Exxelia will exhibit the CCM series during the Applied Power Electronics Conference at Exxelia’s booth #623 from March 27-30, 2017 in Tampa, FL.
Exxelia designed CCM technology to respond to the growing interest of electronic engineers for inductors and transformers with multiple outputs, high power density and reduced footprint.
Qualified for aeronautic and space applications, the CCM product line features terrific robustness. The monolithic design provides high mechanical performance, proven by the successfully testing in accordance with MIL-STD-202 (methods 213 and 204).
The series offers five different sizes, allowing optimized component design in a pick-and-place surface mount (SMD) package. Through-hole (TH) packages are also available upon request. The CCM series is particularly flexible with a number of pins options available, from 2×6 pins for the smallest package, up to 2×10.
CCM transformers and inductors can operate over a wide temperature range with a minimal temperature of -55° C. The standard thermal grade of the technology is 140° C. Thanks to the technology design, the thermal resistance is 30% lower than standard industrial components. The epoxy molding protecting the winding ensures a lower temperature gradient and a better heat dissipation. Each unit is thoroughly tested with a dielectric withstanding strength of 1,500 VAC. Component materials meet UL 94-V0 rating.
Exxelia can evaluate losses and related temperature rise thanks to an in-depth knowledge of CCM technology. Thermal resistance data is available for each package size. Exxelia can also manufacture products in CCM technology according to MIL-STD-981.
WT83 - HIGH CAPACITANCE WET TANTALUM
Capacitance values have been strongly increased with Exxelia's new range of tantalum capacitors: WT83 is an extension of the ST79 families (according to CLR93 MIL values) but with double the capacitance. That is a pass for impactful miniaturization of existing designs by playing on both size and weight (for instance, WT83 offers 470µf 100V in a D size, whereas ST79 only gives 220µF in the same other conditions).
Low Voltage 0402 MLCCs now in ESA QPL
Exxelia ranges of low voltage MLCC for surface mounting, CEC19 and CNC19, have achieved the Qualified Part List (QPL) status under the criteria of the European Space Component Coordination’s (ESCC) 3009/042 and 3009/043 respectively. The case size 0402 QPL-qualified parts are available from 10V to 25V, enabling substantial miniaturization and cost-saving. Dielectrics are based either in the very stable NPO (type 1) or the high capacitance X7R (type 2). CEC and CNC series combine high capacitance values with high thermal and voltage stability. Versions with polymer terminations are also QPL-certified. These ranges of versatile chip capacitors are intended for use in a wide variety of aerospace applications requiring the highest level of reliability: satellites, launch vehicles, payloads, etc. CEC19 features: - very stable NPO dielectric - maximum capacitance values: 330pF in 10V, 120pF in 16V and 100pF in 25V, - large operating temperatures: -55°C to 125°C CNC19 features: - high capacitance X7R dielectric - high capacitance rating values: from 68pF to 12nF in 10V, 8.2nF in 16V and 5.6nF in 25V - large operating temperatures: -55°C to 125°C
