound coils. W-type devices have both large current and low resistance, and the L-type inductors have up to 60% lower resistance than the W-type products.
