- Design Support
Film capacitors generally have excellent electrical characteristics, but their large shape has been a problem.
The PMLCAP uses a vacuum deposition method to form the dielectric, resulting in a significantly smaller and larger capacitance compared to conventional film capacitors.
It is an ideal component for electronic devices that require high performance and high-density mounting. We are also working on this product for automotive inverter circuits.
The dielectric polymer is submicron thickness
Structure of PMLCAP piles up dielectric thin film and
inner electrode (aluminum) in turn.
Achieved small size, lightweight and high capacitance compared with
conventional film capacitors.
The dielectric material which has excellent temperature characteristics is selected
Within category temperature range, capacitors have excellent temperature characteristics, and capacitors can be used without voltage derating.
Excellent characteristics “less buzz” and “no capacitance change by DC bias” due to no piezoelectric effect.
Ideal high quality parts for sound equipment with less harmonic distortion, using a dielectric thin film polymer formed by vacuum deposition.
Avoidance of risk of ignition and smoking
The risk of ignition and smoking are decreased by using non-self-ignition materials.
Low dielectric absorption
Characterized low dielectric absorption by using dielectric of low dielectric absorption.
Cautions for Proper Use
What is the service life of a PMLCAP?
The service life of a PMLCAP varies greatly depending on the conditions of use, particularly if it is used at a higher voltage than the rated voltage or in a hot and humid environment.
Please contact Rubycon in advance for further information.
Is voltage derating necessary if the PMLCAP is used in the category temperature range?
The dielectric material used in a PMLCAP has superior heat resistance. Therefore, voltage derating is not necessary.
How is the buzz characteristic?
One of the benefits of PMLCAP is very low buzz when AC is applied, due to the high adhesion between the layers.
Please try using PMLCAP in any of your circuits that require quietness.
