M.D.L. MER Series Metallized Polyester Film Capacitors, Non-Inductive
The M.D.L. MER Series uses the same metallized polyester film, OFC copper leads and basic winding process as the MET, MEF and MEC Series.
After winding, the capacitor element is flattened for radial vertical mounting. Its exterior is then insulated using an epoxy resin spray or dip-coating process.
【Special Note】: We use OFC oxygen-free copper leads. Low-end MER capacitors on the market typically use aluminum or iron leads. All M.D.L. capacitors sold by our company use OFC oxygen-free copper leads. You can distinguish genuine products from counterfeit ones by scratching off the plating on the leads or using a magnet.

Product Overview
M.D.L. MER Series Metallized Polyester Film Capacitors
-
he MER Series shares comparable fundamental electrical characteristics with the other ME Series. Its primary differences are the exterior finish and mounting configuration—not performance grade.
During production, the wound capacitor element is formed into a flat oval shape and covered with an epoxy resin insulating layer. The epoxy coating provides surface insulation and basic external protection while maintaining a direct and simple vertical package.
Both leads extend from the same side of the MER body for vertical PCB mounting. Unlike the MEC Series, the MER does not use a separate rectangular plastic case. Selection can therefore be based on body shape, lead spacing, available installation space and finishing requirements.
Key specifications:
- Construction: Radial lead, flat oval body
- Exterior finish: Epoxy resin spray or dip coating
- Mounting: Vertical PCB mounting
- Working voltage: 100VDC to 250VDC
- Operating temperature: −40°C to +105°C
- Lead material: OFC copper
- Winding: Non-inductive
Typical applications include:
Vertically mounted loudspeaker crossover networks Audio and filtering circuits Car audio and speaker equipment Communication and signal-processing equipment Instruments and industrial controls General printed circuit boards and electronic equipment
