LNT1H154MSEN

The LNT1H154MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, offering very high bulk capacitance in a radial can with screw terminals for secure, low-impedance connections. Designed for general-purpose applications, it delivers high ripple-current capability and operation across a wide temperature range for demanding power systems.

With a rated capacitance of 150,000 µF at 50 V, operation to +105 °C, and RoHS compliance, this part is intended for designs that require large energy storage, effective smoothing, and reliable performance in elevated-temperature environments.

Key Features

• High Capacitance & Voltage: 150,000 µF nominal capacitance at 50 V provides substantial bulk energy storage for power rails and smoothing applications.
• High Ripple-Current Performance: Rated ripple current of 19.5 A at 120 Hz and 22.43 A at 100 kHz supports heavy AC stress and helps minimize temperature rise under load.
• Wide Operating Temperature: Specified for −40 °C to +105 °C to accommodate thermal environments where elevated operating temperatures are expected.
• Robust Endurance: Lifetime specified as 2000 hours at 105 °C, providing predictable long-term performance in high-temperature applications.
• Screw-Terminal Mounting: Radial can package with screw terminals simplifies panel or busbar connections and delivers secure mechanical and electrical contacts.
• Polarized Design & Tolerance: Polar capacitor with capacitance tolerance of −20% to +20% for straightforward specification in DC power systems.
• RoHS Compliant: Conforms to RoHS requirements for environmental compliance in global product designs.
• Compact Footprint for Capacity: Physical dimensions L: 14 × D: 9 cm (radial can) allow high capacitance density in a mountable package.

Typical Applications

• Power Supply Smoothing: Bulk energy storage and ripple suppression for DC power supplies and intermediate buses where high capacitance and ripple handling are required.
• Energy Storage in Power Electronics: Buffering and decoupling for converters and inverters that impose high AC ripple and demand stable bulk capacitance at elevated temperatures.
• Industrial Control Systems: General-purpose use in industrial equipment needing reliable bulk capacitance with screw-terminal mounting for secure field connections.

Unique Advantages

• Large Stored Energy: 150,000 µF at 50 V provides significant capacitance for smoothing and ride-through without multiple smaller capacitors.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz reduce overheating risk and extend service life under AC stress.
• High-Temperature Operation: Rated to +105 °C, enabling use in warm enclosures and near heat-generating power components.
• Secure Screw-Terminal Connections: Screw-terminal radial can package simplifies installation and provides a durable mechanical and electrical interface for heavy-current circuits.
• Predictable Lifespan: Specified lifetime at temperature gives clear guidance for maintenance intervals and lifetime planning in deployed systems.
• Standards-Conscious Design: RoHS compliance supports regulatory requirements for many commercial and industrial products.
