LNR1K154MSE

The LNR1K154MSE is a screw‑terminal aluminum electrolytic capacitor from Nichicon's LNR series, designed for general-purpose power applications requiring large bulk capacitance and robust ripple handling. It delivers 150,000 µF at a rated voltage of 80 V in a radial can with screw terminals and is offered in mass production with cardboard packing.

Engineered for continuous operation up to 85°C, the LNR1K154MSE targets power electronics and industrial systems that need high bulk energy storage, DC-link smoothing, and reliable long‑term endurance under rated ripple and DC bias conditions.

Key Features

• High Capacitance: 150,000 µF (150 mF) bulk capacitance for substantial energy storage and smoothing of DC rails.
• 80 V Rated Voltage: Suitable for medium‑voltage DC applications requiring a robust 80 V rating.
• Screw Terminal, Radial Can Package: Screw‑terminal mounting and radial can (can with screw terminals) simplify high‑current connections and mechanical integration; body size is φ90 × 170 mm (L: 17 × D: 9 cm).
• High Ripple Current Capability: 26.5 A at 120 Hz (low frequency) and 30.48 A at 100 kHz (high frequency) for demanding ripple conditions.
• Leakage Current Specified: Leakage current up to 5,000 µA (measured condition per datasheet), enabling predictable standby and idle behavior.
• Endurance and Temperature Range: Rated for 5,000 hours at 85°C with an operating temperature range of −40°C to +85°C.
• RoHS Compliant: Meets RoHS environmental requirements.
• Standard Mounting Bracket: Larger body types in the LNR series are furnished with a 3‑leg bracket as standard (φ51 and larger), supporting secure mechanical installation.

Typical Applications

• Industrial Power Supplies: Bulk energy storage and DC‑link smoothing where 150,000 µF and an 80 V rating reduce voltage ripple and assist voltage holding during load transients.
• Power Converters and Inverters: DC‑link capacitor for converters that require high ripple current handling at both 120 Hz and high switching frequencies (100 kHz).
• UPS and Energy Buffering: Energy buffering and ride‑through capability in backup systems leveraging long endurance at elevated temperature.
• Motor Drives and VFDs: Smoothing and bulk storage on DC buses for motor controllers and variable‑frequency drives that demand reliable ripple performance.

Unique Advantages

• Substantial Bulk Storage: 150,000 µF capacity minimizes required parallel capacitance to achieve large energy reservoirs, simplifying BOM for bulk storage needs.
• Robust Ripple Handling: Specified ripple currents of 26.5 A (120 Hz) and 30.48 A (100 kHz) enable operation with both low‑frequency and high‑frequency ripple sources.
• Designed for High‑Temperature Endurance: Rated 5,000 hours at 85°C for durability in sustained elevated‑temperature environments.
• Serviceable Mechanical Terminals: Screw terminals facilitate secure, low‑impedance current connections and straightforward field wiring or replacement.
• Predictable Leakage Behavior: Leakage current specified at 5,000 µA (maximum under datasheet conditions) provides a clear parameter for standby and charging design considerations.
• Environmentally Compliant: RoHS compliance supports designs targeting regulated markets and reduces material‑restriction risks.
