LNR1V683MSEB

The LNR1V683MSEB is an aluminum electrolytic capacitor in Nichicon’s LNR series, offering 68,000 µF capacitance at a 35 V rating with a screw-terminal radial can package. It is specified for general-purpose applications where large bulk capacitance and robust screw-terminal connections are required.

Designed for −40 °C to 85 °C operation with a 5,000‑hour endurance at 85 °C, this capacitor provides high-capacitance energy storage with defined ripple-current capability for use in systems requiring sustained performance under rated conditions.

Key Features

• Capacitance & Voltage — 68,000 µF (68 mF) rated at 35 V, offering substantial bulk energy storage for power systems.
• Package & Mounting — Screw terminal radial can construction (φ51 × 80 mm) for secure, low-resistance connections and mechanical stability.
• Operating Temperature — Specified for −40 °C to 85 °C operation, suitable for a wide ambient range.
• Endurance — 5,000 hours at 85 °C under DC bias plus rated ripple current, with capacitance change within ±15% after test.
• Ripple Current Performance — Rated ripple current of 9.3 A at 120 Hz and 10.7 A at 100 kHz to support AC superposition and switching environments.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA (whichever is smaller) at 20 °C.
• Tolerance & Polarization — ±20% capacitance tolerance and polarized design; intended for polarity-conscious circuits.
• RoHS Compliant — Conforms to RoHS requirements for environmental compliance.

Typical Applications

• General Purpose — Intended for general-purpose use where large bulk capacitance is needed and screw-terminal mounting provides secure electrical and mechanical connections.
• General Purpose — Suitable for systems requiring defined ripple-current handling at both low and high frequencies, per the specified 120 Hz and 100 kHz ratings.
• General Purpose — Deployed in designs that benefit from long-term endurance at elevated temperature, backed by the 5,000‑hour specification at 85 °C.

Unique Advantages

• High Bulk Capacitance: 68,000 µF provides substantial energy storage for smoothing and hold-up duty without multiple smaller capacitors in parallel.
• Screw-Terminal Robustness: Radial can with screw terminals enables tight, low-impedance connections and straightforward installation for power assemblies.
• Defined Ripple Capability: Explicit ripple-current ratings at 120 Hz and 100 kHz allow designers to size capacitors against measured AC stress in their systems.
• Endurance at Elevated Temperature: 5,000 hours at 85 °C under rated conditions provides a measurable reliability baseline for thermal-stressed applications.
• Clear Leakage Specification: Leakage current limit expressed as 3√CV (µA) or 5 mA after five minutes at 20 °C gives predictable leakage behavior for bias designs.
• Wide Operating Range: −40 °C to 85 °C rating supports a broad set of ambient conditions within the capacitor’s endurance envelope.
