LNU2H822MSEJ

The LNU2H822MSEJ from Nichicon is a screw‑terminal, polarized aluminum electrolytic capacitor designed for high‑voltage industrial power applications. It provides 8.2 mF capacitance at a rated voltage of 500 V and is built for demanding environments with an operating temperature range of –40°C to 105°C.

Designed for inverter circuitry and high‑frequency regenerative circuits such as AC servomotor drives and general inverters, this part combines high voltage capability, high ripple current handling, and extended high‑temperature life to support robust power‑electronics designs. The LNU series delivers smaller size versus the LNT series while maintaining long endurance under ripple and charge‑discharge loading.

Key Features

• High voltage rating — Rated voltage 500 V for this part; the LNU series supports rated voltages up to DC525 V.
• Large capacitance — 8.2 mF capacitance suitable for energy storage and smoothing in power‑electronics applications.
• Screw‑terminal mounting — Robust radial can with screw terminals for secure electrical and mechanical connections in industrial assemblies.
• Wide temperature range — Operating range from –40°C to 105°C for stable performance in varied thermal environments.
• High ripple current capability — 20.2 A at 120 Hz and 28.28 A at 10 kHz to support heavy AC ripple and high‑frequency switching loads.
• Long high‑temperature life — Endurance specified as 5000 hours at 105°C with rated ripple current applied.
• Charge‑discharge endurance — Series specification includes qualification after 50 million charge‑discharge cycles (specified test conditions in datasheet).
• RoHS compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial power supplies: Energy smoothing and bulk storage for inverter front‑ends and high‑voltage DC bus circuits.
• Inverter drives and motor control: Support for AC servomotor regenerative voltage and motor drive regenerative loops.
• High‑frequency power electronics: Charge/discharge buffering in high‑speed switching and power conversion systems.
• General industrial equipment: DC link and filtering functions where high voltage, high ripple current and long life are required.

Unique Advantages

• High‑voltage capability: 500 V rated part (series up to DC525 V) enables use in elevated DC‑bus and inverter applications without series stacking.
• Compact LNU series sizing: Smaller physical footprint than the LNT series for space‑constrained designs while delivering comparable electrical performance.
• Robust ripple and HF performance: High ripple current ratings at both low and high frequencies help manage heat and extend service life under switching loads.
• Extended high‑temperature life: 5000 hours at 105°C endurance specification supports long‑term reliability in industrial thermal environments.
• Secure mechanical connection: Screw terminal package provides reliable clamping and low‑impedance connection for heavy current paths.
• Regulatory compliance: RoHS conformity simplifies selection for markets requiring restricted‑substance compliance.
