NPOXERXZR_YEV Ceramic Chip Capacitors Overview
This KOA Speer Electronics, Inc. datasheet presents information on the NPOXERXZR_YEV series of ceramic chip capacitors that are compliant with the EU’s RoHS directive. These capacitors feature a high Q factor, low temperature coefficient (TC.C), and are available in various high capacitance values, up to 100 pF. They come with lead-free terminations and thus meet environmental safety standards.
Dimensions and Construction
The ceramic chip capacitors are available in standard case sizes, including 0402, 0603, 0805, 1206, and 1210. Each size has specified maximum dimensions in inches and millimeters. Components consist of a ceramic body, solder plating (Sn), silver metallization electrodes, and a selection of termination materials.
Ordering Information
To order the correct capacitor, one must specify dielectric, size, voltage, packaging, capacitance, and tolerance. Capacitance values use two significant digits plus the number of zeros, with “R” indicating a decimal point. Tolerance designations range from ±0.1 pF to ±20%, including increments and differing ranges such as ±5% and +80/-20%. Various voltage ratings, from 6.3V to 200V, correspond to different sizes and dielectric choices.
Packaging Options
Packaging for these capacitors includes 7″ paper or embossed plastic tape for most sizes, with an additional 13″ paper or embossed plastic tape available for certain cases.
Applications and Ratings
Key performance specifications are provided, like dissipation factor, temperature coefficient (TCC), insulation resistance, and voltage ratings. These define the operating envelope for different dielectric materials under NPO, XSR, X7R, and YSV categorization. The operating temperature range is from -55°C up to +125°C, depending on the dielectric type. Insulation resistance values are given with minimum requirements at +25°C. The datasheet outlines the test voltage to be 1.0 + 0.2 Vrms for all the dielectrics mentioned.
Capacitance Voltage Availability
The datasheet lists out available capacitance and voltage values for the sizes 0402, 0603, 0805, 1206, and 1210. For each size and dielectric type, a table of values and codes details the options for capacitance ranging from as low as 10 pF to as high as 22,000,000 pF with various tolerance levels.
Finally, specifications may be subject to change without prior notice, and the datasheet encourages users to confirm specifications before ordering or using the capacitors. This highlights the importance of reviewing the latest datasheet for accurate information. The document closes with contact details of KOA Speer Electronics for further inquiries.
