Static electricity Removal Characteristics
Note) Static electricity elimination features are based on data from using a charged plate (size: 150 mm x 150 mm, capacitance: 20 pF) as defined in the U.S. ANSI standards
(ANSI/ESD, STM3, 1-2000). Use this as a guideline for model selection only because the value varies depending on the material and/or size of the subject.
