LNT2G103MSEJ

The LNT2G103MSEJ from Nichicon is a large can aluminum electrolytic capacitor in the LNT series built with screw terminals for robust electrical and mechanical connections. It provides 10,000 µF capacitance at a 400 V rating and is designed for general-purpose power applications requiring high bulk capacitance and high ripple handling.

Key value for designers comes from its high ripple-current capability, long endurance at elevated temperature (5,000 hours at 105°C), and a wide operating temperature range of −25°C to +105°C—attributes that support sustained operation in demanding power systems.

Key Features

• Capacitance and tolerance — 10,000 µF nominal capacitance with ±20% tolerance (−20% to +20%) specified at 120 Hz, 20°C.
• Rated voltage — 400 V DC rating suitable for high-voltage power stages and bulk energy storage.
• Screw-terminal package — Radial can with screw terminals for secure, high-current connections and straightforward mechanical mounting.
• High ripple-current capability — Rated low-frequency ripple current of 32.9 A at 120 Hz and high-frequency ripple current of 46.06 A at 100 kHz, supporting demanding power-conversion loads.
• Endurance at elevated temperature — 5,000 hours rated life at 105°C with rated ripple current applied, enabling long-term operation in hot environments.
• Operating temperature range — −25°C to +105°C to cover a wide range of industrial ambient conditions.
• Loss characteristics and leakage — Tangent of loss angle (tan δ) specified at 0.2 (measured at 20°C, 120 Hz); leakage current specified at 5,000 µA (5 mA) after 5 minutes.
• Physical size and packaging — Large-can footprint (φ90 × 190 mm) with cardboard packing for bulk handling. Polarized device, radial can style.
• RoHS compliant — Meets RoHS directive requirements.

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing where high voltage and large capacitance are required.
• Power converters and inverters — Filtering and ripple absorption in high-current converter outputs, supported by the specified 120 Hz and 100 kHz ripple-current ratings.
• UPS and backup power systems — Energy reservoir for hold-up and transient support using the capacitor’s large capacitance and endurance at 105°C.
• General-purpose industrial equipment — High-capacitance, high-voltage requirements in machinery and electronic subsystems that require robust screw-terminal connections.

Unique Advantages

• High bulk capacitance at high voltage — 10,000 µF at 400 V provides substantial energy storage in a single component, reducing board population and simplifying design.
• Designed for sustained high-temperature operation — 5,000-hour endurance at 105°C helps maintain performance and reliability in demanding thermal environments.
• Strong ripple-current performance — Specified ripple-current ratings at both low and high frequencies allow confident use in high-current power stages and switching environments.
• Secure, serviceable connections — Screw terminals enable reliable high-current terminations and straightforward field wiring or replacement.
• Clear electrical loss and leakage specifications — Specified tan δ and leakage current values allow designers to model dissipation and standby performance accurately.
• RoHS compliance and mass-production availability — Suitable for volume deployment with environmental compliance and established manufacturing status.
