Film capacitor series keeps its cool even at 150°C

High-temp film capacitor, stays cool up to 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.

Larger Batches of High Q-Factor Dielectric Resonators

Dielectric resonators are designed to replace resonant cavities in microwave functions such as filters and oscillators. Exxelia with the support of ESA and CNES developed the E7000 series that provides a narrow bandwidth with smaller size. E7000 is Ba-Mg-Ta materials based that combines an ultra-high Q-factor and the possibility to get all the temperature coefficients upon request. E7000 features the high-performance requested for space use in the frequency range from 5 to 32 GHz, and guarantees up to Qxf > 250 000 at 10GHZ. Being one of the few manufacturers producing its own raw materials, Exxelia perfectly masters the production of dielectric resonators. Induced by the success of this new range, the company is now able to provide larger batches (up to 20kg of powder) of its E7000 series while keeping the exact same product properties, resulting in opportunities for cost-effective volume fabrication. Typical applications for the E7000 series: Satellite multiplexing filter devices, radio links for communication systems (LMDS), military radars.  

Exxelia unveils the new Rectangular Aluminum Electrolytic Capacitors

In the small world of "Rectangular Aluminum Electrolytic Capacitors", the new Cubisic SLP is a real “game changer”! Providing twice as much capacitance as any other "Rectangular Aluminum Electrolytic Capacitor" available on the market in the exact same volume, this new series also offers more than twice the lifetime.  Engineers tackling complex designing requirements and looking for an easily integrable product will save space and gain reliability thanks to the use of improved materials. Because the CUBISIC SLP can resist 50G vibrations and withstand 92,000 feet altitude, it is perfectly suitable for cockpits, actuation and power generation functions of commercial and military aircrafts, as well as radars and laser systems. SPECIFICATIONS: Capacitance from 100μF to 68 000μF Voltages from 10V to 450V Life time of 5000 hours at 85°C Operating Temperature -55°C to +85°C 50g vibrations / 92,000 altitude RoHS compliant configurations available
