LGR2D821MELB40

The LGR2D821MELB40 is a snap-in terminal aluminum electrolytic capacitor engineered for long-life performance at elevated temperatures. It delivers 820 µF capacitance at a 200 V rating in a radial, can-type snap-in package suited for general-purpose electronic systems.

Designed for applications requiring sustained ripple endurance, this LGR-series part is specified to withstand 10,000 hours of rated ripple current at 105°C and is RoHS compliant.

Key Features

• Package & Termination — Radial, can-type snap-in mounting provides secure board attachment and straightforward PCB assembly for through-hole designs.
• Electrical Ratings — 820 µF capacitance at 200 V with capacitance tolerance of ±20% (120 Hz, 20°C).
• Temperature & Long Life — Operating temperature range of −40°C to +105°C and long-life assurance for 10,000 hours under rated ripple at 105°C.
• Ripple Current Capability — Rated ripple current of 2 A at 120 Hz and 3 A at 50 kHz; frequency coefficient data in the series supports increased allowable ripple at higher frequencies.
• Reliability Metrics — Endurance after 10,000 hours at 105°C: capacitance change within ±25%, tan δ up to 250% of initial specified value, and leakage current not exceeding initial specified value.
• Leakage Current Specification — Leakage current is specified as I ≤ 3√(C·V) µA after 5 minutes’ application of rated voltage at 20°C (C: µF, V: V).
• Regulatory Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy storage in systems where a 200 V, 820 µF capacitor with high ripple endurance is required.
• Industrial electronics — Use in assemblies operating up to 105°C that need long-duration reliability under continuous ripple stress.
• Power conversion modules — Suitable for circuits where radial snap-in mounting and robust ripple handling simplify design and maintenance.

Unique Advantages

• Proven long-life endurance: Specified 10,000 hours at 105°C under rated ripple current, enabling predictable lifecycle planning for high-temperature applications.
• High ripple tolerance: Defined ripple current ratings at common frequencies (2 A at 120 Hz, 3 A at 50 kHz) and frequency coefficients for higher-frequency operation reduce design uncertainty.
• Clear reliability criteria: Endurance and shelf-life limits (capacitance, tan δ, leakage current) are specified in the datasheet for confident qualification and testing.
• Robust thermal range: −40°C to +105°C operating range supports use across a wide set of environmental conditions where elevated ambient temperatures occur.
• RoHS compliant: Meets current RoHS requirements for regulatory consistency across international product deployments.
