LNY2G182MSEF

The LNY2G182MSEF is an aluminum electrolytic capacitor in a screw-terminal radial can designed for general-purpose, high-voltage applications. With a 1.8 mF capacitance at 400 V and an operating temperature range of −40°C to +85°C, it is targeted at equipment designs that need compact bulk capacitance and reliable high-voltage performance.

Engineered for downsized equipment layouts, this LNY-series part delivers extended load life under rated ripple conditions and meets RoHS requirements for restricted substances.

Key Features

• Capacitance and Voltage — 1.8 mF (1800 µF) rated at 400 V provides substantial bulk energy storage for high-voltage circuits.
• Temperature Range — Specified for operation from −40°C to +85°C to cover a broad range of industrial and commercial environments.
• Load Life / Endurance — Rated for 2000 hours with applied ripple current at 85°C, with endurance and shelf-life criteria defined by the LNY series specifications.
• High Ripple Current Capability — 8.7 A at 120 Hz and 12.18 A at 10 kHz, supporting demanding ripple conditions in power conversion stages.
• Robust Mounting — Screw terminal radial-can package provides secure electrical and mechanical connections for high-current, high-voltage installations.
• Tolerance and Leakage — Capacitance tolerance ±20% and leakage current limits specified per LNY series (3√CV µA or 5 mA, whichever is smaller after 5 minutes at 20°C).
• Compliance — RoHS compliant (2011/65/EU, (EU)2015/863), supporting restricted-substance requirements.
• Compact Footprint — Physical footprint noted as L: 8.5 × D: 5.1 cm, suited to equipment downsizing objectives.

Typical Applications

• Industrial and Commercial Equipment — Provides bulk capacitance for general-purpose power systems where compact, high-voltage energy storage is required and equipment downsizing is a priority.
• High-Voltage Power Supplies and Converters — 400 V rating and high ripple-current capability make it suitable for bulk smoothing and energy buffering in high-voltage DC circuits.
• Power Conditioning and Energy Storage — Large capacitance supports filtering and transient energy demands in stationary power systems and power electronics.

Unique Advantages

• High Bulk Capacitance at 400 V — Enables fewer parallel components for equivalent stored energy, simplifying BOM and board layout.
• Designed for Downsized Equipment — Compact radial can footprint helps reduce system volume while maintaining required capacitance.
• Screw-Terminal Reliability — Secure mechanical and electrical connection suited to high-current, high-voltage installations.
• Validated Endurance — 2000-hour load-life rating at 85°C under ripple current provides predictable performance over extended operating periods.
• High Ripple Acceptance — Documented ripple-current specs at both low and high frequencies support designs with varied switching environments.
• RoHS Compliance — Helps meet regulatory requirements for restricted substances in deployed equipment.
