No more compromises between stability and capacitance! The brand new C48X material combines most advantages of NPO and X7R dielectrics, enabling the new high power and high frequency ceramic capacitor range to provide great stability in voltage, high capacitance, great dissipation factor and fast charge/discharge.
Miniaturization is a driving need for future electronics pieces of equipment. This evolution, true whatever the application, leads Exxelia Technologies (ex-Eurofarad) to develop a brand new high voltage ceramic capacitors range based on a new dielectric material named C48X, combining most of the advantages of NPO and X7R dielectrics.
Compared to X7R material, C48X dielectric allows to get the same capacitance values under working voltage with the unrivaled advantage of a very low dissipation factor (less than 5.10-4). Besides, it can also withstand very high dV/dt, up to 10kV/μs, which makes it the solution of choice for pulse and fast charge/discharge applications. Thus capacitors with C48X dielectric appear to be ideally suited for power applications where heat dissipation may be detrimental to performances and reliability.
Exxelia Technologies’ capacitors based on the C48X material have been developed from 200V to 5kV with chip sizes ranging from 1812 to 16080, allowing a maximum capacitance value of 10μF 200V (10 times more than with an NPO ceramic). The standard stacked versions are proposed with a maximum capacitance value of 47μF 200V.
Regarding the mounting of these capacitors, many configurations are possible to be compatible either with surface mounting or through-hole mounting. All these versions can be suitable for space use and can be designed in order to avoid any whisker growth risk (10% min lead in all tin-lead alloys used). The introduction of the C48X range in the EPPL (European Space Agency Preferred Parts List) for space is in progress for sizes 0603 to 6560 from 100V to 1kV up to size 1210 and up to 5kV until the size 6560).
Some typical applications:
• 400Hz Aircraft
• Precision/filtering capacitance in thermally challenged environment for AC or DC voltage
Introduction of DSCC 93026 qualified Wet Tantalum Capacitors
Exxelia’s range of wet tantalum capacitors WT84 is now fully qualified to DSCC 93026 drawing for voltages from 25V up to 125V. Available in all case sizes (T1, T2, T3, T4) the family is housed in a hermetically sealed tantalum case and is designed to withstand the most stringent environmental constraints. Thanks to the continuous improvements conducted in the manufacturing processes combined with the high purity tantalum powder used by Exxelia, DSCC 93026 provides the highest capacitance per unit volume. In addition, compared to conventional wet tantalum capacitors, DSCC 93026 features much lower ESR and higher ripple current. DSCC 93026 is qualified for capacitance values range from 10µF up to 1800µF at voltages from 25V up to 125V, and with operating temperatures of -55°C to 125°C. The series is ideal for use in high-reliability defense, avionics, radars and power supply applications requiring high capacitance or high energy storage. DSCC 93026 is available now for order.
