Digi-Key - Multilayer ceramic capacitor range offers versatile range of solutions

Recent advances in ceramic material and package technologies have increased
the choices for a designer when selecting the best capacitor for by-passing,
de-coupling, filtering, and non-critical timing circuitry. These Panasonic
products, now available from Digi-Key, feature technology improvements that
make it possible to add more capacitance into smaller case sizes while
maintaining the largest possible operating voltage, improving the electrical
performance and lowering the cost of MLCC Capacitors.
A designer is no longer restricted to SMT (chip aluminium electrolytic or
chip tantalum). The superior equivalent series resistance (ESR), equivalent
series inductance (ESL), impedance and reliability of MLCCs can now be found
in the higher capacitance values.
The improved MLCC mechanical and electrical attributes enable designers to
make electronic products smaller with less weight, better electrical
performance, and at a lower cost; thereby making the designer's products
more competitive. Product features include small size and high capacitance,
low ESR/ESL and 'excellent' high-frequency characteristics. The devices are
seen as ideal alternatives to tantalum chip capacitors and aluminium
electrolytic capacitors
Typical applications include portable electronics, medical devices, test
equipment, instrumentation, mobile phones, RF modules, control equipment,
power supply circuitry, decoupling applications and W-LANs, says the
company.
