LNR1J154MSE

The LNR1J154MSE is a screw‑terminal aluminum electrolytic capacitor designed for general‑purpose power applications that require large bulk capacitance. It features a 150,000 µF (150 mF) rated capacitance at 63 V with polarized screw terminals and a rugged radial can package.

Engineered for sustained operation, this part offers high ripple current capability, defined loss characteristics, and a 5,000‑hour endurance rating at 85°C, making it suitable for designs that need reliable bulk energy storage and DC‑rail smoothing within an operating range of −40°C to 85°C.

Key Features

• Capacitance & Voltage — 150,000 µF (150 mF) rated capacitance at 63 V with ±20% tolerance, providing substantial bulk storage for DC rails and power conditioning.
• High Ripple Current — Handles 26,000 mA at 120 Hz (low frequency) and 29,900 mA at 100 kHz (high frequency), supporting applications with significant AC ripple on the DC bus.
• Endurance & Reliability — 5,000 hours rated life at 85°C under rated DC bias plus ripple current; capacitance and leakage limits defined per endurance specification.
• Loss Characteristics — Specified tangent of loss angle (tan δ) of 0.5 at 20°C and 120 Hz for predictable dissipation and thermal behavior.
• Leakage Current — Specified leakage current of 5,000 µA (after rated voltage application conditions), useful for margining and system standby calculations.
• Mechanical & Mounting — Screw terminal radial can with body diameter φ76.2 mm and length 140 mm; terminal design accommodates M5 nominal bolt attachment for robust connections.
• RoHS Compliant & Production Ready — RoHS status compliant and listed as mass production, packaged in cardboard for handling and storage.

Typical Applications

• Power supply bulk smoothing — Use where 150,000 µF at up to 63 V is required to stabilize DC rails and reduce voltage ripple under high load currents.
• Energy storage for industrial power systems — Large capacitance and high ripple current ratings support short‑term energy buffering and ride‑through in industrial power electronics.
• Inverter and motor drive DC link — Screw‑terminal mounting and high ripple capability suit DC‑link bulk capacitance roles in motor drives and inverters operating within −40°C to 85°C.

Unique Advantages

• Substantial bulk capacitance: 150,000 µF provides significant charge reservoir for designs needing high energy density in a single component.
• High AC ripple handling: Rated ripple currents of 26 A (120 Hz) and 29.9 A (100 kHz) reduce the need for parallel capacitors in many high‑ripple environments.
• Defined thermal endurance: 5,000 hours at 85°C gives designers a clear reliability baseline for lifetime planning under elevated temperature stress.
• Screw terminal robustness: M5‑nominal screw terminals and a radial can package enable secure mechanical and electrical connections in high‑current assemblies.
• Predictable loss and leakage: Specified tan δ and leakage current values support thermal budgeting and standby current calculations.
• Production availability: Mass production status and cardboard packing simplify procurement and integration into production workflows.
