Details

Electronic Concepts DC-Link Film Capacitors serve as an intermediary DC smoothing stage between AC stages. This intermediate DC step facilitates noise-reduced power transfer when converting between AC sources with varying power, frequency, or voltage conditions. These capacitors frequently endure high slew rates, necessitating the selection of robust components to ensure reliability. They are commonly found in power inverters, high-power charging circuits, and motor drives. In DC-link applications, different capacitor technologies may be combined to effectively target transients and noise, requiring multiple stages of filtering.

Electronic Concepts’ DC-Link Film Capacitors are optimized for DC power conversion and are widely used in UPS systems, wind and solar inverters, and traction and industrial drives. Their case sizes are suitable for any application requiring DC linkage.

Benefits:

• Self-Healing, Self-Protecting
• Long Life, Highly Reliable
• Low Loss, Low ESR
• Flame Retardant

Explore the range of Electronic Concepts DC-Link Film Capacitors, which include capacitors with UNLYTIC® film technology. Notably, the UL30 film capacitor is the first film dielectric capacitor replacement for electrolytic capacitors.

UL3 Capacitor Series: Low Inductance with High Current Carrying Capability

The UL3 Capacitor Series features low inductance and high current carrying capability, along with a low profile design to maximize system space and cooling efficiency. Its enclosure is made with an in-house developed thermoplastic formulation that improves thermal conductivity.

The series also includes an integrated flange with pre-drilled holes for easy mounting.

The introduction of the UNLYTIC® UL3 SERIES provides designers with a high-power film capacitor for filter systems that optimizes space utilization, performance, and reliability, while offering potential production cost savings.

UP3 Capacitor Series: Cost-Effective Packaging

The UP3 Capacitor Series enhances the existing UL30 product offering by incorporating UNLYTIC® film technology with cost-effective packaging. This design provides higher storage capacity and voltage creepage protection. The solid plastic top creates a gap of more than one inch between the case and terminal connections, isolating the capacitor from the outer case for easy mounting. This series is ideal for bulk DC storage, particularly in DC link converter/inverter applications.

MP3 Capacitor Series: Cost-Effective Packaging

The MP3 Capacitor Series builds on the UL3 product offering, integrating UNLYTIC® film technology with new cost-effective packaging. This design enhances storage capacity and voltage creepage protection, while isolating the capacitor from the outer case for easy mounting. The MP3 series is well-suited for bulk DC storage, especially in DC link converter/inverter applications.

UL9 Capacitor Series: Optimized for DC Power Conversion

The UL9 Capacitor Series utilizes proven UNLYTIC® technology to significantly reduce weight and size, optimizing it for DC power conversion. It also incorporates traditional dry film “self-healing” properties, ensuring long life and reliability.

UH3 Capacitor Series: Low Inductance & High Current Carrying Capability

The UH3 Capacitor Series features low inductance and high current carrying capability. It operates up to +125°C and can withstand hostile environments.

UP2 Capacitor Series: High Capacitance, Simple Design

The UP2 Capacitor Series includes Unlytic polypropylene in an oval polyester wrap with epoxy end fill. Its terminals are RoHS compliant, tin-plated copper.

UL30 Capacitor Series: Available in Values & Sizes Previously Achieved Only by Electrolytics

The UL30 Capacitor Series offers superior performance characteristics of film capacitors in values and sizes previously only achievable by electrolytics. This advancement improves high power system design by enhancing reliability, extending service life, enabling miniaturization, reducing production costs, and maximizing performance.

The UNLYTIC® UL30 series has packaging dimensions identical to electrolytics, allowing for direct replacement without requiring conceptual changes in system design.
