M.D.L. The NP Non-Polar / BP Bi-Polar Series AXIAL Type E-Caps are non-polarized / bi-polar aluminum electrolytic capacitors specially designed for audio and loudspeaker applications.
Featuring an axial lead configuration, these capacitors are suitable for speaker crossover networks, audio filtering, signal coupling, and other AC signal applications where voltage polarity may periodically reverse.

The NP Non-Polar / BP Bi-Polar Series utilizes aluminum foil, electrolytic paper, electrolyte, and other carefully selected materials to provide reliable electrical performance for audio applications.
The axial lead construction provides leads at both ends of the capacitor, making the component particularly suitable for horizontal mounting, point-to-point wiring, and applications where flexible component positioning is required.
The series is designed for use in audio equipment and loudspeaker systems, including speaker crossover networks, where capacitors are commonly used for high-frequency, mid-frequency, and low-frequency signal filtering.
Unlike standard polarized aluminum electrolytic capacitors, NP/BP capacitors are designed to operate with AC signals and periodically reversing voltage polarity, making them suitable for applications where a conventional polarized capacitor may not be appropriate.
The axial construction also provides convenient installation flexibility and makes the series suitable for both traditional and high-performance audio equipment, loudspeakers, and crossover networks.

For audio applications, a lower Dissipation Factor (DF) generally indicates lower capacitor losses and better AC performance.
M.D.L. offers different DF levels, allowing customers to select the appropriate balance between performance, size and cost according to their application requirements.
Lower DF → Lower Loss → May Require Larger Size / Higher Cost
A lower DF specification may require a larger capacitor construction, resulting in a larger physical size and higher cost.
