U2J Capacitors

Date Added: Thursday, July 21, 2016

U2J is an extremely stable dielectric material for Class I multilayer ceramic capacitors (MLCCs). Ceramic capacitors using the U2J dielectric retain over 99% of nominal capacitance at full rated voltage.

Understanding Ceramic’s Capacitance Over Temperature Performance

Date Added: Tuesday, March 22, 2016

Understanding the change in capacitance over temperature for ceramic capacitors is important in many applications. With this post, how temperature affects ceramic capacitor dielectrics such as C0G, X7R, and U2J.

Audio Equipment

Date Added: Wednesday, April 6, 2016

High-quality audio equipment needs high-end components. Film and C0G capacitors are standard in audio designs. They offer excellent DC block and no piezoelectric noise (or microphonics.)

Building Stronger KONNEKTions

Date Added: Thursday, April 25, 2019

KONNEKT utilizes an innovative transient liquid phase sintering (TLPS) material to create a leadless multi-chip solution. KONNEKT enables a low-loss, low-inductance package capable of handling extremely high ripple currents in the hundreds of kilohertz (kHz) when combined with KEMET’s ultra-stable U2J dielectric. Learn about why this solution was used for a large technology giant’s unique needs.
