The “X” designator specifies tape and reel packaging.
V
Minimum L incorporates tolerance, temperature, and partial saturation effects (L decreases with increasing current).
Minimum C is a function of initial tolerance, maximum temperature, and the effective capacitance being reduced due to
frequency, dielectric, and voltage bias effects.
