LNR1H154MSE

The LNR1H154MSE is an aluminum electrolytic capacitor in a screw-terminal, radial-can package designed for general-purpose applications requiring very high capacitance at 50 V. It combines a 150,000 µF nominal capacitance with screw-terminal mounting and a compact cylindrical form (φ76.2 × 120 mm) to provide substantial energy storage in industrial and power-system assemblies.

Built to Nichicon's LNR series specifications, this part delivers defined ripple-handling capability, endurance at elevated temperature, and clear electrical characteristics for engineering and procurement evaluation.

Key Features

• High Capacitance: 150,000 µF (150 mF) nominal capacitance for applications needing large charge storage.
• Rated Voltage: 50 V DC rated voltage suitable for medium-voltage DC buses and power rails.
• Screw-terminal, radial-can package: Screw terminal mounting with radial can; for the φ76.2 body size the nominal terminal bolt size is M5 and units are furnished with a 3‑leg mounting bracket as standard.
• Ripple Current Capability: 18.6 A at 120 Hz (low frequency) and 21.39 A at 100 kHz (high frequency) to support sustained AC ripple on DC lines within rated conditions.
• Leakage Current: Specified leakage current of 5000 µA; series datasheet defines leakage limits as not more than 3√C·V (µA) or 5 mA after 5 minutes at 20°C, whichever is smaller.
• Endurance and Temperature Range: 5000 hours rated lifetime at 85°C; operating temperature range −40°C to +85°C.
• Dissipation Factor and Tolerance: tanδ 0.55 (DF) at 20°C, 120 Hz; capacitance tolerance ±20%.
• RoHS Compliant: Meets RoHS status noted in the product data.
• Clear Identification: Marking is printed in black on a light-blue sleeve per series marking conventions.

Typical Applications

• General-purpose power systems: Provides high-capacitance bulk storage for systems that require stable DC bus capacitance.
• Industrial electronics: Suited to industrial control and power conditioning assemblies that use screw-terminal mounting for robust electrical and mechanical connections.
• Energy storage and smoothing: Used where large capacitance and defined ripple handling are needed to support transient and steady-state loads.

Unique Advantages

• Substantial energy capacity: 150,000 µF nominal capacitance reduces the need for many smaller discrete capacitors when large bulk capacitance is required.
• High ripple handling: Specified ripple currents at both low and high frequencies provide clear design limits for power-filtering and rail-conditioning applications.
• Engineered endurance: 5000-hour life rating at 85°C allows designers to plan for long-term performance in elevated-temperature environments.
• Robust mechanical interface: Screw-terminal mounting with M5 nominal bolt size and standard 3‑leg bracket for φ76.2 bodies simplifies secure installation and serviceability.
• Transparent electrical specifications: Leakage, tanδ, tolerance, and temperature limits are provided for straightforward engineering validation and BOM decisions.
