LNT1H474MSEN

The LNT1H474MSEN is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNT series designed for general-purpose applications that require high bulk capacitance and robust high-temperature performance. This polarized, radial can-style capacitor provides 470 mF at a 50 V rating and is built for applications that demand secure screw-terminal connections and high ripple handling.

Key Features

• High Capacitance — 470 mF nominal capacitance suitable for bulk energy storage and smoothing in general-purpose designs.
• Rated Voltage — 50 V rated voltage; the LNT series spans an extended range from 10 V up to 500 V.
• Wide Temperature Range — Operates from –40 °C to +105 °C (for 10 to 100 V range), matching the 50 V rating of this part.
• Load Life / Endurance — Load life of 2,000 hours at +105 °C under rated ripple current (for 10 to 250 V range); after endurance testing, capacitance change remains within ±20% and leakage current stays within initial specified limits.
• High Ripple Current Capability — 26.1 A at 120 Hz and 30.02 A at 100 kHz, supporting demanding AC ripple conditions.
• Screw-Terminal Mounting — Radial can with screw terminals for secure, low-impedance connections and reliable mechanical fastening.
• Polarized Device — Designed as a polarized electrolytic capacitor; observe polarity in application.
• Capacitance Tolerance — ±20% at 120 Hz, 20 °C.
• Leakage Current Specification — After 5 minutes’ application of rated voltage, leakage current is not more than 3√(C·V) μA or 5 mA, whichever is smaller (C: μF, V: V).
• RoHS Compliant — Complies with RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Package — Radial can with screw terminals; provided size dimension L: 25 × D: 10 cm and marking printed in white on a black sleeve. Height (seated) maximum: 9.843 inch.

Typical Applications

• General-purpose power supplies — Bulk smoothing and energy reservoir where high capacitance and screw-terminal connections are required.
• Industrial equipment — Filtering and ripple handling in general-purpose industrial electronics operating up to +105 °C.
• Power conversion and distribution — Bulk decoupling and ripple absorption in systems requiring high ripple current capability.

Unique Advantages

• High bulk energy storage: 470 mF nominal capacitance provides substantial charge reservoir for smoothing and hold-up functions.
• Thermal endurance at elevated temperature: Rated for operation to +105 °C with a specified load life of 2,000 hours at that temperature for the 10–250 V range.
• Screw-terminal robustness: Screw-terminal radial can package enables secure electrical and mechanical connections for higher-current applications.
• Strong ripple-handling capability: Specified ripple currents of 26.1 A (120 Hz) and 30.02 A (100 kHz) reduce heating and extend service life under AC stress.
• Measurable, controlled reliability: Endurance and shelf-life limits are defined (capacitance within ±20%, tan δ within 300% of initial spec, leakage current within initial limits), allowing predictable long-term behavior.
• Regulatory compliance: RoHS compliance ensures suitability for designs requiring restricted-substance adherence.
