LGR2D471MELZ40

The LGR2D471MELZ40 from Nichicon is a snap-in terminal type aluminum electrolytic capacitor in the LGR long-life assurance series. It provides 470 µF capacitance at a 200 V rating with a snap-in radial can package and is specified for general purpose applications.

Designed for extended high-temperature operation, this capacitor is rated for continuous use from −40 °C to 105 °C and specified to withstand 10,000 hours of ripple-current application at 105 °C, making it suitable for designs demanding long-life, high-temperature ripple performance.

Key Features

• Capacitance & Voltage: 470 µF capacitance at a 200 V rated voltage, with ±20% tolerance at 120 Hz, 20 °C.
• Long-life, high-temperature endurance: Endurance specified as 10,000 hours at 105 °C under DC bias plus rated ripple current; capacitance change limited to ±25% after endurance test.
• Operating temperature range: −40 °C to 105 °C for reliable operation across a wide temperature span.
• Ripple current capability: Rated ripple currents include 1.4 A at 120 Hz and 2.1 A at 50 kHz for effective AC ripple handling; frequency coefficient data is provided in the series datasheet.
• Leakage current specification: Leakage current meets I ≤ 3√(C·V) µA (after 5 minutes at 20 °C), per series datasheet testing guidelines.
• Package & mounting: Radial, can-style snap-in package designed for snap-in mounting; physical size listed as L: 4 × D: 2.2 cm with a maximum seated height of 1.575 inches.
• Environmental compliance: RoHS-compliant (2011/65/EU, (EU)2015/863) as part of the LGR series.

Typical Applications

• General Purpose Power Designs: Intended for general purpose applications that require bulk capacitance and long-life high-temperature ripple endurance.
• Industrial and Commercial Equipment: Suited to equipment designs that benefit from extended endurance at elevated temperatures up to 105 °C.
• High‑ripple Environments: Applicable where substantial ripple current handling is needed, supported by specified ripple current values at 120 Hz and higher frequencies.

Unique Advantages

• Proven long-life performance: Specified 10,000-hour endurance at 105 °C under rated conditions, providing predictable lifespan for maintenance planning.
• High-temperature reliability: Rated operation to 105 °C with defined post-test limits for capacitance, tan δ, and leakage current to help maintain system stability.
• Clear electrical limits: Leakage current formula and tan δ limits are published in the series datasheet for design verification and QA testing.
• Robust ripple handling: Frequency-specific ripple current ratings (e.g., 1.4 A at 120 Hz, 2.1 A at 50 kHz) let you size capacitors to real-world AC conditions.
• Snap-in radial package: Snap-in mounting simplifies chassis assembly and secure mechanical retention in high-vibration or high-density enclosures.
• RoHS compliant: Meets RoHS directives (2011/65/EU, (EU)2015/863), supporting regulatory and environmental requirements.
