LNY2G123MSEHBN

The LNY2G123MSEHBN is an aluminum electrolytic capacitor in a screw-terminal radial can designed for high-capacitance, high-voltage applications. It delivers 12,000 µF at a 400 V rating and is specified for operation from −40 °C to +85 °C.

Built for general-purpose use and suited for equipment downsizing, this part offers sustained performance with a rated load life of 2000 hours at 85 °C when ripple current is applied. The product is RoHS compliant.

Key Features

• Capacitance & Voltage — 12,000 µF nominal capacitance with a 400 V rated voltage and ±20% tolerance (120 Hz, 20 °C).
• Screw-Terminal Mounting — Radial can with screw terminals for secure, low-resistance connections in heavy-current applications.
• High Ripple Current Capability — Rated ripple current of 26 A at 120 Hz and 36.4 A at 10 kHz to support sustained AC ripple loading.
• Operating Temperature Range — Rated for −40 °C to +85 °C operation.
• Endurance — Load life specified as 2000 hours at 85 °C with rated ripple current applied; performance validated after recovery to 20 °C.
• Leakage Current Specification — After 5 minutes at rated voltage, leakage current is specified as not more than 3√CV (µA) or 5 mA, whichever is smaller (at 20 °C).
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose equipment — Intended for use in general-purpose electronic and power equipment where a high-capacitance, high-voltage capacitor is required.
• Equipment downsizing — Suited for designs targeting reduced footprint or consolidated bulk capacitance due to its higher capacitance density within the LNY series.
• High-ripple current circuits — Applicable where sustained ripple current handling is required, supported by the specified ripple current ratings at 120 Hz and 10 kHz.
• Wide-temperature environments — Suitable for applications that must operate across a −40 °C to +85 °C temperature range.

Unique Advantages

• High-capacitance at high voltage — 12,000 µF at 400 V provides substantial energy storage capability for high-voltage designs.
• Sustained ripple handling — Ripple current ratings (26 A at 120 Hz, 36.4 A at 10 kHz) reduce stress on the capacitor under continuous AC loading.
• Proven endurance — 2000-hour load life at 85 °C under rated ripple current supports long-term reliability assessments.
• Secure screw-terminal connections — Screw terminals enable robust electrical and mechanical connection suitable for higher-current applications.
• Wide operating temperature — −40 °C to +85 °C rating enables use across a broad range of environmental conditions.
• Regulatory compliance — RoHS compliance supports regulatory needs for restricted-substance requirements.
