LNR1C683MSEN

The LNR1C683MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNR series, offering a large capacitance cell in a radial can with screw terminals for secure, high-current connections. It is intended for general-purpose electronic systems that require bulk capacitance and robust ripple-current handling at a 16 V rating.

Key value comes from its high capacitance (68,000 μF), defined endurance of 5,000 hours at 85°C, and measured ripple-current capability across low and high frequency ranges—making it suitable where substantial smoothing, energy buffering, or decoupling is required in designs using screw-terminal mounting.

Key Features

• Capacitance & Tolerance — 68,000 μF nominal capacitance with tolerance of -20% to +20% (±20% at 120 Hz, 20°C).
• Rated Voltage — 16 V DC rating for medium-voltage DC bus and power-supply applications.
• Loss and Dissipation — Tangent of loss angle (tan δ) specified at 0.4 (measurement condition: 20°C, 120 Hz) for predictable ESR-related behavior.
• Ripple Current Performance — Low-frequency ripple current 7.9 A at 120 Hz and high-frequency ripple current 9.085 A at 100 kHz, enabling effective handling of AC components on DC rails.
• Leakage Current — Specified leakage current of 3,120 μA after voltage application.
• Reliability / Endurance — Rated endurance of 5,000 hours at 85°C under DC bias plus rated ripple current; capacitance change within ±15% and leakage current meeting initial specified limits after the endurance period.
• Operating Temperature — Wide operating range from −40°C to +85°C.
• Mechanical / Mounting — Radial can with screw terminals (φ35 mm × 100 mm length; package size L: 10 cm × D: 3.5 cm) for secure bolted connections and robust mechanical retention.
• Polarized — Polar electrolyte capacitor requiring correct polarity in circuit.
• Compliance & Packaging — RoHS-compliant and supplied in cardboard packing; product is in mass production.

Typical Applications

• General-purpose power filtering — For systems requiring large bulk capacitance (68,000 μF) and a 16 V rating to smooth DC rails and reduce voltage ripple.
• Bulk decoupling / energy buffering — Screw-terminal mounting and high ripple-current specs (7.9 A @120 Hz, 9.085 A @100 kHz) support high-current decoupling where secure connections are required.
• Power-supply smoothing — Endurance of 5,000 hours at 85°C provides predictable long-term performance for continuous-duty power supplies operating within −40°C to +85°C.

Unique Advantages

• High capacitance in a compact can — 68,000 μF in a φ35 × 100 mm package delivers substantial energy storage without extensive board area or multiple smaller parts.
• Screw-terminal electrical and mechanical reliability — Screw terminals enable low-impedance, bolted connections suitable for high ripple currents and mechanical robustness.
• Frequency-aware ripple rating — Specified ripple currents at both 120 Hz and 100 kHz clarify performance across common low- and high-frequency stress conditions.
• Durability under elevated temperature — 5,000-hour endurance at 85°C provides a defined lifetime for thermal and electrical stress planning.
• Measured dissipation characteristics — A defined tan δ (0.4 at 20°C, 120 Hz) helps predict loss-related heating and select appropriate cooling or derating strategies.
• RoHS compliance and production-ready status — Environmentally compliant and in mass production for supply continuity.
