Key Features

• Dielectric / Construction Conductive polymer aluminum solid electrolytic construction with polarized radial-lead terminals for through-hole mounting.
• Capacitance & Voltage 820 µF nominal capacitance with tolerance −20% to +20% at a 25 V rated voltage.
• Low ESR ESR of 10 mΩ measured at 20 °C / 100 kHz, enabling reduced power losses in high-frequency circuits.
• High Ripple Current Rated ripple current of 810 mA at 120 Hz and 8.1 A at 300 kHz, supporting both low- and high-frequency power filtering.
• Temperature & Endurance Operating range −55 °C to +105 °C with a load life specification of 5000 hours at 105 °C.
• Size & Mounting Compact φ10 × 20 mm can, radial lead spacing 5.0 mm (±0.5 mm) and lead diameter 0.6 mm; available in bulk or bag packing.
• Leakage & Dissipation Leakage current specified at 2050 µA (after 2 minutes at 20 °C) and tan δ of 0.12 at 20 °C / 120 Hz.
• Compliance & Availability RoHS compliant and listed as mass production status.

Typical Applications

• Power supply filtering — Bulk smoothing and hold-up in general-purpose DC power supplies where high capacitance and low ESR reduce ripple and losses.
• High-frequency power circuits — Decoupling and ripple management in circuits operating at 100 kHz–300 kHz, leveraging the 8.1 A ripple rating at 300 kHz.
• Industrial electronics — Energy buffering and transient suppression in equipment that requires wide temperature operation and long life at elevated temperatures.

Unique Advantages

• Low conduction losses: 10 mΩ ESR at 100 kHz minimizes I²R losses and thermal stress in high-current loops.
• High ripple handling: 8.1 A ripple current capability at high frequency supports demanding switching-power and DC-DC converter environments.
• Long-term thermal endurance: 5000 hours at 105 °C provides predictable life in elevated-temperature applications.
• Compact high capacitance: 820 µF in a φ10×20 mm can saves board space while delivering substantial bulk capacitance.
• Robust operating range: −55 °C to +105 °C covers a broad set of industrial and electronic environments.
• Production-ready and compliant: RoHS-compliant construction and mass-production availability simplify sourcing and integration.
