LNT2G682MSEJBB

The LNT2G682MSEJBB is an aluminum electrolytic capacitor in a screw-terminal radial can package. It is a polarized, general-purpose power capacitor rated at 6.8 mF (6800 µF) and 400 V, designed for applications that require high ripple current handling and extended operation up to 105°C.

Key value propositions include a high voltage rating, significant ripple current capability at both low and high frequencies, and a long rated lifetime at elevated temperature, making it suitable for demanding power electronics applications where bulk energy storage and DC-link smoothing are required.

Key Features

• Capacitance and Voltage — 6.8 mF (6800 µF) capacitance at a 400 V rated voltage for bulk energy storage and DC-link applications.
• High Ripple Current — Rated ripple current of 26.9 A at 120 Hz and 37.66 A at 100 kHz to support heavy AC ripple and fast switching environments.
• Temperature and Lifetime — Operating range of −25°C to +105°C with a rated life of 5000 hours at 105°C, supporting sustained high-temperature operation.
• Mounting and Package — Screw terminal mounting in a radial can package for secure electrical and mechanical connections in power assemblies.
• Polarized Design — Polar capacitor suitable for DC applications that require a defined polarity.
• Tolerance — Capacitance tolerance of −20% to +20% (±20%) at 120 Hz, 20°C for predictable design margins.
• RoHS Compliant — Manufactured to meet RoHS requirements for environmental compliance.
• Physical Size — Size dimensions L: 15 × D: 9 cm with a maximum seated height of 5.906 inch for mechanical planning.

Typical Applications

• Power supply bulk filtering — Use as bulk capacitance and smoothing in AC–DC and DC–DC power supplies where high ripple current capacity is needed.
• DC-link and energy storage — Suitable for DC-link and intermediate energy storage in inverters and converters that operate at elevated temperatures.
• Industrial power electronics — Integration into motor drives, UPS systems, and industrial power modules requiring robust screw-terminal connections and long life at 105°C.
