LNR1H154MSEN

The LNR1H154MSEN is a screw‑terminal aluminum electrolytic capacitor engineered for general-purpose power applications that require very high bulk capacitance and robust ripple handling. It is a radial, can‑style screw terminal unit rated at 150000 µF (150 mF) and 50 V, optimized for systems operating between −40°C and 85°C.

Designed for installations where secure electrical connections and sustained performance at elevated temperatures are required, this capacitor delivers high stored energy, substantial low‑ and high‑frequency ripple capability, and long endurance for continuous service environments.

Key Features

• High Bulk Capacitance — 150000 µF (150 mF) nominal capacitance for energy storage, smoothing, and hold‑up applications.
• 50 V Rated Voltage — Rated for 50 V DC use as indicated by the part number.
• Screw Terminal Mounting — Rugged radial can with screw terminals (M5 for φ76.2 body), providing secure high‑current connections for power systems.
• Strong Ripple Performance — Rated ripple current of 18.6 A at 120 Hz (low frequency) and 21.39 A at 100 kHz (high frequency) to support heavy AC ripple and switching environments.
• Endurance at Elevated Temperature — 5000 hours life at 85°C with defined limits: capacitance change within ±15% and tanδ not exceeding 175% of initial specified value after endurance test.
• Leakage and Loss Characteristics — Specified leakage current of 5000 µA (after 5 minutes’ application of rated voltage per the series specification) and maximum tanδ of 0.55 for this part.
• Wide Operating Range — Rated for operation from −40°C to 85°C to accommodate a broad set of industrial and commercial environments.
• Form Factor — Body size φ76.2 × 120 mm length, radial can with standard mounting brackets for larger diameters.
• Regulatory Status — RoHS compliant.
• Tolerance — Capacitance tolerance of ±20% (120 Hz, 20°C).

Typical Applications

• Power supply smoothing — Bulk energy reservoir to reduce voltage ripple and stabilize DC rails in industrial and commercial power supplies.
• Power conversion and DC link — Energy storage and ripple handling for converters and inverters that require high capacitance and large ripple current capacity.
• Backup and hold‑up circuits — Provide stored energy for short‑term hold‑up during transient events or brief power interruptions.
• Industrial electronics — Heavy‑duty systems and control equipment that need durable capacitors with long endurance at elevated temperature.

Unique Advantages

• Substantial stored energy: 150000 µF provides significant bulk capacitance for smoothing, hold‑up, and energy buffering, reducing the need for parallel components.
• High ripple capability: Dual ripple ratings (18.6 A @ 120 Hz and 21.39 A @ 100 kHz) support both low‑frequency and high‑frequency ripple environments common in power electronics.
• Robust mounting and connection: Screw terminal radial can with mounting bracket options ensures reliable mechanical and electrical connection in demanding assemblies.
• Durability at temperature: 5000 h endurance at 85°C with defined post‑test limits for capacitance, tanδ, and leakage current supports long service life in elevated‑temperature installations.
• Wide ambient range: −40°C to 85°C operating range accommodates a variety of commercial and industrial deployment conditions.
• Standards‑driven leakage specification: Leakage current aligns with series criteria (measurement after 5 minutes’ application of rated voltage), enabling predictable design behavior.
