Power Electronics & Filtering Capacitors

1800µF High-Power Water-Cooled DZMJ DC Filter Capacitor

Designed for high-power DC filtering applications requiring water-cooled thermal management. Supports industrial automation, renewable energy, high-power inverter systems, EV charging stations, and rail transit.

Product Overview

The DZMJ series delivers capacitance of 1800 µF with water-cooled thermal management, supporting high-power DC filtering applications requiring efficient heat dissipation and long-term reliability.

The capacitor construction uses metallized polypropylene film dielectric with self-healing properties. High-purity aluminum foil electrode material combined with low ESR design significantly reduces energy loss and improves overall efficiency. High-temperature-resistant and corrosion-resistant insulating media ensure stable and reliable operation in different environments. The water-cooled design provides effective heat dissipation for high-power applications, maintaining stable operating temperature during continuous duty cycles.

Two configuration options are available to accommodate different system requirements: single cooled-isolated case design with sub-sections (all terminals isolated) and double cooled-isolated case design without sub-sections (all terminals isolated). The compact modular design facilitates installation and provides various wiring options for different installation scenarios.
