LGR2W470MELZ30

The LGR2W470MELZ30 from Nichicon is a snap‑in terminal aluminum electrolytic capacitor in the LGR long‑life series. It provides a 47 µF capacitance at a 450 V rated voltage in a polarized, snap‑in can package designed for general purpose applications.

Engineered for durability, this part is specified for operation from −25 °C to 105 °C and is guaranteed to withstand 10,000 hours of ripple current application at 105 °C. It is RoHS compliant for environmental compatibility.

Key Features

• Electrical Performance — 47 µF capacitance with ±20% tolerance and polarized construction, rated at 450 V for high‑voltage applications.
• Long‑Life Endurance — Designed to withstand 10,000 hours of applied ripple current at 105 °C, with post‑endurance limits defined for capacitance change, tan δ, and leakage current.
• Ripple Current Capability — Rated ripple current of 400 mA at 120 Hz and 572 mA at 50 kHz to address varying frequency conditions.
• Temperature Range — Operating range of −25 °C to 105 °C suitable for elevated‑temperature installations within the rated voltage class.
• Package & Mounting — Snap‑in, radial can package (L: 3 × D: 2.2 cm) for secure chassis or board mounting in bulk or power assemblies.
• Environmental Compliance — Compliant with RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Power Modules — Use where a 450 V, 47 µF polarized snap‑in capacitor is required and long operational life at elevated temperature is important.
• High‑Voltage DC Circuits — Suitable for circuits needing a compact, high‑voltage electrolytic with specified ripple current handling at multiple frequencies.
• Industrial Electronic Equipment — Fits designs that demand durable, RoHS‑compliant capacitors rated for extended ripple exposure at 105 °C.

Unique Advantages

• Proven Long‑Life Specification: Endurance rating of 10,000 hours at 105 °C ensures predictable performance over extended periods under rated ripple conditions.
• High Voltage Capability: 450 V rating enables use in higher‑voltage circuits without upsizing capacitance or footprint.
• Frequency‑Aware Ripple Ratings: Provided ripple current values at 120 Hz and 50 kHz allow designers to quantify thermal and lifetime effects across common operating frequencies.
• Robust Snap‑In Mounting: Radial, snap‑in can package provides a reliable mechanical connection for chassis and board installations.
• RoHS Compliant: Meets 2011/65/EU and (EU)2015/863 requirements for hazardous substance restrictions.
