LNR1C334MSEN

The LNR1C334MSEN is a screw-terminal, large-can aluminum electrolytic capacitor from Nichicon's LNR series. It provides 330 mF capacitance at a rated voltage of 16 V in a radial can with screw terminals for secure, high-current connections.

Engineered for general-purpose power applications, this capacitor delivers bulk energy storage and high ripple current capability with an operating temperature range of –40°C to +85°C and a rated endurance of 5000 hours at 85°C.

Key Features

• Capacitance: 330 mF nominal capacitance for bulk energy storage and smoothing.
• Rated Voltage: 16 V DC rated voltage suitable for low-voltage power rails.
• Package & Mounting: Radial can with screw terminals—designed for secure bolted connections in rack or chassis-mounted power assemblies.
• Temperature Range: –40°C to +85°C operating range (applies to 10 to 100 V rated products in the LNR series).
• Endurance: 5000 hours at 85°C under DC bias plus rated ripple current; capacitance change within ±15% after endurance test.
• High Ripple Current Handling: 25.1 A at 120 Hz and 28.86 A at 100 kHz, enabling effective smoothing of high-current ripple.
• Leakage Current Specification: After 5 minutes at rated voltage and 20°C, leakage is limited to 3√(C·V) µA or 5 mA, whichever is smaller.
• Low-Temperature Stability: Impedance ratio Z(–40°C)/Z(+20°C) ≤ 12 for rated voltages in the 10–100 V range (applies to this part’s rated voltage).
• RoHS Compliant: Meets RoHS environmental requirements.
• Physical Size: Body dimensions L: 12 × D: 6.35 cm for planning mechanical integration.

Typical Applications

• General-purpose power filtering — Bulk smoothing and energy buffering in power supply rails and DC bus systems for general-purpose electronics.
• High-ripple power circuits — Local energy storage where elevated ripple currents (specified at 120 Hz and 100 kHz) are present.
• Industrial and equipment power assemblies — Screw-terminal mounting supports robust mechanical and electrical connections in rack or chassis installations.

Unique Advantages

• Substantial capacitance in a single component: 330 mF provides large energy reserve, reducing the need for parallel capacitor networks.
• High allowable ripple current: Rated ripple currents at both low and high frequencies support demanding smoothing duties and reduce thermal stress under ripple load.
• Screw-terminal design for secure connections: Facilitates low-resistance, mechanically robust attachment for high-current paths.
• Proven endurance at elevated temperature: 5000-hour rating at 85°C with defined limits for capacitance change, tan δ, and leakage current—useful for continuous-duty applications.
• Measurable leakage limit: Clear leakage-current specification (3√CV µA or 5 mA max) enables predictable start-up and bias behavior.
• RoHS compliance: Meets environmental requirements for systems that require restricted-substance conformity.
