LGR2G680MELZ30

The LGR2G680MELZ30 is a snap‑in terminal aluminum electrolytic capacitor rated 400 V with 68 µF capacitance. It belongs to Nichicon’s LGR long‑life series designed for prolonged operation at elevated temperatures and repeated ripple current loading.

Engineered for general‑purpose power applications, this polarized radial can offers long life assurance, robust ripple handling, and RoHS compliance for use in equipment requiring durable high‑voltage bulk capacitance.

Key Features

• Rated Performance — 68 µF capacitance at 400 V rating with ±20% tolerance (measured at 120 Hz, 20°C).
• Long Life Assurance — Designed for 10,000 hours endurance at 105°C with applied rated ripple current and DC bias; capacitance change within ±25% after endurance testing.
• High Temperature Range — Category operating temperature range for this part is −25°C to +105°C.
• Ripple Current Capability — Specified ripple current of 560 mA at 120 Hz and 800.8 mA at 50 kHz, with frequency coefficients provided in the series datasheet for higher frequency operation.
• Low Loss — Tangent of loss angle (tan δ) specified up to 0.15 for 200–400 V rated voltages (measurement at 120 Hz, 20°C).
• Leakage Current Spec — Leakage current defined by I ≤ 3√(C·V) (µA) after 5 minutes’ application of rated voltage at 20°C.
• Mounting & Package — Snap‑in terminal, radial can package (L: 3.0 cm × D: 2.2 cm) suitable for secure PCB mounting in power assemblies.
• RoHS Compliant — Meets RoHS directive requirements as noted in the product documentation.

Typical Applications

• General‑purpose power assemblies — Bulk smoothing and energy storage where a 400 V rated electrolytic capacitor with long life is required.
• High‑temperature environments — Use cases that demand sustained performance at elevated temperatures up to 105°C and guaranteed 10,000‑hour endurance.
• AC/DC and DC/DC power stages — Circuits that require high‑voltage ripple handling, leveraging the specified ripple current ratings at 120 Hz and 50 kHz.

Unique Advantages

• Durability under continuous load: 10,000 hours endurance at 105°C ensures predictable aging and stability for long‑running equipment.
• High voltage capability: 400 V rating provides headroom for high‑voltage power circuits without the need for series stacking of lower‑voltage capacitors.
• Engineered ripple handling: Explicit ripple current ratings at both low and high frequency help designers size bulk and filter capacitors with confidence.
• Clear electrical limits: Leakage current and tan δ specifications (I ≤ 3√CV; tan δ ≤ 0.15 at 400 V) enable accurate thermal and loss budgeting in designs.
• Secure snap‑in mounting: Radial snap‑in terminal package provides robust mechanical retention for power boards and assemblies.
• Regulatory compliance: RoHS conformity supports inclusion in products targeting global markets with restricted substances requirements.
