SMPS Capacitors Chip Assemblies
CH/CV - Radial, Dual-in-Line,
4 Terminal/SMT J & L Ranges
The CH/CV range exhibits low ESR/ESL making them well suited for high
frequency applications. With its PME technology, the range exhibits high current
handling capabilities where as other technologies may not, making them the ideal
choice for filtering, smoothing and decoupling circuit applications.
The CH/CV range uses a number of different lead frames types which reduces the
thermo-mechanical stresses which makes them the designers choice for high
reliability applications. In combination with this the range uses a stacked capacitor
design which saves on PCB space.
FEATURES
BS9100 approved
Voltage range 50-500 V DC
Dielectrics 1B/COG and 2C1/X7R
Customised ceramic capacitor packages and lead frames available.
Note: AVX does not recommend or advise the use of adhesives to secure the CH/CV components
to the PCB
