New Yorker: New Material for High-Voltage Capacitors
Northvale, NJ — New Yorker Electron ics is now distributing ceram- ic capacitors with the new C48X dielectric material from Exxelia Technologies (ex-Eurofarad). These high-power capacitors have low heat dissipation, making them suitable for applications in aircraft, defense and space.
The C48X material combines
most of the advantages of NPO and X7R dielectrics, enabling the new high-power and high-frequency ceramic capacitor range to provide great stability in voltage. This elimi- nates the need to compromise between stability and capacitance. They also deliver high capacitance, great dissipation factor and fast charge/discharge. Compared to X7R material,

C48X dielectric supplies the same capacitance values under working voltage with the advantage of a very low dissipation factor. It can also withstand very high dV/dt, up to 10 kV/µs, which makes it the solution of choice for pulse and fast charge/dis- charge applications or firing units. Therefore, capacitors with C48X dielectric appear to be best suited for power applications where heat dissi- pation may be detrimental to per- formances and reliability. Driven by industry demands for
miniaturization, Exxelia Technol - ogies’ capacitors based on the C48X material have been developed from
200V to 5 kV with chip sizes ranging from 1812 to 16080, allowing a maxi- mum capacitance value of 10 µF, 200V. The standard stacked versions are proposed with a maximum capac- itance value of 47 µF, 200V.
Ceramic capacitors with C48X material.
Many mounting configurations
are possible with either surface or through-hole mounting. All versions can be used for space applications and can be designed in order to avoid any whisker growth risk. The intro- duction 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 1 kV, up to size 1210.

Ensign Intros Industrial Control Transformers
Bellevue, IA — Ensign Corporation has introduced its KA series of indus- trial control transformers with power ranges from 25V to 5 kV, 120 or 240 VAC input and 12 or 24 VAC output. The series’ compact design meets various international safety agency approvals, such as UL, CSE and CE. The transformers are especially
suited for high inrush current and output voltage stability. They are useful for typical electromagnetic device applications, including relays, motors, solenoids, contactors, bells, signals, and alarm systems. Features include IEC "touch-
proof" terminals, slotted mounting holes for quick and easy mounting, copper coils, high-quality steel for low excitation current, and an oper- ating temperature range of –20 to +40°C (–4 to 104°F). Ensign provides transformers
with a highly-experienced staff of engi- neers, both standard and custom prod-
KA series industrial control transformer.

Vincotech Intros Symmetric Power Boost Modules
Unterhaching, Germany — Vincotech has launched a new line of symmet- ric boost modules, flowBOOST 1 symmetric. Engineered to deliver top switching frequencies of up to 50 kHz, the modules are able to provide a symmetric boost in 1,300V or a buck boost in 650V applications. They enable the use of smaller and lighter passive power components to decrease system sizes. Equipped with the latest 650V
Infineon TRENCHSTOP™ IGBT5 (H5 and S5) to boost efficiency and
cut system costs, the modules deliver excellent performance at high speeds and low saturation voltage. They support 100 and 150A applications, come in low-inductive 36 x 82 mm (1.4 x 3.2 in.) housings, and are a solution for downsizing bulky trans- formers and DC link capacitors.
