LNR1E684MSE

The LNR1E684MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNR series, offering 680,000 µF (680 mF) nominal capacitance at 25 V with a ±20% tolerance. It is a polarized, radial can design with screw terminals intended for general-purpose applications that require large bulk capacitance and high ripple handling.

Key value propositions include very high capacitance for bulk energy storage, high allowable ripple currents at both low and high frequency, a 5,000-hour endurance rating at 85°C, and a robust screw-terminal package in a φ90 × 220 mm form factor. The part is RoHS compliant and is in mass production.

Key Features

• Capacitance & Voltage — 680,000 µF (680 mF) rated at 25 V with ±20% tolerance (measured at 120 Hz, 20°C).
• High Ripple Current Handling — Low-frequency ripple current: 33.3 A at 120 Hz; high-frequency ripple current: 38.3 A at 100 kHz, supporting demanding ripple environments.
• Endurance & Temperature Range — Rated for 5,000 hours at 85°C; operating temperature range −40°C to +85°C.
• Tangent of Loss Angle (tan δ) — Specified tan δ (DF) of 1.00 measured at 120 Hz, 20°C.
• Leakage Current — Specified leakage current of 5,000 µA.
• Mounting & Package — Screw terminal radial can construction, φ90×220L (L: 22 cm × D: 9 cm) size, polarized; larger φ51+ diameters in the LNR series are furnished with 3-leg brackets as standard.
• Compliance & Availability — RoHS compliant and available in mass production from Nichicon’s LNR series.

Typical Applications

• Power-supply bulk smoothing — Large capacitance and high ripple current ratings make this part suitable for bulk energy storage and smoothing in general-purpose power supplies.
• Industrial and commercial power systems — Designed for equipment that requires sustained performance at elevated temperatures and significant ripple currents.
• DC bus and energy buffering — High capacitance and robust screw-terminal connections support DC bus stabilization and short-term energy buffering in general-purpose designs.

Unique Advantages

• Extremely high capacitance: 680,000 µF reduces the number of parallel components required for large bulk storage.
• High ripple-current capability: 33.3 A (120 Hz) and 38.3 A (100 kHz) ratings help manage thermal and electrical stress under ripple conditions.
• Long elevated-temperature life: 5,000 hours at 85°C provides predictable endurance for sustained operation.
• Robust screw-terminal package: Screw terminals and a large radial can support secure, high-current connections and mechanical stability.
• Standard bracket mounting for larger diameters: LNR series units φ51 and larger are furnished with 3-leg brackets as standard for reliable chassis attachment.
• RoHS compliant and mass-produced: Ensures environmental compliance and consistent supply for production programs.
