LNR2A154MSE

The LNR2A154MSE is an aluminum electrolytic capacitor in a screw-terminal, radial can package designed for general-purpose power applications. It delivers very high bulk capacitance (150,000 µF) at a 100 V rated voltage, combined with robust ripple current capability and long endurance.

Built for systems that require large energy storage and reliable DC bias performance, this Nichicon LNR series part offers a wide operating temperature range of –40°C to 85°C and an endurance specification of 5000 hours at 85°C.

Key Features

• High Capacitance & Voltage — 150,000 µF nominal capacitance at a 100 V rated voltage for substantial bulk energy storage in compact screw-terminal format.
• Ripple Current Handling — Low-frequency ripple current of 27 A (120 Hz) and high-frequency ripple current of 31.05 A (100 kHz) to support demanding AC/SMPS ripple conditions.
• Endurance & Temperature — Rated for 5000 hours at 85°C and specified to operate from –40°C to +85°C, with endurance performance tested under D.C. bias plus rated ripple current.
• Loss and Leakage — Tangent of loss angle (tanδ) specified at 0.3 (measured at 20°C, 120 Hz) and a maximum leakage current of 5000 µA.
• Robust Mechanical Design — Screw terminal mounting in a radial can (φ90 × 220 mm) with nominal terminal bolt diameter M5 for secure power connections and bracket mounting options for φ51 and larger sizes.
• Compliance & Availability — RoHS compliant and in mass-production status for predictable supply and regulatory alignment.

Typical Applications

• General-purpose power systems — Bulk energy storage and smoothing where large capacitance and screw-terminal connections are required.
• Industrial power electronics — Systems that benefit from high ripple current capability and long-term endurance at elevated temperatures.
• High-capacity DC link or filter banks — Applications needing substantial DC storage with secure mechanical mounting and high current handling.

Unique Advantages

• Large energy storage in a single component: 150,000 µF at 100 V reduces the need for parallel capacitors and simplifies system-level capacitance requirements.
• High ripple tolerance: 27 A (120 Hz) and 31.05 A (100 kHz) ripple ratings help manage heat and extend system reliability under continuous ripple stress.
• Validated endurance: 5000 hours at 85°C under rated conditions provides a verifiable lifecycle metric for thermal and bias stress planning.
• Measurable loss characteristics: tanδ = 0.3 (20°C, 120 Hz) offers a clear indicator for dissipation planning in design reviews.
• Secure screw-terminal mounting: M5 nominal terminal bolt and radial can construction enable robust electrical and mechanical connections for high-current applications.
• Regulatory alignment: RoHS compliance supports use in environments with restricted substance requirements.
