LGG2D821MELB25

The LGG2D821MELB25 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGG series. It provides 820 µF capacitance at a 200 V rating in a compact, radial snap‑in can (φ30 × 25 mm) designed for equipment downsizing and reliable power handling.

Engineered for general‑purpose power applications, this component combines high ripple capability, a wide operating temperature range (‑40 °C to +105 °C) and a 2000‑hour endurance at 105 °C to support robust designs that require stable bulk capacitance and load smoothing.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance with a 200 V rated voltage and ±20% tolerance (at 120 Hz, 20 °C) for bulk energy storage and smoothing.
• Compact Snap‑In Package — Radial, snap‑in can in φ30 × 25 mm (L: 2.5 cm × D: 3.0 cm) that supports equipment downsizing; specified as an ultra‑smaller‑sized 105 °C series.
• High Temperature Endurance — Rated for operation from ‑40 °C to +105 °C with a specified endurance of 2000 hours at 105 °C under DC bias plus rated ripple current.
• Ripple Current Performance — Low‑frequency ripple current 1.75 A (120 Hz) and high‑frequency ripple current 2.625 A (100 kHz), supporting demanding AC superposition and switching environments.
• Electrical Loss & Leakage — Tangent of loss angle (tan δ) max 0.15 (measured at 20 °C, 120 Hz) and specified leakage current of 1210 µA for predictable dissipation and standby characteristics.
• Compliance & Production — RoHS compliant and available in tray packing; part is in mass production for volume designs.

Typical Applications

• Power supply filtering — Bulk smoothing and energy storage in AC‑DC and DC‑DC supplies where 200 V rating and high ripple capability are required.
• Industrial power electronics — DC link and intermediate bus decoupling in equipment that must tolerate elevated operating temperatures up to 105 °C.
• Equipment downsizing projects — Use in designs targeting reduced enclosure size where the LGG series' ultra‑smaller case helps minimize PCB footprint.

Unique Advantages

• High ripple tolerance: Specified ripple currents at both 120 Hz and 100 kHz enable use with low‑ and high‑frequency switching environments without overspecifying components.
• Compact, snap‑in form factor: φ30 × 25 mm radial snap‑in can supports space‑conscious layouts and secure mechanical mounting.
• Wide temperature range with proven endurance: Rated for ‑40 °C to +105 °C and validated for 2000 hours at 105 °C for reliable long‑term operation under thermal stress.
• Predictable electrical behavior: Low tan δ (0.15 max at 20 °C, 120 Hz) and defined leakage current provide consistent loss and standby characteristics for thermal and power budgeting.
• RoHS compliant and production ready: Environmentally compliant construction and tray packing facilitate integration into production lines.
