Type BLS Capacitors Offer A Reliable Solution For High Humidity Environments

The Type BLS 125°C DC Link Capacitors are engineered to deliver outstanding reliability and long service life, making them particularly well-suited for demanding applications in alternative energy systems and electric vehicles. Designed to withstand harsh operating environments where exposure to temperature fluctuations and moisture is constant, these capacitors provide dependable performance where it matters most.

Demonstrating exceptional durability, the Type BLS series has successfully passed rigorous 2,000-hour temperature-humidity bias (THB) testing at 85°C and 85% relative humidity, far exceeding typical requirements. Meeting automotive-grade AEC-Q200 standards, these capacitors deliver twice the rated lifetime at rated voltage compared to many competing solutions, ensuring superior operational stability.

Key design features include a wide operating temperature range of -55°C to 125°C, making them an ideal match for high-speed SiC semiconductor switching environments. They are offered with capacitance values ranging from 1 µF to 220 µF and voltage ratings between 450 and 1100 Vdc, providing flexibility across a range of power conversion and filtering applications.

The robust construction features UL94-V0 flame-retardant plastic encapsulation with thermosetting resin potting, which enhances resistance to solvents, vibration, and mechanical stress. Additionally, flexible mounting options are available, supporting both horizontal and vertical board mounting with 2- or 4-pin configurations to meet varying design needs.

Ideal for DC filtering and DC link circuits, the Type BLS capacitors combine high performance with proven reliability. Whether in renewable energy infrastructure or electric vehicle platforms, they provide consistent, long-term performance under challenging environmental conditions.
