RUBYCON PMLCAPs as Drop-In PEN Replacement
PEN Alternative Without Layout Changes
Due to the discontinuation of Polyethylene Naphthalate (PEN) film, there is a growing need for electrically and mechanically compatible replacements for many SMD film capacitors. With its PMLCAP series, RUBYCON offers a range of polymer multilayer capacitors that are ideally suited for design-to-design replacements – without the need for time-consuming layout modifications.

The MU, MF, NS, and MS series cover a wide range of standard capacitance values within a voltage range of 10V to 200V, making them a reliable alternative to traditional PEN-based solutions.
Key Technical Advantages Over PEN Film Capacitors
- Smaller footprint for equivalent capacitance → ideal for compact or optimized layouts
- Low ESR and ESL → improved high-frequency performance and reduced parasitic inductance
- High insulation resistance and thermally stable capacitance
- No piezoelectric effect → suitable for transient or AC-containing signals
- Low temperature coefficient and minimal aging → high long-term reliability
- No DC bias derating → stable capacitance under DC conditions
- Non-polarized design → flexible placement in the layout
