LNT1H103MSE

The LNT1H103MSE is a screw-terminal aluminum electrolytic capacitor from Nichicon’s LNT series designed for general-purpose power applications. It is a polarized, radial can style capacitor rated at 10 mF and 50 V, built for elevated ambient operation up to +105°C.

As a member of the LNT family, this part benefits from the series’ extended voltage coverage (10 V to 500 V) and long-life design options; for the 10–250 V range, the LNT series specifies a rated ripple-current life of 2,000 hours at +105°C when operated at rated ripple current.

Key Features

• Capacitance & Tolerance — 10 mF capacitance with ±20% tolerance at 120 Hz, 20°C.
• Rated Voltage — 50 V DC rated voltage for medium-voltage power applications.
• High Temperature Operation — Rated for operation up to +105°C (category range for 10–100 V: –40°C to +105°C).
• Load Life / Endurance — Series endurance specified as 2,000 hours at +105°C for the 10–250 V range when subjected to DC bias plus rated ripple current; after endurance, capacitance remains within ±20%, tan δ ≤ 300% of initial value, and leakage current remains at or below the initial specified level.
• Ripple Current Capability — 4.9 A at 120 Hz (low frequency) and 5.635 A at 100 kHz (high frequency) rated ripple-current figures.
• Mounting & Package — Screw-terminal radial can package for secure electrical and mechanical connection in panel- or chassis-mounted power assemblies.
• Polarization — Polarized (electrolytic) design; observe correct polarity during installation.
• Physical Size — Body dimensions approximately L: 8 cm × D: 3.5 cm for layout and enclosure planning.
• RoHS Compliance — Compliant with RoHS directives (2011/65/EU and (EU)2015/863).

Typical Applications

• General-purpose power supplies — Bulk smoothing and ripple reduction where a 50 V, high-capacitance screw-terminal capacitor is required and elevated operating temperatures are present.
• Industrial equipment — Energy buffering and decoupling in control cabinets and power modules that use screw-terminal mounting for robust connections.
• Power conversion modules — Filtering and ripple handling in medium-voltage DC link or auxiliary circuits that benefit from high ripple-current ratings and a 105°C temperature capability.

Unique Advantages

• Designed for elevated ambient temperatures — Rated to +105°C, enabling reliable performance in thermally demanding enclosures and equipment.
• High ripple-current handling — Explicit ripple-current specifications at both 120 Hz and 100 kHz provide clear parameters for thermal and lifetime planning in power designs.
• Screw-terminal mounting — Provides a durable electrical and mechanical connection for panel- or chassis-mounted power assemblies, simplifying installation and serviceability.
• Measured endurance characteristics — Endurance data (capacitance change, tan δ and leakage) tied to 2,000-hour life at 105°C gives predictable long-term behavior when operated at rated ripple and voltage.
• Series flexibility — Part of the LNT family, which spans 10 V to 500 V and extended size options, allowing designers to select consistent components across voltage and capacitance needs.
• Regulatory compliance — RoHS-compliant construction supports use in regulated markets and products.
