LNY2W152MSEFBB

The LNY2W152MSEFBB is a screw-terminal aluminum electrolytic capacitor from Nichicon's LNY series, offering 1.5 mF nominal capacitance at a 450 V rating. Designed for general-purpose equipment, it provides high-voltage bulk capacitance in a radial can with secure screw-terminal connections.

Key value propositions include high-capacitance density for equipment downsizing, robust ripple-current handling, and a rated operating range to 85 °C with a 2000-hour load-life specification under rated ripple conditions.

Key Features

• Capacitance & Voltage: 1.5 mF (1500 µF) nominal capacitance at a 450 V rated voltage with ±20% tolerance (120 Hz, 20 °C).
• Screw-Terminal Power Package: Radial can with screw terminals and M5 bolt accommodation (φ51 case), providing secure, low-resistance connections for high-current applications.
• Temperature & Lifetime: Operating temperature range −40 °C to +85 °C with a specified endurance of 2000 hours at 85 °C under rated ripple current.
• Ripple Current Capability: Rated ripple current of 6.8 A at 120 Hz and 9.52 A at 10 kHz to support high-frequency and low-frequency ripple stress.
• Leakage & Insulation Characteristics: Leakage current after 5 minutes at rated voltage is limited to 3√(C·V) µA or 5 mA maximum (whichever is smaller); insulation resistance >100 MΩ at DC 500 V between terminal and bracket.
• Voltage Withstand & Reliability: Voltage proof testing at AC 2500 V for 1 minute between terminal and bracket; designed for stable performance with low-temperature impedance ratio Z(−40 °C)/Z(+20 °C) ≤ 12 for 350–450 V units.
• Form Factor: Compact radial can dimensions: L 8.5 × D 5.1 cm (φ51 × 85 mm case) to aid equipment size reduction.
• Regulatory Compliance: RoHS compliant in accordance with applicable directives.

Typical Applications

• General-purpose electronic equipment: Provides high-voltage bulk capacitance for smoothing, energy storage and decoupling in general-purpose designs.
• Equipment downsizing efforts: Higher capacitance in a compact φ51×85 mm package supports reductions in overall system volume.
• High-ripple circuits: Use in designs with significant AC ripple where rated ripple current and specified endurance at 85 °C are required.

Unique Advantages

• High-voltage bulk energy: 450 V rating combined with 1500 µF capacitance delivers substantial stored energy for high-voltage applications.
• Secure screw-terminal mounting: Screw terminals with M5 bolt accommodation enable reliable mechanical and electrical connections for higher-current paths.
• Engineered for elevated temperature operation: 85 °C rated temperature and a 2000-hour load-life under rated ripple ensures predictable aging characteristics under thermal stress.
• Measured ripple performance: Specified ripple currents at both 120 Hz and 10 kHz give designers quantifiable limits for low- and high-frequency ripple management.
• Robust electrical safety margins: Insulation resistance and voltage-proof test parameters provide defined dielectric reliability between terminal and bracket.
• RoHS compliant: Meets RoHS directive requirements for restricted substances.
