TDK Ceramic Capacitors: CeraLink Capacitors with Modular Flexible Assembly Technology

TDK Ceramic Capacitors

TDK Corporation (Tokyo Stock Exchange: 6762) Introduced CeraLink FA type capacitors with modular flexible assembly technology to further expand the lineup of proven CeraLinkTM capacitors. The new type of capacitor has a space-saving design with two, three or even ten identical capacitors connected in parallel on the same terminal to increase the capacitance. CeraLink FA type capacitors are available in 500V DC, 700V DC and 900V DC ratings with capacitance values between 0.5μF and 10μF depending on the rated voltage and the number of capacitors. These PLZT (lead zirconate titanate) ceramic capacitors have a unique bright spot that allows an operating temperature of up to 150 °C. The FA type capacitor is 7.4 mm wide, 9.1 mm high, and has a length of 6.3 mm, 9.3 mm, or 30.3 mm. Despite their small size, they have an absorption ripple current capability of up to 47 ARMS.

One of the main advantages of shunt switches is their ultra-low ESR (equivalent series resistance), which is significantly below 10 mΩ over a large frequency range of 0.1 to 1 MHz. Even at the minimum 3nH inductance, the ESL (equivalent series inductance) is extremely low. With weak parasitics, CeraLink capacitors are well suited for converter topologies based on fast switching semiconductors such as GaN or SiC, and the overcharge voltage during conversion is significantly lower than conventional capacitor technology. In addition, CeraLink capacitors can easily meet the special requirements of size, current capacity, and temperature.
