LNT1E154MSE

The LNT1E154MSE is a screw-terminal aluminum electrolytic capacitor delivering 150,000 µF of bulk capacitance at a 25 V rating. It is a radial can with screw terminals designed for general-purpose applications that require high capacitance and robust ripple-current handling.

Engineered for operation from −40°C to +105°C with a rated endurance of 2,000 hours at 105°C, this part provides high low- and high-frequency ripple current capability while maintaining a compact φ63.5 × 120L form factor and screw-terminal mounting for secure power connections.

Key Features

• Bulk Capacitance — 150,000 µF (150 mF) nominal capacitance with ±20% tolerance, providing substantial energy storage for bulk filtering and smoothing in power systems.
• Rated Voltage — 25 V DC rating for medium-voltage power rails and storage applications.
• High Ripple Current Capability — 13.8 A at 120 Hz (low frequency) and 15.87 A at 100 kHz (high frequency), supporting heavy ripple and transient loads.
• Loss Tangent — tan δ = 0.7 (DF) measured at 20°C and 120 Hz, specified for predictable dissipation characteristics.
• Reliability & Endurance — Rated for 2,000 hours life/endurance at +105°C under specified ripple conditions, with leakage current specified at 5,000 µA.
• Robust Mechanical & Mounting — Screw terminal, radial can package with size φ63.5 × 120L (L: 12 cm × D: 6.35 cm), designed for secure connections in power assemblies.
• Temperature Range & Compliance — Operating range −40°C to +105°C and RoHS-compliant; shipped in cardboard packing and available in mass production.

Typical Applications

• General-purpose power electronics — Bulk smoothing and energy storage on 25 V power rails where large capacitance and ripple handling are required.
• Industrial power supplies — DC link and bulk reservoir applications that demand sustained ripple current and high capacitance in a screw-terminal package.
• UPS and backup systems — Energy storage and filtering in systems needing high-capacity capacitors with proven 105°C endurance.

Unique Advantages
