LNY2V183MSEH

The LNY2V183MSEH is an aluminum electrolytic capacitor in a screw-terminal can designed for high-capacitance, high-voltage applications. It delivers 18,000 µF at 350 V with a screw-terminal mounting style and a physical size of φ76.2 × 210 mm (L: 21 × D: 7.62 cm), making it suitable where compact, high-energy smoothing and bulk storage are required.

Targeted at general-purpose power and industrial equipment, this part supports equipment downsizing while providing robust ripple-handling and a defined load life under elevated temperature conditions.

Key Features

• High Capacitance: 18,000 µF (18 mF) rated capacitance for substantial bulk energy storage and smoothing in high-voltage DC circuits.
• 350 V Rated Voltage: Rated for 350 V operation, suitable for high-voltage power supply rails and DC link applications.
• Screw Terminal Package: Radial can with screw terminals (M5 terminal nominal for φ76.2) for secure, low-resistance connections in high-current systems.
• Ripple Current Capability: Supports 30.2 A at 120 Hz and 42.28 A at 10 kHz, enabling effective handling of AC ripple and switching noise in power conversion stages.
• Load Life and Endurance: Specified load life of 2000 hours with rated ripple current applied at 85°C; designed to meet specified capacitance, tan δ and leakage current limits after endurance testing.
• Operating Temperature Range: −40°C to +85°C for a wide range of industrial environments.
• Leakage Current Specification: After 5 minutes at rated voltage, leakage current is not more than 3√(C·V) µA or 5 mA, whichever is smaller (measured at 20°C).
• Insulation and Voltage Withstand: Insulation resistance more than 100 MΩ at DC 500 V between terminal and bracket; AC 2500 V applied for 1 minute shows no abnormality.
• RoHS Compliant: Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• High-Voltage Power Supplies: Bulk energy storage and smoothing for high-voltage DC rails in industrial power supplies and converters.
• Power Conversion and DC Link Capacitors: Supporting DC-link smoothing and ripple absorption in inverter and converter systems that require high capacitance at elevated voltages.
• Industrial Energy Storage: Intermediate energy buffering in UPS, energy management and other industrial power equipment where reliable high-capacitance elements are needed.

Unique Advantages

• Substantial bulk capacitance: 18,000 µF at 350 V provides significant stored energy for smoothing and transient support, enabling smaller arrays of capacitors in constrained designs.
• High ripple handling: Explicit ripple current ratings at both 120 Hz and 10 kHz allow designers to assess performance for line-frequency and high-frequency switching environments.
• Robust electrical isolation and withstand: Insulation resistance >100 MΩ at DC 500 V and AC 2500 V/1 min voltage proof between terminal and bracket enhance safety and reliability in high-voltage installations.
• Screw-terminal connectivity: Secure M5-compatible screw terminals provide low-impedance, mechanically robust connections for high-current applications.
• Engineered for elevated-temperature endurance: Rated for 2000 hours with rated ripple at 85°C, supporting predictable service life in demanding thermal conditions.
• Wide ambient range and low-temperature stability: −40°C to +85°C operating range and an impedance stability specification (Z(−40°C)/Z(+20°C) ≤ 12) support reliable operation across varied environments.
