LGN2C821MELB25

The LGN2C821MELB25 is a 820 µF, 160 V aluminum electrolytic capacitor in a radial can with snap-in terminals. It is a smaller-sized, snap-in terminal type designed for general-purpose applications that require elevated temperature endurance and reliable ripple-current handling.

Rated for operation from −40 °C to +105 °C and compliant with RoHS (2011/65/EU, (EU)2015/863), this part is specified to withstand 3000 hours of rated ripple current at 105 °C and offers a compact footprint for space-constrained power designs.

Key Features

• Electrical Performance — 820 µF capacitance at a 160 V rated voltage with a tolerance of −20% to +20%.
• High-Temperature Endurance — Specified endurance of 3000 hours when D.C. bias plus rated ripple current is applied at 105 °C.
• Ripple Current Capability — Rated ripple current: 2 A at 120 Hz and 3 A at 100 kHz, suitable for continuous ripple handling in power circuits.
• Package and Mounting — Snap-in terminal, radial can package designed for secure board retention and straightforward assembly.
• Compact Size — Smaller-sized case compared with the LGU series; physical dimensions: L: 2.5 × D: 3 cm with a maximum seated height of 2.5 cm.
• Temperature Range — Operating temperature from −40 °C to +105 °C, supporting elevated-temperature system environments.
• Leakage and Loss Characteristics — Datasheet limits leakage current to I ≤ 3√C µA after 5 minutes at 20 °C; tan δ (loss angle) max. 0.15 for 160–420 V parts (measurement at 120 Hz, 20 °C).
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863) requirements.

Typical Applications

• General-purpose power supplies — Bulk capacitance and rated ripple current make this capacitor suitable for smoothing and energy storage in power supply rails.
• Industrial control electronics — Designed for elevated-temperature endurance (3000 hours at 105 °C) where stable capacitance over time is required.
• Power conversion and DC link circuits — High ripple capability at both low and high frequencies supports use in converter and inverter DC link stages.

Unique Advantages

• Proven high-temperature endurance: 3000-hour rating at 105 °C provides a quantified reliability metric for designs operating in hot environments.
• Compact, snap-in form factor: One rank smaller case than LGU and a radial snap-in can simplify layout in space-constrained boards while ensuring robust board retention.
• Dual-frequency ripple handling: Specified ripple current at 120 Hz and 100 kHz (2 A and 3 A respectively) lets designers assess performance across common power frequencies.
• Measurable leakage and loss limits: Defined leakage current and tan δ limits enable predictable performance and easier qualification during design validation.
• RoHS compliance: Meets applicable environmental directives for lead-free assemblies.
