LLG2E821MELA40

The LLG2E821MELA40 is an aluminum electrolytic, snap-in terminal capacitor from Nichicon's LLG series. It provides 820 µF of capacitance at a 250 V rating in a compact, snap-in radial can designed to support equipment downsizing.

Built for general-purpose use, this component delivers high ripple current capability, defined leakage and loss characteristics, and a 2,000 hour endurance at 85°C—making it suitable for PCB-mounted power assemblies and compact electronic equipment.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 250 V for bulk energy storage and smoothing in general-purpose circuits.
• Snap-in Radial Can Package — Snap-in mounting simplifies PCB assembly for radial, snap-in configurations; package size φ25 × 40 mm supports compact layouts and equipment downsizing (one rank smaller than LLS).
• Ripple Current Performance — Low-frequency ripple current 2.77 A (120 Hz) and high-frequency ripple current 4.155 A (100 kHz) to handle varying operating conditions.
• Loss and Leakage — Tangent of loss angle (tanδ) max 0.15 measured at 20°C, 120 Hz; specified leakage current 1,350 µA.
• Temperature and Endurance — Operating range –40°C to +85°C with rated endurance of 2,000 hours at 85°C under DC bias plus rated ripple current; post-test limits include capacitance within ±20%, tanδ ≤ 200% of initial, and leakage ≤ initial specified value.
• Compliance & Packaging — RoHS compliant; supplied in tray packing and available in mass production status.
• Clear Identification — Marked with white lettering on a black sleeve for polarity and part identification.

Typical Applications

• General-purpose electronic equipment — For circuits requiring 820 µF at 250 V where a snap-in electrolytic capacitor is appropriate.
• Compact PCB-mounted assemblies — Snap-in radial can and smaller case size support tighter layouts and equipment downsizing.
• Power filtering and smoothing — Provides bulk capacitance and ripple handling for power supply assemblies within the specified temperature and endurance limits.
• Production and service-ready builds — Tray packing and mass production status facilitate volume assembly and replacement use.

Unique Advantages

• Space-efficient form factor: One-rank smaller case than LLS with φ25 × 40 mm dimensions, helping reduce enclosure and board footprint.
• High ripple capability across frequencies: Rated ripple currents of 2.77 A (120 Hz) and 4.155 A (100 kHz) support both low- and high-frequency ripple conditions.
• Defined electrical stability: Low tanδ (max 0.15 at 20°C, 120 Hz) and specified leakage current allow predictable circuit behavior.
• Endurance at elevated temperature: Designed to meet performance criteria after 2,000 hours at 85°C under rated bias and ripple, with defined recovery limits for capacitance, tanδ, and leakage.
• Manufacturing readiness: RoHS compliance and tray packing combined with mass-production availability support scalable procurement and assembly.
• Easy identification: White-on-black sleeve marking provides clear polarity and part identification during assembly and maintenance.
