Radial Leaded Multilayer Ceramic Capacitors
Goldmax, 300, Conformally Coated, C0G Dielectric, 25 – 200 VDC (Commercial Grade)
Qualication/Certication
Commercial Grade products are subject to internal qualication. Details regarding test methods and conditions are
referenced in Table 2, Performance & Reliability.
Environmental Compliance
Lead (Pb)-free, REACH and RoHS compliant without exemptions when ordered with a 100% tin (Sn) wire lead nish.
Product ordered with tin/ lead (Sn60/Pb40) wire lead nish do not meet RoHS criteria.
