LNT2H103MSEJ

The LNT2H103MSEJ is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series, supplied as a radial can with screw terminals for secure power connections. It delivers 10 mF capacitance at a 500 V rated voltage, designed for general-purpose power applications that demand high ripple-current capability and elevated temperature endurance.

Key value propositions include high-voltage support up to 500 V, robust ripple-current performance, and a proven load life at elevated temperature: 2,000 hours at 105°C for this voltage range. The part is RoHS compliant and intended for installations that require durable, screw-terminal mounting and long-term reliability.

Key Features

• Package & Mounting — Radial can with screw terminals for secure, high-current connections and straightforward mechanical mounting.
• Capacitance & Voltage — 10 mF capacitance with a 500 V rated voltage and capacitance tolerance of ±20% (at 120 Hz, 20°C).
• High Ripple-Current Capability — Rated ripple current of 29.9 A at 120 Hz and 41.86 A at 100 kHz, supporting demanding AC ripple and switching loads.
• Temperature & Endurance — Operating temperature range of -25°C to +105°C for the 160–500 V range and a specified load life of 2,000 hours at 105°C when subjected to rated ripple current and DC bias.
• Reliability Parameters — Endurance and shelf-life characteristics per series datasheet: capacitance change within ±20%, tan δ within specified limits, and leakage current maintained at or below initial specified values after endurance tests.
• Extended Size & Voltage Range — Part of an extended series covering 10 V to 500 V and available in larger dimensions up to φ100 × 250L where required.
• Environmental Compliance — Compliant to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-voltage power supplies — For general-purpose designs requiring capacitor support up to 500 V and strong ripple-current handling to stabilize DC rails.
• Industrial power control — Screw-terminal mounting and 2,000-hour load life at 105°C fit power modules and control equipment operating at elevated temperatures.
• Energy conversion and inverters — High ripple-current ratings make the device suitable for smoothing and buffering in AC–DC and DC–DC conversion stages.
• Backup power and UPS systems — Provides bulk energy storage and filtering at high voltage levels in general-purpose backup and power-conditioning assemblies.

Unique Advantages

• High-voltage capability: Rated to 500 V, enabling use in higher-voltage rails without series stacking.
• Strong ripple performance: Significant ripple-current ratings at both low and high frequencies (29.9 A at 120 Hz; 41.86 A at 100 kHz) reduce heating and improve lifetime under AC stress.
• Robust elevated-temperature endurance: Load life specified at 2,000 hours at +105°C for this voltage range supports long-term operation in hot environments.
• Screw-terminal reliability: Secure electrical and mechanical connections suitable for high-current paths and repeated maintenance cycles.
• Wide series coverage: Part of an LNT series covering 10 V–500 V and extended physical sizes, simplifying selection across related design variants.
• Regulatory compliance: RoHS conformity supports deployment in regions requiring restricted-substance compliance.
