LGG2C821MELZ35

The LGG2C821MELZ35 is an aluminum electrolytic capacitor from Nichicon’s LGG series featuring a snap-in radial can package and an 820 µF capacitance at 160 V. It targets general-purpose power applications that require compact energy storage with robust ripple handling and high-temperature endurance.

Designed as an ultracompact snap-in solution (one rank smaller case than LGN), this part supports equipment downsizing while delivering specified ripple current capability and long-term stability up to 105 °C. The device is RoHS compliant and available in tray packing for mass production.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a rated voltage of 160 V and ±20% tolerance (measured at 120 Hz, 20 °C).
• High-Temperature Endurance — Rated for 2000 hours at 105 °C under D.C. bias plus rated ripple current, meeting the LGG series endurance definition for capacitance, tan δ and leakage current recovery.
• Ripple Current Performance — Rated ripple current of 2.0 A at 120 Hz (low frequency) and 3.0 A at 100 kHz (high frequency), enabling effective smoothing and decoupling under varying ripple profiles.
• Leakage Current — Specified leakage current of 1,080 µA, with series guidance I ≤ 3√CV (μA) after 5 minutes’ application of rated voltage at 20 °C.
• Operating Temperature Range — −40 °C to +105 °C to support elevated-temperature system environments.
• Compact Snap-In Package — φ22 × 35 mm (D × L) radial can, snap-in terminals for secure PCB mounting and mechanical stability in power assemblies.
• Loss Angle (tan δ) — Series maximum tan δ of 0.15 for rated voltages 160 to 420 V (measured at 120 Hz, 20 °C), consistent with LGG series electrical characteristics.
• Regulatory — Compliant with RoHS (2011/65/EU,(EU)2015/863).

Typical Applications

• Industrial power systems: Bulk smoothing and energy storage in power supplies and converters where 160 V rated systems require robust ripple handling and high-temperature endurance.
• Power electronics assemblies: Filtering and decoupling for inverter or drive circuits that benefit from high ripple current capability and compact snap-in mounting.
• Equipment requiring compact high-voltage capacitors: Designs targeting reduced footprint or equipment downsizing that need an 820 µF, 160 V solution in a smaller case size.

Unique Advantages

• Space-saving form factor: One rank smaller case size than the LGN series and a φ22 × 35 mm footprint help reduce chassis and PCB real estate.
• Robust ripple capacity across frequencies: Dual-specified ripple ratings (2.0 A at 120 Hz and 3.0 A at 100 kHz) address both low- and high-frequency ripple environments.
• High-temperature reliability: 2000-hour endurance at 105 °C with defined post-test limits for capacitance, tan δ and leakage current supports extended service life in hot environments.
• Low leakage behavior: Specified leakage current of 1,080 µA and series guidance for initial leakage help maintain efficiency and predictable bias performance.
• Snap-in radial construction: Secure mechanical mounting and straightforward assembly for power modules and board-level installations.
• RoHS compliance: Meets RoHS directive requirements for environmental regulatory adherence.
