LGR2D821MELC30

The LGR2D821MELC30 is an aluminum electrolytic capacitor in Nichicon’s LGR long-life snap-in series. It delivers 820 µF at 200 V in a radial, can-type snap‑in package designed for general-purpose applications.

Engineered for elevated-temperature endurance, this part is specified for operation from –40 °C to 105 °C and is rated to withstand 10,000 hours of DC bias plus rated ripple current at 105 °C, making it suitable where sustained high-temperature ripple performance and long service life are required.

Key Features

• Capacitance & Voltage — 820 µF nominal capacitance at a rated voltage of 200 V with capacitance tolerance of ±20% (–20% ~ 20%).
• Long‑Life Endurance — Endurance rating: meets the series specification after 10,000 hours at 105 °C with DC bias plus rated ripple current; capacitance change within ±25%, tan δ ≤ 250% of initial, leakage current ≤ initial specified value.
• Extended Temperature Range — Operational temperature range from –40 °C to 105 °C for stable performance across broad thermal environments.
• Ripple Current Capability — Rated ripple current: 2 A at 120 Hz (low frequency) and 3 A at 50 kHz (high frequency); series frequency coefficient shows increased allowable ripple at higher frequencies (for 200/250 V, coefficient up to 1.50 at ≥50 kHz).
• Package & Mounting — Radial can with snap‑in terminals for secure panel or chassis mounting and robust mechanical retention.
• Leakage & Dissipation — Leakage current specified by the series formula I ≤ 3√(C·V) μA (measured after 5 minutes at 20 °C); tangent of loss angle (tan δ) max. 0.15 for 200–400 V ratings (measured at 120 Hz, 20 °C).
• Regulatory Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power circuits — Provides bulk capacitance where a 200 V, 820 µF aluminum electrolytic with long-life characteristics is required.
• High-ripple environments — Suitable for circuits that must handle sustained ripple currents up to 3 A at high frequency (50 kHz) and 2 A at 120 Hz.
• Elevated-temperature systems — Intended for designs that require reliable operation across –40 °C to 105 °C and validated endurance after 10,000 hours at 105 °C.

Unique Advantages

• Verified long-life performance: 10,000-hour endurance at 105 °C under DC bias plus rated ripple current gives predictable aging characteristics for maintenance planning.
• High-frequency ripple support: Rated ripple currents and series frequency coefficients enable higher allowable ripple at elevated frequencies, improving design flexibility for switching supplies.
• Snap‑in mechanical retention: Radial, can-style snap-in terminals provide secure mounting for board or chassis installations where robust mechanical support is needed.
• Clear electrical limits: Leakage current defined by I ≤ 3√(C·V) and tan δ limits are specified, allowing straightforward verification against design requirements.
• Wide operating temperature: –40 °C to 105 °C rating supports deployment across a broad range of thermal conditions while maintaining specified performance.
• RoHS compliant: Conforms to applicable RoHS directives, satisfying environmental material requirements.
