Nouvelle gamme qualifiée DSCC 93026 de condensateurs au tantale
Exxelia a reçu la qualification DSCC 93026 du Defense Supply Center Columbus (DSCC) pour ses condensateurs au tantale WT84.
La gamme Exxelia de condensateurs au tantale gélifiés WT84 est désormais qualifiée DSCC (réf. DSCC 93026).
Conçus avec un boîtier au tantale cylindrique et hermétique, les DSCC 93026 sont proposés dans des tailles de boîtier standard de T1 à T4, avec terminaisons axiales. Grâce à l’utilisation d’une poudre au tantale d’une grande pureté les DSCC 93026 offrent la capacité par unité de volume la plus élevée du marché. Comparés à des condensateurs au tantale gélifiés classiques, les DSCC 93026 présentent un ESR nettement plus faible et un courant d’ondulation plus élevé.
Les DSCC 93026 sont qualifiés pour des tensions de 25V à 125V, avec des valeurs de capacité comprises entre 1800 μF @25V and 10 μF @125V. La série DSCC 93026 offre une grande capacité de stockage d’énergie sur une plage de température de fonctionnement étendue (-55°C à 125°C). C'est une gamme destinée aux applications de défense, avionique et radars.
Film capacitor series keeps its cool even at 150°C
The Exxelia Dearborn 880P series of metalised Polyphenylene Sulfide (PPS) Film Capacitors is designed to keep cool when things get hot. With an operating temperature range of -55 to +150°C, they experience no derating for DC operations and none in AC operations up to +125°C. This enables them to function at full capacity in extreme heat applications. The ability to operate at such high temperatures can eliminate the need for a cooling system within the design, thus reducing overall design time, weight and space. PPS is a high-temperature, low-loss dielectric film used in the 880P series of wrap-and-fill capacitors. This allows them to feature superior electrical characteristics over an extremely wide temperature range and maintain excellent capacitance stability in one rugged, lightweight package. It performs consistently well in commercial applications such as in power supplies and in more demanding applications, such as in avionics, on a congested control or instrumentation panel. The series features a capacitance range of 0.0047 to 10.0µF and voltage ratings from 50 to 400VDC with precision tolerances as low as ±¼% through ±10% yielding greater accuracy of capacitance. It is also a customisable unit with voltage maximums of 700 – 800VDC at 125°C maximum (higher voltages are available at reduced capacitance). Made in the USA, the units are highly durable and capable of withstanding a five-pound pull force on lead axis. They are non-polar and demonstrate low loss factor, good voltage breakdown strength and high insulation resistance (low leak current) – and are completely stable over normal temperatures, voltages and frequency ranges. These characteristics allow the 880P series capacitors to deliver high performance in a variety of applications such as DC timing circuits, low- to high-frequency AC applications, and pulse or energy discharge uses. Additionally, the package has axial leads with moisture-resistant, flame-retardant epoxy end seals and an outer tape covering for maximum performance.
Magnetic Components based on Adaptive CCM Technology at APEC – Booth# 653 –
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.
