LLG2Z821MELA30

The LLG2Z821MELA30 is an aluminum electrolytic, snap‑in terminal capacitor from Nichicon’s LLG series. It delivers 820 µF at 180 V in a compact φ25 × 30 mm can, designed for general‑purpose power applications where high ripple handling and space savings are required.

Engineered for equipment downsizing and continuous operation up to 85°C, this RoHS‑compliant capacitor combines high low‑ and high‑frequency ripple capability with a 2000‑hour endurance rating at 85°C for reliable performance in production environments.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance rated for 180 V, suitable for bulk energy storage and smoothing in general‑purpose power circuits.
• High Ripple Current — Rated 2400 mA at 120 Hz (low frequency) and 3600 mA at 100 kHz (high frequency), supporting demanding ripple conditions.
• Endurance & Temperature — 2000 hours lifetime at 85°C with specified DC bias plus rated ripple current; operating temperature range −40°C to +85°C.
• Low Loss — Specified tangent of loss angle (tan δ) of 0.15 (max) at 20°C, 120 Hz, supporting stable AC performance.
• Leakage Current — Low leakage specified at 1150 µA, suitable for power circuits where minimized standby loss is important.
• Snap‑In, Radial Can Package — Snap‑in terminal mounting for secure mechanical retention and straightforward assembly in tray packing for mass production.
• Compact Size — φ25 × 30 mm (L: 30 mm, D: 25 mm) can size supports equipment downsizing; one rank smaller case size compared with the LLS series within the LLG family.
• RoHS Compliant — Manufactured to comply with applicable RoHS directives.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple suppression in general‑purpose power supplies where 180 V rating and high ripple capability are needed.
• Industrial power equipment — Energy storage and decoupling in compact industrial and commercial equipment benefiting from the smaller LLG case size.
• DC bus support — DC link and bus stabilization in systems requiring 820 µF at 180 V with reliable endurance at 85°C.

Unique Advantages

• High ripple handling: 2400 mA (120 Hz) and 3600 mA (100 kHz) ratings reduce thermal stress and extend service life under AC ripple conditions.
• Compact, snap‑in package: φ25 × 30 mm radial can with snap‑in terminals offers secure PCB retention and supports equipment downsizing.
• Verified endurance: 2000 hours at 85°C under rated bias and ripple—supports predictable lifetime planning for production designs.
• Low leakage and controlled dissipation: 1150 µA leakage and tan δ ≤ 0.15 at 20°C, 120 Hz enable efficient energy use and predictable AC loss performance.
• Production ready: Tray packing and mass production status simplify volume procurement and assembly integration.
• Regulatory compliance: RoHS compliance aligns with common environmental requirements for commercial and industrial products.
