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 performance in comparison to other technologies. The MLO capacitor stands out for having the lowest dielectric absorption (DA), making it particularly well-suited for sample-and-hold circuits.
In these circuits, the capacitor is expected to maintain a precise voltage level during the hold phase. However, variations in dielectric absorption can introduce unwanted voltage errors. AVX's MLO capacitors address this issue effectively due to their ultra-low DA.
According to media absorption measurements conducted under the MIL-C-19778 test standard, AVX's MLO capacitors exhibit a remarkable 0.0015% media absorption. For reference, Teflon, known for its low DA, showed less than 0.01%, while NP0 ceramic had a DA of 0.6%. This demonstrates the superior performance of AVX's MLO technology.
Edgardo Menendez, an application engineer at AVX, explained, "Thanks to our proprietary MLO material technology, our capacitors achieve ultra-low dielectric absorption—lower than most other dielectric materials. This makes them ideal for sample-and-hold circuits, where even small DA variations can lead to significant output errors."
AVX's MLO capacitors are built using advanced fabrication techniques and innovative design topologies, resulting in high Q values and minimal loss. These RF components maintain stability across a wide frequency range and are compatible with most FR4 printed circuit boards. They are available with voltage ratings up to 500V, offering reliable performance in demanding applications.
