LLG2E821MELC25

The LLG2E821MELC25 from Nichicon is an LLG-series aluminum electrolytic capacitor in a snap-in radial can package. It delivers 820 µF at a 250 V rating in a compact, one-rank-smaller case compared with the LLS series, making it suited for equipment downsizing and space-constrained designs.

Designed for general-purpose use, this polarized capacitor offers defined ripple-current capability and rated endurance for applications that require a compact high-capacitance, snap-in solution that is RoHS compliant.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 250 V rated voltage and ±20% tolerance (measured at 120 Hz, 20°C).
• Snap-In Radial Can Package — Snap-in terminals for secure PCB retention and ease of assembly in radial, can-style format.
• Compact Size for Downsizing — One rank smaller case than LLS and a physical size of L: 2.5 × D: 3.5 cm, enabling reduced footprint in assemblies.
• Operating Temperature & Endurance — Rated for operation from −40°C to +85°C with a specified endurance of 2000 hours at 85°C under DC bias plus rated ripple current.
• Defined Ripple Current Capability — 2.77 A at 120 Hz and 4.155 A at 100 kHz, suitable for designs that require known ripple-handling performance.
• Leakage and Dissipation Characteristics — Series datasheet specifies leakage current formula I ≤ 3√(CV) (μA) after 5 minutes at 20°C and tan δ limits applicable to rated voltages (tan δ max. 0.15 for 160–400 V at 120 Hz, 20°C).
• Polarized, General-Purpose Component — Intended for general-purpose electronic applications requiring a polarized electrolytic solution.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).
• Clear Marking — Product identification printed in white on a black sleeve for quick visual verification.

Typical Applications

• General-purpose electronic equipment — Provides bulk capacitance for a wide range of general-purpose circuits where a polarized electrolytic is required.
• Space-constrained power assemblies — Suited for designs focused on equipment downsizing due to its one-rank-smaller case size.
• PCB snap-in installations — Snap-in radial can package simplifies mechanical retention for through-hole assemblies.

Unique Advantages

• Compact, high-capacitance solution: 820 µF in a reduced case size enables higher capacitance without increasing board footprint.
• Reliable ripple handling: Specified ripple current at both low and high frequencies (2.77 A at 120 Hz; 4.155 A at 100 kHz) supports predictable performance in designs with AC components.
• Endurance under elevated temperature: 2000 hours at 85°C with DC bias plus rated ripple current provides a measurable reliability baseline for long-life applications.
• Design-friendly mounting: Snap-in terminals offer secure mechanical retention for through-hole PCB assemblies, aiding manufacturing robustness.
• Regulatory compliance: RoHS conformity supports use in markets requiring restricted-substance compliance.
• Easy identification: White-on-black sleeve marking assists assembly and maintenance workflows.
