LLG2E821MELB30

The LLG2E821MELB30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor sized φ30 × 30L (30 × 30 mm), rated at 820 µF and 250 V. It is a snap‑in, radial can design in the LLG series optimized for general‑purpose power applications and equipment downsizing.

Designed for production use and supplied in tray packing for mass production, this RoHS‑compliant capacitor delivers a combination of high capacitance, established endurance, and compact packaging for space‑constrained power designs.

Key Features

• Capacitance & Voltage — 820 µF capacitance at a 250 V rated voltage with a capacitance tolerance of ±20% (at 120 Hz, 20°C).
• Package & Mounting — Snap‑in terminal, radial can package (φ30 × 30 mm) suited for secure mechanical mounting in high‑density assemblies.
• Operating Temperature — Rated for operation from −40°C to +85°C, suitable for a wide range of commercial and industrial environments.
• Endurance — 2000 hours at 85°C under D.C. bias plus rated ripple current; capacitance, tan δ and leakage current meet datasheet endurance criteria after recovery to 20°C.
• Ripple Current Capability — Rated ripple current of 2.77 A at 120 Hz and 4.155 A at 100 kHz, supporting smoothing and filtering in power circuits across a range of frequencies.
• Leakage & Loss Characteristics — Leakage current specified per I ≤ 3√CV (µA) after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.15 for 160–400 V range.
• Regulatory — Compliant to RoHS directives as noted in the product documentation.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling in switching or linear power supplies where 250 V nominal ratings and high capacitance are required.
• Industrial Equipment — Energy storage and ripple management in industrial control and power conversion systems that require compact, durable capacitors.
• Commercial Electronics — General‑purpose energy storage and filtering in commercial systems where board space is constrained and production quantities are significant.

Unique Advantages

• Smaller-sized LLG series design — One rank smaller case size compared with the LLS series, enabling more compact equipment layouts without sacrificing capacitance.
• High ripple tolerance across frequencies — Specified ripple currents at 120 Hz and 100 kHz support performance in both low‑ and high‑frequency power circuits.
• Long endurance at elevated temperature — 2000 hours at 85°C under rated conditions provides predictable life characteristics for design planning.
• Robust snap‑in mounting — Snap‑in terminals and radial can construction facilitate reliable mechanical retention and consistent assembly in mass production.
• Manufacturing-friendly packaging — Supplied in tray packing for efficient handling and placement in production environments.
• Clear electrical specifications — Leakage current formula and tan δ limits provided for predictable behavior and verification in design validation.
