Overview of LGNW6151MELY40 – Aluminum Electrolytic Capacitor, Snap-In, 105°C

The LGNW6151MELY40 is a polarized aluminum electrolytic capacitor in a radial can with snap-in terminals, designed for general-purpose power applications. It delivers 150 µF capacitance at a 420 V rating and is built for elevated operating temperatures up to 105°C.

Engineered for durability, this smaller-sized snap-in capacitor withstands 3000 hours of rated ripple current at 105°C and offers robust ripple-handling capability across both low and high frequency ranges, making it suitable for high-voltage, thermally demanding environments.

Key Features

  • Capacitance & Voltage — 150 µF nominal capacitance with a 420 V rated voltage for high-voltage power circuits.
  • Temperature Performance — Rated for operation from −25°C to 105°C, supporting demanding thermal conditions.
  • Endurance at Elevated Temperature — Designed to withstand 3000 hours of rated ripple current application at 105°C, maintaining capacitance, dissipation factor, and leakage within specified limits.
  • Ripple Current Capability — Rated ripple current of 840 mA at 120 Hz and 1.201 A at 100 kHz for effective smoothing and filtering across frequency ranges.
  • Compact Snap-In Package — Radial can with snap-in terminals for secure mounting; one rank smaller case size compared to LGU series variants.
  • Tolerance & Polarization — ±20% capacitance tolerance and polarized design for correct-polarity installation.
  • RoHS Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
  • Physical Size — Body dimensions approximately L: 4 × D: 2 cm for space-conscious designs.

Typical Applications

  • General-purpose power filtering — Bulk smoothing and energy storage in high-voltage power supplies where 420 V ratings and high ripple capability are required.
  • Industrial power electronics — Use in equipment that operates in elevated temperature environments, leveraging the 105°C endurance and 3000-hour ripple-life specification.
  • High-voltage DC link and smoothing — Suitable for high-voltage circuits needing stable capacitance and reliable ripple handling across low and high frequencies.

Unique Advantages

  • Extended high-temperature endurance — 3000 hours at 105°C under rated ripple current preserves electrical characteristics over long operating periods.
  • High-voltage capability — 420 V rating supports designs that require reliable operation at elevated DC voltages.
  • Broad ripple performance — Specified ripple current values at 120 Hz and 100 kHz enable effective filtering across common power-conversion frequencies.
  • Space-efficient form factor — One rank smaller case size than comparable LGU parts helps reduce enclosure footprint while maintaining performance.
  • Secure snap-in mounting — Radial snap-in terminals provide robust mechanical retention for through-hole assemblies.
  • Regulatory compliance — RoHS-compliant construction supports environmental and regulatory requirements.

Why Choose LGNW6151MELY40?

LGNW6151MELY40 is positioned for designers who need a reliable, high-voltage electrolytic capacitor that balances compact packaging with sustained performance at elevated temperatures. Its 420 V rating, 150 µF capacitance, and 3000-hour ripple endurance at 105°C make it a practical choice for demanding power-filtering and energy-storage roles in general-purpose and industrial applications.

This part is well suited for engineers seeking a durable snap-in aluminum electrolytic solution that offers verified ripple performance, RoHS compliance, and a reduced case size compared to related series, helping to simplify BOM decisions and long-term product support.
