LNR2A154MSEN

The LNR2A154MSEN is a screw-terminal aluminum electrolytic capacitor offering 150,000 µF capacitance at a 100 V rating in a large can package. Designed for general-purpose use, it provides high capacitance and substantial ripple-current capability for demanding power applications.

Key electrical and mechanical attributes include a rated voltage of 100 V, low- and high-frequency ripple-current ratings, a wide operating temperature range of −40°C to +85°C, and a 5,000-hour endurance at 85°C. The part is RoHS compliant and available as a mass-production item with cardboard packing.

Key Features

• High Capacitance — 150,000 µF (150 mF) capacitance suitable for bulk energy storage and smoothing in power systems.
• Rated Voltage — 100 V rated voltage for high-voltage DC applications.
• 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 high-demand ripple environments.
• Endurance and Stability — Rated for 5,000 hours at 85°C; endurance spec requires capacitance change within ±15%, tan δ ≤ 175% of initial, and leakage current ≤ initial specified value after the test.
• Leakage and Loss — Specified leakage current up to 5,000 µA and a tangent of loss angle (tan δ) of 0.3 (measured at 20°C, 120 Hz).
• Temperature Range — Operating range from −40°C to +85°C to accommodate a broad set of environments.
• Screw Terminal Mounting — Robust screw terminal can-style package (radial can with screw terminals) for secure electrical and mechanical connections.
• Physical Size & Packaging — Large form factor φ90 × 220L (L: 22 × D: 9 cm) with cardboard packing; standard product in mass production.
• Regulatory — RoHS compliant.

Typical Applications

• General Purpose Power Systems — Bulk energy storage and smoothing where very high capacitance at 100 V is required.
• Power Conversion and Distribution — Applications that demand sustained ripple-current handling at both low and high frequencies.
• Industrial Equipment — Systems operating within −40°C to +85°C that require long-duration endurance (5,000 hours at 85°C).

Unique Advantages

• Large Capacitance Density — 150,000 µF provides substantial charge storage in a single component, reducing the need for parallel capacitors.
• High Ripple Capability — Specified 27 A (120 Hz) and 31.05 A (100 kHz) ripple ratings help manage thermal stress and filtering demands in high-current circuits.
• Long Endurance at Elevated Temperature — 5,000-hour rating at 85°C with defined post-test limits for capacitance, tan δ, and leakage ensures predictable performance over life.
• Secure Screw-Terminal Interface — Can-style screw terminals provide reliable, low-impedance connections for heavy-current paths.
• Clear Specification Limits — Defined leakage current, tan δ, and tolerance (±20%) at measurement conditions (20°C, 120 Hz) simplify selection and design validation.
• RoHS Compliance — Environmentally compliant for global product planning.
