LNR1K154MSEN

The LNR1K154MSEN is a screw-terminal aluminum electrolytic capacitor designed for general-purpose power applications that require very high capacitance and robust ripple handling. It delivers 150,000 µF at a rated voltage of 80 V in a radial, screw-terminal can package suitable for secure bolted connections.

Engineered for long endurance, the capacitor is specified for 5,000 hours at 85°C and offers measurable loss characteristics (tanδ) and defined leakage current for reliable performance in demanding power circuits.

Key Features

• High Capacitance — 150,000 µF (150 mF) nominal capacitance, ideal for bulk energy storage and smoothing in high-capacitance designs.
• Rated Voltage — 80 V DC rated voltage for mid-voltage power rails.
• Mounting and Package — Screw terminal mounting in a radial, can-style package with dimensions φ90 × 170 mm for secure mechanical and electrical connections.
• Ripple Current Capability — Low-frequency ripple current 26.5 A (120 Hz) and high-frequency ripple current 30.48 A (100 kHz), supporting significant AC stress on power stages.
• Endurance — Life rating of 5,000 hours at 85°C with specified limits for capacitance change, tanδ, and leakage current after endurance testing.
• Electrical Losses — tanδ (DF) specified as 0.4 (measured at 20°C, 120 Hz) for predictable dissipation characteristics.
• Leakage Current — Specified leakage current up to 5,000 µA after 5 minutes at rated voltage (measurement condition per datasheet guidance).
• Temperature Range — Operating range from −40°C to +85°C to cover broad environmental conditions.
• Tolerance — Capacitance tolerance ±20% (measured at 20°C, 120 Hz).
• Compliance — RoHS compliant.

Typical Applications

• Power Filtering and Bulk Energy Storage — Large capacitance and high ripple current ratings make this capacitor suitable for bulk smoothing on DC rails and energy buffering in power-supply architectures.
• Industrial Power Electronics — Screw-terminal construction and high endurance at 85°C support use in industrial power assemblies where secure electrical connections are required.
• High-Current DC Circuits — Specified low- and high-frequency ripple current capability enables handling of substantial AC components in high-current DC applications.

Unique Advantages

• Large Stored Energy Capacity: 150,000 µF nominal capacitance provides significant bulk charge reserve to stabilize voltage rails under load transients.
• Robust AC Handling: Dual ripple current specifications (26.5 A at 120 Hz and 30.48 A at 100 kHz) allow design confidence across both low- and high-frequency stress conditions.
• Durable Endurance: Rated for 5,000 hours at 85°C with defined limits on capacitance change, tanδ, and leakage current to ensure long-term performance in continuous-duty applications.
• Secure Screw-Terminal Interface: Radial can with screw terminals facilitates reliable, low-resistance connections and mechanical stability in assembled power systems.
• Clear Electrical Characterization: Specified tanδ (0.4 at 20°C, 120 Hz) and defined leakage current provide predictable dissipation and hold-up behavior for engineering validation.
• Regulatory Compliance: RoHS compliance supports use in designs requiring restricted-substance conformance.
