LGR2W680MELA30

The LGR2W680MELA30 is a Nichicon LGR-series aluminum electrolytic capacitor in a snap‑in radial can package designed for general purpose applications requiring high voltage and long life at elevated temperature. It combines a 68 µF capacitance with a 450 V rated voltage and an operating temperature range to 105°C, delivering durable smoothing and energy-storage performance where sustained ripple endurance is required.

Engineered for extended operation, this part is specified to withstand applied rated ripple current under DC bias for 10,000 hours at 105°C and is RoHS compliant.

Key Features

• Electrical — High voltage: 68 µF nominal capacitance with a 450 V rated voltage for high‑voltage power rails.
• Temperature rating: Continuous operating range to 105°C (specified −25°C to 105°C for 400–450 V ratings), suitable for elevated‑temperature environments.
• Long life endurance: Long life assurance series: meets endurance test after 10,000 hours at 105°C with DC bias plus rated ripple current; capacitance change within ±25% and leakage not exceeding initial specified value.
• Ripple current capability: Rated ripple current of 530 mA at 120 Hz and 757.9 mA at 50 kHz for this part, with published frequency coefficients for the series to adjust allowable ripple versus frequency.
• Electrical reliability metrics: Leakage current specified by I ≤ 3√(C·V) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) max 0.20 at 450 V (measured at 120 Hz, 20°C).
• Mechanical & mounting: Snap‑in terminal, radial can package for secure PCB mounting in through‑hole assemblies.
• Tolerance and polarization: Capacitance tolerance ±20% (at 120 Hz, 20°C); polarized electrolytic capacitor.
• RoHS compliance: Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Power supply filtering: Use on high‑voltage DC rails where 450 V rating and elevated temperature endurance are required for smoothing and decoupling.
• Energy storage and bulk capacitance: Application in equipment needing compact bulk capacitance at high voltage with long operational life.
• Industrial power electronics: Suitable for general purpose industrial equipment requiring durable electrolytic capacitors in through‑hole assemblies.

Unique Advantages

• Extended high‑temperature life: Designed to withstand 10,000 hours of rated ripple current at 105°C, providing predictable long‑term performance under thermal stress.
• High voltage capability: 450 V rating enables use on higher DC buses without series stacking or derating strategies.
• Frequency‑aware ripple rating: Published frequency coefficients for the LGR series allow designers to scale allowable ripple current with operating frequency.
• Clear reliability limits: Endurance and shelf‑life criteria (capacitance, tan δ, leakage) are specified, making margin analysis and lifetime estimates straightforward.
• Robust mounting: Snap‑in radial can provides secure mechanical retention for through‑hole assemblies in industrial environments.
