For low current and low power are made in cases resembling resistors. An ohmmeter readily distinguishes them from similar-sized resistors by showing the low resistance of the inductor. What Stands Out ... These inductors provide a 33uH inductance value, making them ideal for RF applications that require stable performance and low signal loss The fourth band represents the tolerance. Features: Color Rings:The first two of these represent a two-digit significant number.
