LNT1H154MSE

The LNT1H154MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series, offering 150,000 µF capacitance at a 50 V rating. It is a polarized, radial can style capacitor designed for general-purpose applications that require large bulk capacitance, high ripple handling and operation across a wide temperature range.

Key value comes from its high ripple-current capability and 2000-hour endurance at 105°C, combined with a robust screw-terminal mounting that facilitates secure electrical and mechanical connection in larger power assemblies.

Key Features

• High Capacitance — 150,000 µF (150 mF) provides significant bulk energy storage for general-purpose power applications.
• Rated Voltage — 50 V DC rating suitable for mid-voltage power rails and energy-storage nodes.
• Screw Terminal Mounting — Radial can with screw terminals enables strong, reliable connections for high-current circuits.
• High Ripple Current — Low-frequency ripple current of 19.5 A (120 Hz) and high-frequency ripple current of 22.43 A (100 kHz) to support demanding ripple conditions.
• Endurance at Elevated Temperature — Rated life of 2000 hours at +105°C when subjected to rated ripple current, supporting sustained operation in hot environments.
• Wide Operating Temperature — −40°C to +105°C operating range for use across varied ambient conditions.
• Loss and Leakage Characteristics — Specified tan δ of 0.75 (measured at 20°C, 120 Hz) and leakage current up to 5000 µA as provided in the product data.
• Physical Size & Mounting — Large form factor φ90 × 140 L (L: 14 cm × D: 9 cm) suitable where high capacitance density is required; packaged in cardboard for shipment.
• RoHS Compliant — Conforms to RoHS requirements as indicated in the product data.
• Capacitance Tolerance — ±20% tolerance at 120 Hz, 20°C for predictable design margins.

Typical Applications

• General-purpose power systems — Intended for designs that require large bulk capacitance and substantial ripple-current capability in general-purpose equipment.
• High-current power assemblies — Screw-terminal mounting and high ripple-current ratings facilitate use in assemblies handling significant AC ripple or transient currents.
• Harsh-environment electronics — Operates across −40°C to +105°C with a 2000-hour endurance rating at 105°C for sustained high-temperature operation.

Unique Advantages

• Substantial energy storage: 150,000 µF capacitance provides a large reservoir for smoothing and bulk storage needs without parallel stacking of smaller parts.
• Robust current handling: High ripple-current specifications at both low and high frequencies reduce thermal stress under AC-loaded conditions.
• Secure mechanical and electrical connection: Screw terminal package simplifies high-current terminations and improves mechanical stability in larger assemblies.
• High-temperature endurance: 2000-hour life at 105°C supports longevity where elevated junction or ambient temperatures are expected.
• Design predictability: Specified tan δ, leakage current, and ±20% capacitance tolerance enable engineers to size margins and thermal management accurately.
• Compliance and handling: RoHS compliance and cardboard packing support regulatory needs and practical handling during assembly and shipping.
