LNR1J683MSEB

The LNR1J683MSEB from Nichicon is a screw‑terminal, radial can aluminum electrolytic capacitor in the LNR series, rated 68 mF (68,000 µF) at 63 V. Designed for general‑purpose electronic and power systems, it delivers high bulk capacitance with serviceable screw‑terminal connections and packaging suited for mass production.

Key electrical and mechanical attributes include an operating temperature range of −40 °C to +85 °C, a rated lifetime of 5,000 hours at 85 °C, and RoHS compliance, making it appropriate for applications that require high capacitance, substantial ripple handling and robust end‑of‑life performance.

Key Features

• High Capacitance: 68 mF (68,000 µF) nominal capacitance provides significant bulk energy storage for power smoothing and decoupling in systems requiring large capacitance at 63 V.
• Rated Voltage & Tolerance: Rated at 63 V with ±20% capacitance tolerance (measured at 120 Hz, 20 °C).
• Screw Terminal, Radial Can Package: Screw‑terminal mounting (radial can with screw terminals) enables secure, serviceable electrical connections; body diameter φ63.5 mm with standard 3‑leg bracket mounting for its size class and M5 nominal bolt diameter for terminals.
• Thermal and Endurance Specified: Operating from −40 °C to +85 °C; endurance specified as 5,000 hours at 85 °C with defined limits (capacitance change within ±15%, tan δ ≤175% of initial specified value, leakage current ≤ initial specified value after test).
• Leakage and Dissipation: Specified leakage current of 5,000 µA and tangent of loss angle (tan δ) of 0.3 (measurement conditions per product data).
• Ripple Current Capability: Rated ripple current of 15 A at 120 Hz and 17.25 A at 100 kHz for handling AC ripple in power applications.
• Environmental & Production: RoHS compliant and supplied in cardboard packing for mass production handling.
• Low‑Temperature Impedance Stability: For the 10–100 V rated range (applicable to this part), the impedance ratio Z(−40 °C)/Z(+20 °C) is specified with a maximum value of 12.

Typical Applications

• General‑purpose power systems — Suitable where high bulk capacitance (68,000 µF) at 63 V is required for energy storage, smoothing and decoupling in power rails.
• Industrial electronics — Screw‑terminal mounting and robust ripple current ratings provide practical installation and performance in industrial control and power assemblies.
• High‑capacity energy buffers — Specified lifetime (5,000 h at 85 °C) and leakage/tan δ characteristics make it appropriate for systems requiring predictable end‑of‑life behavior under elevated temperature service.

Unique Advantages

• Large bulk capacitance at mid‑voltage: 68 mF at 63 V supplies substantial stored charge for applications that need high capacitance without series stacking.
• Serviceable screw‑terminal connections: Screw terminals with M5 nominal bolts simplify assembly and maintenance compared with solder‑only devices.
• Defined ripple handling: 15 A (120 Hz) and 17.25 A (100 kHz) ripple ratings provide clear design parameters for thermal and ripple management in power systems.
• Specified endurance and stability: Endurance test criteria (5,000 h at 85 °C) with quantified limits for capacitance change, tan δ and leakage give predictable long‑term performance data for design validation.
• Low‑temperature behavior characterized: Impedance ratio specification at −40 °C (Z(−40 °C)/Z(+20 °C) ≤ 12 for this voltage range) helps predict performance in cold environments.
• Manufacturing and environmental readiness: RoHS compliance and cardboard packing support production workflows and environmental requirements.

Why Choose LNR1J683MSEB?

The LNR1J683MSEB positions itself as a high‑capacitance, screw‑terminal aluminum electrolytic solution for general‑purpose power and industrial designs that need substantial energy storage and clearly specified endurance and ripple performance. Its combination of 68 mF capacitance at 63 V, screw‑terminal convenience, quantified low‑temperature and endurance characteristics, and RoHS compliance make it well suited for designs requiring predictable electrical behavior and serviceable hardware.

This part is ideal for engineers and procurement teams specifying capacitors for mass production runs where cardboard packing and standardized mounting options (φ63.5 mm body with 3‑leg bracket) are preferred, and where clear, test‑based specifications for lifetime, leakage and dissipation angle are required for validation and reliability assessments.
