Packaging Q’ty (g) Reel (pcs) 0.06 4000 The re-flow condition / taping dimensions are explained on P197, 198 of our catalog. ( ): Please use AK,RK or J2 to indicate terminal type. Note : 1. Do not use reflow soldering when cell voltage is above 0.3 V. 2. When the capacitor is being used in a high temperature and high humidity environment for a long period, and will not affect any electrical characteristics of the capacitor. 3: EP series is a small capacitor that developed for the RTC backup of cellular phone. Therefore, there isa a possibility that it will not be able to back up in short time depend on using condition. Please contact us before you use it Design and specifications are each subject to change without notice. Ask factory for the current technical specifications before purchase and/or use.
