LGN2D821MELA35

The LGN2D821MELA35 is an aluminum electrolytic capacitor in a snap-in terminal radial can, engineered for general-purpose electronic applications. It provides 820 µF capacitance at a 200 V rating with polarized construction and a compact, one-rank-smaller case than the LGU series.

Designed for sustained operation in elevated temperatures, this part withstands 3,000 hours of rated ripple current at 105°C and is RoHS compliant, making it suitable for designs that require long-term high-temperature endurance and secure snap-in mounting.

Key Features

• Capacitance & Voltage — 820 µF rated capacitance at 200 V with ±20% tolerance, suitable where this specific capacitance/voltage point is required.
• High‑Temperature Endurance — Specified to withstand 3,000 hours of rated ripple current at 105°C; endurance recovery criteria include capacitance change within ±20% and leakage current no greater than initial specified values after test.
• Ripple Current Capability — Rated ripple currents of 2.04 A at 120 Hz and 3.06 A at 100 kHz, enabling continuous AC ripple handling at common frequencies.
• Package & Mounting — Snap‑in terminal, radial can package for secure PCB installation and mechanical retention.
• Compact Size — One rank smaller case than LGU; physical size L: 3.5 × D: 2.5 cm with a maximum seated height of 1.378 inch, offering a reduced footprint for space‑constrained layouts.
• Operating Temperature Range — Rated for −40 °C to +105 °C operation, matching the high-temperature endurance specification.
• Polarized Electrolytic — Polarized design for DC applications requiring electrolytic capacitance.
• RoHS Compliant — Conforms to RoHS requirements (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic circuits — Suited for designs that require a 820 µF, 200 V polarized capacitor in a snap-in radial can.
• High-temperature assemblies — For equipment operating up to 105 °C where long-duration ripple endurance is needed.
• Secure PCB mounting — Snap-in terminals provide mechanical retention for vertical radial installation in assemblies demanding robust mounting.

Unique Advantages

• Proven high-temperature endurance — Rated to sustain 3,000 hours of rated ripple current at 105 °C, supporting longevity in thermally demanding environments.
• High ripple-handling — Explicit ripple current ratings at both low and high frequencies (120 Hz and 100 kHz) allow designers to evaluate AC stress performance against application needs.
• Space-efficient footprint — One rank smaller case than the LGU series provides a compact alternative for designs constrained by board area or height.
• Secure snap-in mounting — Radial, snap-in can design simplifies PCB retention and mechanical stability for through‑hole assemblies.
• Clear specification baseline — Manufacturer endurance and shelf‑life criteria (capacitance tolerance, tan δ limits, and leakage current recovery) give predictable behavior after high-temperature and long-term stress.
• Regulatory compliance — RoHS conformity supports use in designs requiring restricted substance compliance.
