Engineered for high ripple handling and ultra low ESR, this radial lead capacitor supports demanding thermal and ripple environments with a rated operating temperature range of −55°C to +105°C and a load life specification of 2000 / 5000 hours at 105°C.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 2.5 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Ultra Low ESR — Equivalent series resistance of 7 mΩ measured at 100 kHz, 20°C for reduced losses and improved power efficiency.
• High Ripple Current Capability — Rated ripple current of 560 mA at 120 Hz and 5.6 A at 300 kHz, enabling robust AC ripple absorption in power circuits.
• Wide Temperature & Endurance — Operates from −55°C to +105°C with an endurance (load life) test condition of 2000 / 5000 hours at 105°C and rated voltage.
• Radial Lead Packaging — Compact radial can with 3.5 mm lead spacing and dimensions L: 11.5 mm × D: 8 mm (1.15 × 0.8 cm), suitable for through-hole mounting and flow soldering processes.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863) and supports lead-free flow soldering conditions.

Typical Applications

• General-purpose power filtering — Use where high ripple current and low ESR are required to smooth supply lines and reduce voltage ripple in compact power stages.
• DC–DC converter output filtering — Compact radial form factor and high-frequency ripple capability make it suitable for output capacitors in regulated power modules.
• Embedded and industrial electronics — Reliable operation across −55°C to +105°C and extended load life for general-purpose circuit functions in a wide range of electronic products.

Unique Advantages

• Low-loss performance: 7 mΩ ESR at 100 kHz minimizes conduction losses and heat generation in high-frequency applications.
• High ripple tolerance: Up to 5.6 A at 300 kHz supports aggressive ripple currents found in modern power conversion circuits.
• Compact, board-friendly package: 8×11.5 mm can with 3.5 mm lead spacing offers high capacitance in a small through-hole footprint.
• Robust thermal endurance: Rated for −55°C to +105°C and specified for 2000 / 5000 hours at 105°C, helping maintain capacitance and ESR stability over time.
• Compliance and process compatibility: RoHS compliant and compatible with lead-free flow soldering conditions for modern manufacturing lines.
