Product Description

Overview of High-Ripple Electrolytic Capacitors

Our high-ripple electrolytic capacitors are engineered specifically for switching power supply applications, delivering consistent performance in demanding industrial environments. With a standard 3000-hour high ripple current rating and 105°C operating temperature capability, these snap-in capacitors provide the stability required for continuous commercial operations. Available in voltage ratings from 50V to 700V and capacitance values from 47μF to 47000μF, our product line accommodates a wide range of switching power supply designs.

Key Features of High-Ripple Electrolytic Capacitors

Temperature and Durability Performance

These capacitors operate within a temperature range of -40°C to +105°C for voltage ratings from 16V to 250V, and -25°C to +105°C for voltage ratings from 315V to 450V. Under rated voltage and standard ripple current conditions at 105°C, the capacitors maintain performance for 3000 hours. After this endurance test, capacitance change remains within ±20% of the initial value, dissipation factor (tan δ) does not exceed 150% of the initial standard, and leakage current stays within initial specifications.

Electrical Characteristics

The capacitors feature a rated capacitance tolerance of ±20% at 120Hz and 20°C. Leakage current is limited to the smaller value of 3/CV (μA) or 5mA when measured at 20°C after 5 minutes of voltage application. Dissipation factor values vary by voltage rating, ranging from 0.45 at 16V to 0.15 at 160-420V, and 0.20 at 450V. Frequency correction factors are provided for accurate performance calculation across different operating frequencies.

Compliance and Safety Standards

All our high-ripple electrolytic capacitors comply with RoHS directives and have passed CE and CB testing certifications, meeting EU safety and environmental requirements. This ensures compatibility with global commercial procurement standards and reduces compliance risks for our customers.
