LLG2W471MELC35

The LLG2W471MELC35 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LLG series. It delivers 470 µF capacitance at a 450 V rating in a compact snap‑in radial can designed for space‑sensitive, high‑voltage applications.

Designed for general‑purpose use and suited for equipment downsizing, this part offers high ripple handling, a 2000‑hour endurance at 85°C, and RoHS compliance for modern production requirements.

Key Features

• Electrical Performance — 470 µF capacitance with a rated voltage of 450 V and ±20% tolerance, providing bulk energy storage for high‑voltage rails.
• Low Loss — Tangent of loss angle (tan δ) up to 0.20 measured at 20°C, 120 Hz, for predictable dissipation characteristics.
• High Ripple Current — Rated ripple current of 2.32 A at 120 Hz (low frequency) and 3.318 A at 100 kHz (high frequency) to support ripple smoothing and transient load conditions.
• Leakage Current — Specified leakage current of 1,370 µA, defined per the product datasheet conditions after voltage application.
• Reliability / Endurance — 2000 hours life rating at 85°C with DC bias plus rated ripple current; meets the listed endurance characteristics after recovery to 20°C.
• Operating Range — Rated for operation from −25°C to +85°C (per the 400–450 V category in the datasheet), suitable for a range of environmental conditions.
• Mechanical / Mounting — Snap‑in terminal, radial can package (φ35 × 35L, 3.5 × 3.5 cm), enabling secure PCB mounting for panel and chassis assemblies.
• Compliance — RoHS compliant for regulatory alignment in production environments.

Typical Applications

• High‑voltage power supplies — Bulk smoothing and energy storage on DC rails up to 450 V where compact, high‑voltage capacitors are required.
• Industrial power equipment — Filtering and ripple suppression in industrial converters and control systems operating within −25°C to +85°C.
• Space‑sensitive equipment — Equipment downsizing applications that benefit from the LLG series’ smaller case size compared with larger LLS cases.

Unique Advantages

• High‑voltage capability: 450 V rating enables use on high‑voltage rails without series stacking.
• Compact snap‑in form factor: φ35 × 35L radial can with snap‑in terminals supports secure mounting while saving PCB footprint.
• Robust ripple handling: 2.32 A (120 Hz) and 3.318 A (100 kHz) ripple ratings help improve ripple suppression and thermal performance under load.
• Long endurance at elevated temperature: 2000 hours at 85°C under rated conditions provides predictable lifecycle behavior for sustained operation.
• Defined loss characteristics: tan δ ≤ 0.20 at 120 Hz, 20°C gives predictable dissipation for thermal and stability planning.
• Regulatory readiness: RoHS compliance supports modern manufacturing and environmental requirements.
