LNR1K103MSE

The LNR1K103MSE is an aluminum electrolytic capacitor in a screw-terminal radial can package, rated 80 V with 10,000 µF nominal capacitance and ±20% tolerance. It is designed for general-purpose applications that require high capacitance, robust screw-terminal connections and long-term endurance.

Key performance attributes include a 5000-hour life at 85°C, low-frequency ripple current handling and low leakage current, making this part suitable for power-focused designs where durability and reliable electrical performance are required.

Key Features

• Capacitance & Voltage — 10,000 µF nominal capacitance at a rated voltage of 80 V with ±20% tolerance for bulk energy storage and filtering.
• Screw-Terminal Package — Radial can with screw terminals (φ35 × 80 mm body) for secure, low-resistance connections in rugged assemblies.
• High Ripple Current Capability — Supports 4.2 A ripple current at 120 Hz and 4.83 A at 100 kHz to accommodate demanding AC ripple conditions.
• Low Leakage & Loss — Specified leakage current of 2680 µA and a maximum tan δ of 0.2, providing predictable DC characteristics and dissipation behavior.
• Extended Endurance — Rated for 5000 hours of operation at 85°C under rated DC bias plus ripple current with defined limits on capacitance change and tan δ.
• Wide Operating Temperature Range — Specified for −40°C to +85°C to support deployments across varied thermal environments.
• Regulatory Compliance — RoHS-compliant construction.

Typical Applications

• General-Purpose Power Systems — Designed for general-purpose designs that require high-capacitance, high-voltage bulk storage with secure screw-terminal mounting.
• Industrial Equipment — Suitable for equipment requiring long endurance at elevated temperature (5000 h at 85°C) and an operating range down to −40°C.
• High-Ripple Power Circuits — Supports both low-frequency (120 Hz) and high-frequency (100 kHz) ripple currents for power filtering and smoothing tasks.

Unique Advantages

• High Capacitance per Volume — 10,000 µF at 80 V provides substantial bulk capacitance for energy storage and smoothing in a φ35 × 80 mm package.
• Screw-Terminal Reliability — Screw terminals deliver robust, low-resistance connections suitable for repeated installation and secure mounting in demanding environments.
• Designed for Ripple Duty — Specified ripple currents of 4.2 A (120 Hz) and 4.83 A (100 kHz) give clear electrical margins for designs with significant AC ripple content.
• Predictable Electrical Behavior — Low leakage current (2680 µA) and defined tan δ (0.2) enable accurate system-level power and thermal planning.
• Long-Term Endurance — 5000-hour rated life at 85°C under rated conditions supports maintenance cycles and lifetime budgeting for deployed systems.
• RoHS Compliance — Meets RoHS requirements for material compliance.
