LNY2V392MSEF

The LNY2V392MSEF is an aluminum electrolytic capacitor in a screw-terminal radial can designed for higher capacitance in space-conscious equipment. With a rated voltage of 350 V and a capacitance of 3.9 mF, it targets general-purpose electronic equipment where robust bulk capacitance and secure screw-terminal connections are required.

Key value comes from its high ripple-current capability and specified endurance: a load life of 2000 hours under ripple current at 85°C, an operating temperature range of −40°C to +85°C, and RoHS compliance for regulatory alignment.

Key Features

• Capacitance & Voltage — Rated capacitance of 3.9 mF with a rated voltage of 350 V for bulk energy storage and filtering in higher-voltage circuits.
• Screw Terminal Mounting — Radial can with screw terminals provides secure, low-resistance connections suitable for robust mechanical and electrical installation.
• High Ripple-Current Capability — Ripple current ratings of 14.8 A at 120 Hz and 20.72 A at 10 kHz support demanding AC ripple conditions specified in the datasheet.
• Endurance at Elevated Temperature — Designed for a load life of 2000 hours when subjected to rated ripple current at 85°C, as specified in the product documentation.
• Wide Operating Temperature — Specified operating range from −40°C to +85°C for use across varied thermal environments.
• Polarity and Tolerance — Polarized device with a capacitance tolerance of −20% to +20% (120 Hz, 20°C).
• Insulation and Voltage Proof — Insulation resistance exceeds 100 MΩ at DC 500 V between terminal and bracket; withstands AC 2500 V for 1 minute without abnormality (terminal to bracket), per datasheet.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Package dimension: Length 13 cm × Diameter 5.1 cm; delivered in a radial can with screw terminals.

Typical Applications

• General-Purpose Electronic Equipment — Provides bulk capacitance for power conditioning and energy storage in a wide range of industrial and electronic systems classified as general purpose.
• Space-Conscious Designs — Suited for equipment downsizing where higher capacitance must be accommodated in a compact screw-terminal can.
• High-Ripple Circuits — Applicable where elevated ripple-current handling is required, leveraging the part’s specified ripple ratings at both 120 Hz and 10 kHz.

Unique Advantages

• High Bulk Capacitance at 350 V: 3.9 mF provides substantial energy storage for filtering and decoupling in higher-voltage circuits.
• Screw-Terminal Reliability: Screw terminals offer secure mechanical and electrical connections for robust installations.
• Designed for Elevated Ripple Duty: Explicit ripple-current ratings at 120 Hz and 10 kHz reduce thermal stress under AC load conditions.
