Key Features

• Conductive polymer hybrid construction Combines conductive polymer properties with aluminum electrolytic technology to provide low ESR and stable ripple performance.
• Capacitance & tolerance 330 µF nominal capacitance with a tolerance of −20% to +20% at 120 Hz, 20°C, suitable for bulk decoupling and energy storage in compact footprints.
• Rated voltage 25 V rated voltage for medium-voltage power stages and supply rails.
• Low ESR ESR specified at 20 mΩ (20°C, 100 kHz), supporting efficient high-frequency decoupling and reduced power loss.
• High ripple current capability Low-frequency ripple current 300 mA (120 Hz) and high-frequency ripple current 2.0 A (100 kHz), enabling robust handling of both low- and high-frequency ripple components.
• Leakage current Typical leakage current 82.5 µA (0.01CV after 2 minutes at 20°C), supporting predictable standby and held-charge behavior.
• Extended endurance at high temperature Life rating of 4000 hours at 135°C under rated conditions, designed for long-term operation in hot environments.
• Wide operating temperature range −55°C to +135°C for deployment across harsh thermal environments.
• Automotive-grade qualification AEC-Q200 rating, indicating suitability for designs requiring automotive reliability standards.
• Surface-mount, vibration-resistant can φ10 × 10 mm can-style SMD package with vibration resistance and embossed carrier taping for automated assembly; recommended land size 10.3 × 10.3 mm.
• RoHS compliant Meets RoHS requirements for restricted substances.

Typical Applications

• Automotive electronics For power modules and supply rails in automotive systems that require AEC-Q200-qualified capacitors with high-temperature endurance.
• High-temperature electronics Systems operating across −55°C to +135°C that need components rated for extended life at elevated temperatures.
• Power-stage decoupling and filtering Bulk energy buffering and ripple suppression where low ESR and multi-frequency ripple handling (120 Hz and 100 kHz) improve power integrity.

Unique Advantages

• Low ESR for efficient filtering: 20 mΩ ESR at 100 kHz reduces losses and improves high-frequency decoupling performance.
• Dual-frequency ripple capability: Specified ripple handling at both 120 Hz and 100 kHz (300 mA / 2.0 A) supports mixed-frequency power systems.
• High-temperature endurance: 4000 hours at 135°C enables longer service life in thermally demanding designs.
• Automotive-grade reliability: AEC-Q200 qualification aligns the part with automotive system requirements for robustness.
• Surface-mount can package with tape-and-reel: φ10 × 10 mm SMD can, vibration resistant and packaged in embossed carrier taping for automated assembly.
• Predictable leakage behavior: 82.5 µA leakage (0.01CV) gives designers a clear basis for standby and hold-up calculations.
