LGG2D821MELZ40

The LGG2D821MELZ40 is an aluminum electrolytic capacitor from Nichicon's LGG series, featuring a snap-in radial can termination and a compact footprint (φ22 × 40 mm). Designed for general-purpose applications, it delivers 820 µF capacitance at a 200 V rating with specifications optimized for compact equipment and high-ripple environments.

This part emphasizes a smaller case size within the LGG family, wide operating temperature capability, and endurance at elevated temperature for use in designs that require reliable bulk capacitance and robust ripple handling.

Key Features

• Capacitance & Voltage — 820 µF capacitance rated at 200 V for bulk energy storage and smoothing in general-purpose applications.
• Package & Mounting — Snap-in radial can (φ22 × 40 mm) for secure PCB mounting and compact board-level integration.
• Temperature & Endurance — Operating temperature range −40°C to 105°C with an endurance rating of 2000 hours at 105°C under rated conditions.
• Ripple Current Performance — Low-frequency ripple handling of 1.75 A (120 Hz) and high-frequency ripple handling of 2.625 A (100 kHz) to support demanding power circuits.
• Electrical Losses & Leakage — Dissipation factor (tan δ) specified at 0.15 (measured at 20°C, 120 Hz) and a measured leakage current of 1210 µA.
• Tolerance & Polarization — Capacitance tolerance ±20%; polarized component for correct polarity installation.
• Regulatory — RoHS compliant.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance for filtering and energy storage where a 200 V, 820 µF snap-in capacitor is required.
• Compact power supplies and converters — The LGG series is described as suited for equipment downsizing, offering a smaller case size within the family for space-constrained designs.
• Boards requiring snap-in mounting — Snap-in radial can termination for sturdy mechanical retention in assemblies that need through-hole bulk capacitors.
• High-ripple environments — Rated ripple currents at both low and high frequencies make this capacitor suitable where elevated ripple handling is necessary.

Unique Advantages

• Compact footprint: φ22 × 40 mm package offers bulk capacitance in a smaller case size, supporting equipment downsizing goals.
• High ripple capability: Specified ripple currents of 1.75 A (120 Hz) and 2.625 A (100 kHz) reduce thermal stress in power conversion and filtering applications.
• Wide operating range: −40°C to 105°C operation enables usage across a broad range of environmental conditions.
• Proven endurance at elevated temperature: 2000 hours at 105°C provides measurable assurance of long-term performance under rated conditions.
• Clear electrical specifications: Low tan δ (0.15 at 20°C, 120 Hz) and documented leakage current (1210 µA) allow precise design margin calculations.
• RoHS compliance: Meets environmental regulatory requirements for lead-free assemblies.
