LNT1K154MSEN

The LNT1K154MSEN is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNT series, offering very high bulk capacitance (150,000 µF / 150 mF) at an 80 V rated voltage. Designed for applications that demand large energy storage and sustained ripple handling, it combines a 105°C operating rating with screw‑terminal mounting for secure, high‑current connections.

Its specification set—including high ripple current capability, a -40°C to +105°C operating range, and a 2,000‑hour endurance at 105°C—targets general‑purpose power electronics where reliable DC link filtering, bulk smoothing, or large‑value capacitance is required.

Key Features

• High Capacitance — 150,000 µF (150 mF) provides substantial bulk energy storage for smoothing and buffering in power systems.
• 80 V Rated Voltage — Suitable for higher‑voltage DC link or bus applications that require an 80 V working voltage.
• 105°C Temperature Rating — Continuous operation across a wide thermal range (–40°C to +105°C) with specified endurance of 2,000 hours at +105°C.
• High Ripple Current — Rated ripple current of 21.6 A at 120 Hz and 24.84 A at 100 kHz to support high AC stress and reduce heating in high‑power designs.
• Screw Terminal Mounting — Robust screw‑terminal, radial can package for secure mechanical and electrical connections in high‑current installations.
• Electrical Characteristics — Capacitance tolerance ±20%, tan δ = 0.4, and specified leakage current of 5,000 µA, enabling predictable behavior in system design.
• Physical Package — Large form factor: φ90 × 220 L (approximately 22 cm × 9 cm), supplied in cardboard packing for handling and storage.
• RoHS Compliant — Conforms to RoHS requirements for materials compliance.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling where 150,000 µF and an 80 V rating reduce ripple and stabilize DC bus voltages.
• DC Link / Inverter Systems — Energy buffering in power conversion stages that require high ripple current handling and elevated temperature capability.
• Uninterruptible Power Supplies (UPS) — Energy reserve and smoothing in systems that demand large capacitance and reliable performance at elevated temperatures.

Unique Advantages

• Large Energy Capacity: 150,000 µF provides significant bulk storage to reduce ripple and support transient loads without increasing component count.
• High Ripple Endurance: Rated ripple currents at both low and high frequencies allow designers to size capacitors for demanding AC stress conditions with confidence.
• Thermal Reliability: Specified operation to +105°C and a 2,000‑hour rated life at that temperature deliver known endurance under elevated thermal stress.
• Secure, Serviceable Connections: Screw‑terminal construction enables robust mechanical mounting and high‑current terminations suitable for heavy‑duty installations.
• Predictable Electrical Specs: Clear tolerance (±20%), tan δ, and leakage current values make it straightforward to model performance in system simulations.
• Compliance and Packaging: RoHS compliance and cardboard packing support environmentally compliant procurement and safe handling.
