During the past two years Yageo has developed ceramic capacitors with very thin dielectric layers and high capacitance. According to the company, newly-set-up production lines for these Phycomp-branded capacitors in The Netherlands and Taiwan guarantee sufficient volume to replace tantalum capacitors in many applications and enable customers to benefit from better electrical characteristics at lower cost.
The Phycomp capacitors show very low ESR and ESL, and this results in superior high frequency behaviour and very low heat dissipation. Compared to tantalum, benefits are: better overall performance; lower ESR and ESL; smaller size; higher reliability with regards to applied voltage; higher ripple current rating; higher Q-factor; smaller capacitance needed for the same application.
The Phycomp high capacitance multilayer ceramic capacitors are recommended for smoothing circuitry, decoupling and coupling circuitry. The family covers X5R, X7R and Y5V type capacitors. Capacitance values from 220 nF (0402) up to 100 μF (2220) are available in various package sizes and voltage ratings. Development is on-going - products expected in the near future are 1 μF in 0402, 100 μF in 1206 and 220 μF in 1812 as well as capacitors with upgraded voltage ratings.
