On this slide, TDK’s part number nomenclature is highlighted. The first three characters will reveal the series name followed by a 1 character alpha code relating to the case size in millimeters. Next, there will be a thickness code to specify nominal thickness. Following thickness, a numeric code is used for operating life test conditions per, AEC-Q200 requirements. The product is tested “x” times the rated voltage at maximum operating temperature for 1,000 hours. The CGJ series specifically is tested for 2,000 hours. The next designation is the temperature characteristic, which determines the maximum allowed capacitance with respect to room temperature. The Rated Voltage indicates the maximum recommended operating voltage and is specified by a TDK alpha numeric code. The nominal capacitance is expressed in scientific notation and in pF. TDK recommends referencing the E-Series standard for optimal capacitance value selection. Choosing a capacitance value from the E-Series guide, can provide delivery, pricing, and overall support benefits. The Capacitance Tolerance is designated by an Alpha Code and reflects the change in capacitance under industry standard testing procedures for MLCCs. Following tolerance, the next 3 numeric characters are the thickness code. The Packaging Code specifies Reel Size and Pitch in millimeters. The final character is a special code which can relate to design considerations such as soft termination, open mode, or conductive epoxy.
