High-voltage, screw-mounting disc-capacitors
with values up to 8000pF
Vishay Intertechnology introduced a new series of high-voltage,
screw-mounting disc capacitors that offers designers a wide
range of diameters and capacitance values over rated voltages
from 10 kVDC to 40 kVDC.
With low AC and DC coefficients, and negligible piezoelectric/electrostrictive
effect, the Vishay Cera-Mite 715CxxKT series has been specifically
designed to function in circuits with high peak current
and high repetition rates. The new devices are optimized
for high-frequency coupling and decoupling, laser excitation,
and fast-repetition pulse circuitry in high-voltage power
supplies, CO2 lasers, X-ray equipment, and welding equipment
where low losses and high permittivity are required.
Features include:
1. The 715CxxKT series capacitors feature a low dissipation
factor of 0.2 % at 1 kHz and a N4700 (T3M) Class
1, strontium-based ceramic dielectric.
2. The devices offer designers a capacitance range up to
8000pF at 10 kVDC and 2000pF at 40 kVDC, and
diameters ranging from 21 mm to 60 mm.
3. Providing a drop-in replacement for similar devices,
the 715CxxKT series features both English and metric
screw terminals and is epoxy resin encapsulated.
4. Vishay Cera-Mite single-layer ceramic capacitors, available
from 100 V through 40,000 V, can be used
in power supplies, electronic lighting, EMI/RFI filtering,
and aerospace and industrial applications.
5. The products include a range of ceramic disc capacitors,
including AC-line-rated disc capacitors - rugged,
high-voltage capacitors specifically designed and tested
for use on 125-V to 600-V power sources.
6. Certified to meet Y- and X-type safety agency requirements,
they can be used in across-the-line, line-to-ground, and
line-bypass filtering applications.
Availability: Samples and production quantities
of the 715CxxKT series are available now, with a lead-time
of eight weeks for larger orders.
