Overview
KOA Speer’s NPOXERXZR_YEV series are high-performance ceramic chip capacitors designed to meet various electronic industry requirements, including EU RoHS compliance for lead-free terminations. With a high Q factor and low Temperature Coefficient of Capacitance (TC.C), these capacitors are suitable for applications requiring precise performance and stability. The series boasts a wide range of capacitance values, reaching up to 100 pF.
Construction and Dimensions
The capacitors are offered in several standard case sizes such as 0402, 0603, 0805, 1206, and 1210, with maximum size dimensions varying according to the case type. Each capacitor features a ceramic body with silver metallization and solder plating made of tin (Sn).
Ordering Information
To order, select from various terminations, dielectrics, sizes, voltages, packagings, capacitance, and tolerances. The capacitance tolerance range features tight precision starting from ±0.1pF and includes broader ranges up to +80/-20%. Packaging options include 7-inch and 13-inch paper or embossed plastic tape.
Applications, Ratings, and Environmental Specifications
The capacitors come in different dielectrics such as NPO, XSR, X7R, and YSV, each with specific capacitance-voltage ratings, dissipation factors, temperature coefficients, test voltages, and operating temperatures. For example, NPO dielectrics offer exceptional stability with a Temperature Coefficient of Capacitance (TCC) of 0 ± 30 ppm/°C and a Q factor of 400. In contrast, X7R dielectrics allow for a broader temperature range but with a more varied TCC. Insulation resistance is also specified, ensuring reliability under various temperature conditions. The full environmental specifications can be obtained through KOA Speer’s official website.
Capacitance and Voltage Availability
The datasheet lists specific capacitance values and corresponding codes for various sizes, emphasizing the availability of certain values based on the case size. For instance, capacitance tolerance for values greater than 30 pF is ±0.1%, a standard of precision for the electronic components industry.
Note: The specifications mentioned may be subject to change, and users should always confirm technical specifications prior to ordering or using the capacitors.
