LNR1K104MSE

The LNR1K104MSE is an aluminum electrolytic capacitor in Nichicon’s LNR series, configured with screw-terminal connections for secure, high-current power connections. It provides 100000 µF capacitance at an 80 V rating and is designed for general-purpose power electronics requiring large bulk capacitance and sustained ripple handling.

Packaged in a radial can with screw terminals (φ76.2 × 140L), the part is RoHS compliant, produced for mass production, and supplied in cardboard packing.

Key Features

• Capacitance & Voltage — 100000 µF (100 mF) rated at 80 V provides substantial bulk energy storage for power circuits.
• Screw Terminal Mounting — Radial can with screw terminals and M5 nominal bolt interface for robust electrical and mechanical connection.
• High Ripple Current — Rated ripple current of 21.3 A at 120 Hz (low frequency) and 24.5 A at 100 kHz (high frequency) to support heavy AC ripple conditions.
• Endurance — 5000 hours at 85°C with D.C. bias plus rated ripple current; after endurance test, capacitance change is within ±15%, tan δ remains ≤175% of initial spec, and leakage current remains at or below initial specified value.
• Leakage & Loss — Specified leakage current of 5000 µA (5 mA). Tangent of loss angle (tan δ) specified for performance verification (datasheet measurement at 120 Hz, 20°C).
• Operating Temperature — Rated for operation from −40°C to +85°C, suitable for a wide range of ambient conditions defined by the product datasheet.
• Physical & Mounting Dimensions — Body diameter φ76.2 mm and length 140 mm; terminal pitch W = 31.8 mm and terminal length ℓ = 6 mm for φ76.2 size; standard supply includes 3-leg bracket mounting (dimensions per datasheet).

Typical Applications

• General-purpose power systems — Bulk capacitance and high ripple current capability make this capacitor suitable for smoothing and energy storage in general-purpose power electronics.
• High-current DC link and filtering — Large capacitance and robust screw-terminal connections support DC link filtering and high-ripple environments where sustained ripple handling is required.
• Industrial power modules — Durable endurance rating at 85°C and heavy-duty terminals suit long-run applications in industrial power assemblies.

Unique Advantages

• Large bulk capacitance: 100000 µF provides significant charge storage to stabilize DC rails and absorb transient energy.
• Designed for high ripple loads: Rated ripple currents of 21.3 A (120 Hz) and 24.5 A (100 kHz) reduce thermal stress in high-ripple applications.
• Robust electrical connections: Screw terminal and M5 bolt interface deliver low-resistance, mechanically secure terminations for heavy-current wiring.
• Long endurance under bias: 5000 hours at 85°C with defined post-test limits (±15% capacitance change, tan δ ≤175% of initial, leakage ≤ initial) supports predictable long-term performance.
• Wide operating temperature: −40°C to +85°C rating enables use across common industrial ambient ranges specified by the datasheet.
• RoHS compliant and production-ready: Conforms to RoHS and is supplied for mass production with cardboard packing for handling and logistics.
