On October 19, 2013, AVX, a leading manufacturer of passive components and interconnect solutions, released a groundbreaking technical paper titled "Media Absorption of Multilayer Organic (MLOâ„¢) Capacitors," highlighting its advantages over other technologies. The MLO capacitor demonstrates the lowest dielectric absorption (DA), making it particularly suitable for sample-and-hold circuits. In such circuits, the capacitor's voltage is expected to remain stable during the hold phase, but differences in DA can lead to voltage errors.
According to media absorption measurements conducted under the MIL-C-19778 test, AVX’s MLO capacitors exhibit an impressive 0.0015% media absorption. For comparison, Teflon, known for its low DA, shows less than 0.01%, while NP0 ceramic has a DA of 0.6%. This significant improvement positions the MLO capacitor as a superior choice for high-precision applications.
Edgardo Menendez, an application engineer at AVX, stated, “Thanks to our proprietary MLO material technology, our capacitors achieve ultra-low DA, which is much lower than many other dielectric materials. This makes them ideal for sample-and-hold circuits where even small DA variations can cause output errors.â€
AVX’s MLO capacitors are built using advanced fabrication techniques and unique component design topologies, ensuring high Q performance. As a low-loss RF component, they maintain stability across a wide frequency range and are compatible with most FR4 printed circuit boards. These capacitors are available with voltage ratings up to 500V, offering versatility for a variety of high-performance applications.
