LNR1A334MSE

The LNR1A334MSE from Nichicon is a screw-terminal aluminum electrolytic capacitor in the LNR series, offering 330000 µF (330 mF) nominal capacitance at a 10 V rating. It is designed for general-purpose power applications that require large bulk capacitance, sustained ripple handling and long endurance in a radial can with screw terminals.

Engineered for operation from –40°C to 85°C with a rated endurance of 5000 hours at 85°C, this part pairs high capacitance with robust ripple-current capability to support demanding power-storage and smoothing roles.

Key Features

• Capacitance & Voltage — 330000 µF (330 mF) nominal capacitance with a rated voltage of 10 V and tolerance of –20% to +20%.
• Screw-Terminal Package — Radial can with screw terminals for secure mechanical mounting and direct electrical connections.
• High Ripple Current Capability — Rated ripple current of 15.9 A at 120 Hz (low frequency) and 18.29 A at 100 kHz (high frequency), enabling significant AC current handling during filtering and smoothing.
• Endurance & Temperature Range — Rated life of 5000 hours at 85°C and an operating temperature range of –40°C to 85°C.
• Leakage & Dissipation — Specified leakage current of 5000 µA and a tan δ (DF) of 0.9 measured at 20°C, 120 Hz.
• Form Factor — Body diameter φ63.5 mm and length 100 mm (φ63.5×100L), supplied in cardboard packing and available in mass production.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supply bulk filtering — Provides large-energy storage for smoothing and bulk decoupling in general-purpose power supplies.
• DC link and bus stabilization — Used where high capacitance and sustained ripple current are required to stabilize DC rails.
• Energy buffering — Suitable for applications that need short-term energy delivery or buffering in industrial and electronic systems.

Unique Advantages

• Large capacitance in a compact can: 330000 µF at 10 V delivers substantial energy storage while using a φ63.5×100 mm package.
• High ripple current support: Rated for 15.9 A (120 Hz) and 18.29 A (100 kHz), enabling reliable handling of AC ripple loads common in power electronics.
• Long rated life at elevated temperature: 5000 hours at 85°C provides predictable endurance for longer service intervals in sustained thermal environments.
• Robust screw-terminal connections: Screw terminals simplify mounting and enable secure electrical connections suitable for high-current paths.
• Wide operating temperature window: –40°C to 85°C supports deployment across many industrial and general-purpose environments.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements.
