LNX2L822MSEK

The LNX2L822MSEK is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-voltage, high-ripple industrial power applications. Built for inverter circuitry and extra-high-voltage power supplies, it combines large capacitance with a screw-terminal package for robust electrical and mechanical connections.

Key value comes from its 8.2 mF capacitance at 550 V, high ripple-current capability, and engineered endurance at elevated temperature, making it suitable for demanding industrial power-conversion environments that require reliable bulk energy storage.

Key Features

• Capacitance & Tolerance — 8.2 mF (8200 µF) with ±20% tolerance at 120 Hz, 20°C, providing substantial bulk capacitance for energy storage and smoothing.
• Rated Voltage — 550 V DC rating for extra‑high‑voltage applications.
• High ripple current capability — Rated ripple currents of 21.6 A at 120 Hz and 30.24 A at 100 kHz to support heavy AC ripple loads common in power conversion.
• Endurance at elevated temperature — Designed to meet endurance specifications after 5,000 hours at +85°C when exposed to DC bias plus rated ripple current (specific to 500 V and 550 V parts).
• Operating temperature range — −25°C to +85°C to cover common industrial operating conditions.
• Screw-terminal radial can — Robust mounting and electrical connections suitable for high-current, high-reliability assemblies; package dimensions: L: 22 × D: 10 cm, mounting variants available per series guidelines.
• Leakage current specification — After 5 minutes at rated voltage, leakage is not more than 3√(C·V) µA or 5 mA, whichever is smaller (at 20°C), allowing predictable design of startup and standby conditions.
• Low-temperature impedance behavior — Impedance ratio Z(−25°C)/Z(+20°C) up to 8, supporting performance expectations across the specified temperature range.
• Flame-retardant electrolyte option — Flame-retardant electrolyte is available for types in this series to address safety considerations.
• RoHS compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies — Bulk energy storage and smoothing in high-voltage industrial supply rails where robust capacitance and ripple handling are required.
• Inverter circuitry — Energy buffering and ripple suppression in inverter DC-link and converter stages operating at elevated voltages.
• Extra-high-voltage power systems — Suitable for applications that require 550 V rated capacitors with high ripple-current endurance.
• High-ripple environments — Systems with sustained ripple currents where long-term endurance at +85°C under rated ripple is needed.

Unique Advantages

• High-voltage capability: 550 V rating enables use in extra-high-voltage industrial power designs without series stacking.
• High ripple-current handling: Significant ripple ratings at both low and high frequencies (21.6 A at 120 Hz, 30.24 A at 100 kHz) reduce thermal stress and improve system reliability under heavy AC load.
• Engineered endurance: Specified performance after 5,000 hours at +85°C under DC bias plus rated ripple current (for 500 V and 550 V parts) gives predictable lifetime for design planning.
• Robust screw-terminal packaging: Radial can with screw terminals simplifies secure electrical connections and mechanical mounting in rugged assemblies.
• Predictable leakage behavior: Leakage current limited by a defined 3√(C·V) µA or 5 mA threshold after 5 minutes at rated voltage, aiding in startup and protection circuit design.
• Regulatory and safety options: RoHS compliance and flame-retardant electrolyte options help address environmental and safety requirements.
