LGN2P821MELB35

The LGN2P821MELB35 is a Nichicon aluminum electrolytic capacitor in a snap-in radial can designed for general-purpose applications. It delivers 820 µF at a 220 V rating with polarized construction and is intended for designs that require sustained high-temperature operation and long ripple-endurance.

Key architecture details include a snap-in terminal mounting in a compact can (L: 3.5 × D: 3 cm) and proven endurance: the part withstands 3000 hours of rated ripple-current application at 105°C. It is RoHS compliant.

Key Features

• Capacitance & Voltage: 820 µF nominal capacitance with a 220 V rated voltage suitable for bulk energy storage and DC filtering in general-purpose power circuits.
• High-temperature endurance: Specified operating temperature range of −40 °C to +105 °C and rated to withstand 3000 hours of rated ripple current at 105 °C.
• Ripple current performance: Rated ripple current of 1.93 A at 120 Hz and 2.895 A at 100 kHz, supporting continuous filtering under AC ripple stress.
• Compact snap-in package: Radial snap-in can package with dimensions L: 3.5 × D: 3 cm and a maximum seated height of 1.378 inch, offering a one-rank smaller case size than the LGU series.
• Polarized with standard tolerance: Polarized capacitor with capacitance tolerance of −20% to +20% (±20% at 120 Hz, 20 °C).
• Lifecycle and stability: Endurance specification ensures capacitance change within ±20%, tan δ within 200% of initial, and leakage current not exceeding initial specified value after the 3000-hour endurance test at 105 °C.
• Environmental compliance: Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering: Bulk energy storage and ripple smoothing in general-purpose power supplies operating up to 105 °C, leveraging the part's rated ripple-current endurance.
• DC link / bulk capacitance: Use as a bulk capacitor for converters and power electronics where high ripple handling and long-term stability at elevated temperature are required.
• General-purpose power electronics: Suitable for a range of general-purpose circuits that require reliable polarized aluminum electrolytic capacitance in a compact snap-in package.

Unique Advantages

• Long high-temperature service life: Engineered to withstand 3000 hours of rated ripple current at 105 °C, providing predictable endurance for elevated-temperature applications.
• High ripple capability: Specified ripple ratings at both low and high frequencies (1.93 A at 120 Hz and 2.895 A at 100 kHz) help reduce thermal stress and improve reliability under AC load.
• Space-efficient form factor: One rank smaller case size than the LGU series and compact dimensions (3.5 × 3 cm) allow more efficient board layout and denser power assemblies.
• Clear electrical specification: 820 µF at 220 V with ±20% tolerance and polarized construction makes selection and substitution straightforward for design engineers.
• Standards-aligned endurance metrics: Endurance and shelf-life criteria from the datasheet provide measurable, verifiable limits for capacitance change, tan δ, and leakage after stress and storage.
• RoHS compliant: Conforms to current RoHS requirements for restricted substances, simplifying regulatory considerations.
