LNR2E103MSE

The LNR2E103MSE is a screw-terminal aluminum electrolytic capacitor rated at 10,000 µF and 250 V, designed for general-purpose power applications that require high bulk capacitance and high-voltage handling. It is a polarized radial can with screw terminals and is offered in mass production packaging.

Built to an 85°C standard, this capacitor provides a specified endurance of 5,000 hours at 85°C under rated DC bias plus rated ripple current, making it suitable for designs that require sustained performance at elevated operating temperatures.

Key Features

• High Capacitance: 10,000 µF (10 mF) nominal capacitance for substantial bulk energy storage and smoothing.
• 250 V Rated Voltage: Rated voltage of 250 V for applications requiring higher DC voltage capability.
• Polarized Screw-Terminal Package: Radial can with screw terminals (suitable for M5 bolts on φ76.2 mm bodies) for secure, low-impedance connections and robust mounting; standard 3-leg bracket furnished for φ51 mm and larger sizes.
• Ripple Current Capability: Low-frequency ripple current 11.8 A at 120 Hz and high-frequency ripple current 14.16 A at 100 kHz, supporting substantial AC ripple handling in power circuits.
• Leakage Current: Specified leakage current 4,740 µA after rated voltage application (measurement conditions per product data).
• Endurance and Stability: 5,000 hours at 85°C endurance; after endurance test the capacitance change is within ±15%, tan δ ≤ 175% of initial specified value, and leakage current remains within initial specification (per series endurance criteria).
• Operating Temperature: Rated for operation from −25°C to +85°C for the 160–250 V range.
• Physical Size and Packaging: Body diameter φ76.2 mm × length 120 mm (L: 12 cm × D: 7.62 cm); supplied in cardboard packing and available in mass production.
• RoHS Compliant: Meets RoHS requirements as stated in the product data.

Typical Applications

• General-purpose power systems: Bulk energy storage and DC bus smoothing where high capacitance and a 250 V rating are required.
• Industrial power electronics: Use in systems that demand sustained ripple current capability and stable performance at elevated temperatures.
• High-voltage DC filter stages: Filtering and decoupling in high-voltage power supplies and converters needing large capacitance values.

Unique Advantages

• Substantial bulk capacitance: 10,000 µF provides high energy storage in a single component, reducing the number of parallel capacitors needed on the DC bus.
• High-voltage capability: 250 V rating allows use in higher-voltage supply rails without additional stacking or complexity.
• Robust mounting and connection: Screw-terminal construction with M5-compatible bolts and standard 3-leg bracket for secure, low-resistance electrical and mechanical connections.
• Designed for continuous operation at elevated temperature: 5,000-hour endurance at 85°C and specified post-endurance performance limits support reliability in demanding thermal environments.
• Strong ripple handling: High ripple current ratings at both 120 Hz and 100 kHz help manage AC stress in power conversion and filtering circuits.
• Regulatory readiness: RoHS compliance simplifies use in designs targeting restricted-substance requirements.
