LNR1E104MSEN

The LNR1E104MSEN is an aluminum electrolytic capacitor in Nichicon's LNR series, configured with screw terminals for secure, high-current connections. It delivers 100,000 µF (100 mF) nominal capacitance at a 25 V rated voltage and is intended for general‑purpose power applications that require large bulk capacitance and robust ripple handling.

Designed for applications operating between −40°C and 85°C, the LNR1E104MSEN combines high ripple current capability and long endurance (5,000 hours at 85°C) to support sustained DC bias and ripple workloads in systems requiring substantial energy storage.

Key Features

• High Capacitance — 100,000 µF (100 mF) nominal capacitance for bulk energy storage and smoothing in power systems.
• 25 V Rated Voltage — Suitable for low-voltage DC link and power supply applications requiring a 25 V working voltage.
• Screw Terminal Mounting — Radial can with screw terminals enables reliable, low‑resistance connections for high current paths; ideal for chassis or bracketed mounting.
• Elevated Ripple Current Capability — Low-frequency ripple current of 12 A (120 Hz) and high-frequency ripple current of 13.8 A (100 kHz) to handle substantial AC ripple without excessive heating.
• Endurance and Temperature Rating — Rated for 5,000 hours at 85°C with operating temperature range of −40°C to 85°C, meeting the LNR series endurance criteria after DC bias plus rated ripple current.
• Electrical Loss and Leakage — Specified tangent of loss angle (tan δ) of 0.45 (measured at 20°C, 120 Hz) and a measured leakage current of 4,740 µA for predictable electrical performance.
• Physical Size and Packaging — Large-format body (φ51 × 100 mm / D: 5.1 cm × L: 10 cm) supplied in cardboard packing; φ51 units are furnished with 3‑leg mounting brackets as standard.
• Compliance — RoHS‑compliant construction.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy storage where large capacitance at 25 V and high ripple current capacity reduce output ripple and stabilize DC rails.
• Power electronics and converters — DC link and intermediate bus filtering in systems that require sustained ripple handling and long endurance at elevated temperature.
• Industrial equipment — Chassis- or bracket-mounted power systems benefiting from screw-terminal connections and robust mounting provided with φ51 units.

Unique Advantages

• Very large bulk capacitance: 100,000 µF provides significant charge storage for smoothing and energy buffering in demanding power designs.
• High ripple current handling: 12 A (120 Hz) and 13.8 A (100 kHz) ratings reduce internal heating and support higher AC stress levels without premature degradation.
• Designed for continuous operation: 5,000-hour endurance at 85°C under DC bias plus rated ripple current supports longer service life in elevated-temperature environments.
• Screw-terminal convenience: Robust terminals and standard 3‑leg brackets (for φ51) simplify secure electrical and mechanical integration into assemblies.
• Measured electrical characteristics: Specified tan δ (0.45 at 20°C, 120 Hz) and leakage current (4,740 µA) enable predictable impedance and loss budgeting during design.
• Regulatory compliance: RoHS compliance supports use in regions requiring hazardous‑substance restrictions.
