LNT1C474MSEB

The LNT1C474MSEB is a screw‑terminal aluminum electrolytic capacitor in Nichicon’s LNT series, offering a high‑capacitance, polarized solution for general‑purpose power applications. It combines 470 mF capacitance at a 16 V rating with a rugged screw‑terminal radial can package designed for secure electrical and mechanical connections.

Designed for elevated operating temperatures up to +105°C and engineered for high ripple current capability, this part targets power filtering, bulk energy buffering and other general‑purpose roles where long life and reliable ripple handling are required.

Key Features

• Capacitance & Tolerance — 470 mF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• Rated Voltage — 16 V DC rating suitable for low‑voltage power applications.
• Screw‑Terminal Mounting — Radial can with screw terminals for robust, low‑impedance connections and straightforward panel or bracket mounting.
• High Ripple Current — Rated ripple current: 22.1 A at 120 Hz and 25.41 A at 100 kHz, enabling effective AC ripple smoothing and dynamic load handling.
• Operating Temperature Range — −40°C to +105°C to support elevated ambient environments (sectioned ranges per series specifications).
• Endurance at Elevated Temperature — Rated for 2,000 hours at +105°C under DC bias plus rated ripple current (per part specification).
• Polarized Can Package — Standard polarized aluminum electrolytic construction for bulk storage and decoupling duties.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).
• Part of LNT Series — Belongs to the LNT family, which offers an extended voltage range across the series from 10 V to 500 V and a wide range of capacitances.
• Compact External Dimensions — Physical size: L: 14 cm × D: 9 cm, providing large capacitance in a screw‑terminal radial can form factor.

Typical Applications

• General Power Filtering — Bulk smoothing and ripple reduction in DC power supplies where 470 mF and high ripple current capability reduce voltage ripple under load.
• Energy Buffering — Short‑term energy storage for hold‑up or load‑transient support using the capacitor’s large capacitance and screw‑terminal connections.
• Industrial Power Modules — Local decoupling and smoothing in industrial power electronics where elevated operating temperature and secure terminals are required.

Unique Advantages

• High ripple handling — Rated ripple currents of 22.1 A (120 Hz) and 25.41 A (100 kHz) let designers manage significant AC stress without oversizing filtration networks.
• Long life at elevated temperature — Specified 2,000 hours at +105°C under rated conditions, supporting reliable operation in hot environments.
• Secure, low‑impedance terminations — Screw‑terminal construction provides robust mechanical fastening and reliable electrical contact for high‑current paths.
• Large capacitance in a compact can — 470 mF in a 14 cm × 9 cm package delivers substantial energy storage where PCB‑mounted axial solutions are impractical.
• Series flexibility — As part of the LNT series, it benefits from a family portfolio that spans broad voltage and capacitance options for design scalability.
• RoHS compliance — Meets current RoHS requirements for restricted substances, aiding regulatory conformity in assemblies.
