LGR2E181MELZ30

The LGR2E181MELZ30 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package. It delivers 180 µF at 250 V with a compact φ22 × 30 mm can and is supplied in tray packing for mass production.

Designed for general-purpose applications, this Nichicon LGR series part combines high ripple-handling capability, long-life assurance at elevated temperature, and RoHS compliance to support reliable operation in demanding environments.

Key Features

• Capacitance & Voltage — 180 µF rated capacitance with a 250 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• High-temperature Long Life — Long life assurance with endurance specified for 10,000 hours at 105°C when subjected to rated ripple current and DC bias.
• Ripple Current Performance — Rated ripple current of 900 mA at 120 Hz and 1.35 A at 50 kHz; frequency coefficients for the 200·250 V category are provided in the series datasheet (e.g., 1.00 at 120 Hz, 1.50 at 50 kHz or more).
• Polarized Aluminum Electrolytic — Polarized construction suitable where polarized capacitors are required; leakage current and tan δ limits are specified in the datasheet.
• Robust Operating Range — Operating temperature range from −40°C to +105°C with endurance and shelf-life specifications documented for reliability.
• Snap-in Radial Can Package — Snap-in terminal type in a radial can (φ22 × 30 mm) for secure mechanical mounting and efficient assembly; supplied in tray packing for mass-production workflows.
• RoHS Compliant — Meets RoHS directives as indicated in the product description and series documentation.

Typical Applications

• General-purpose — For designs that require a 180 µF, 250 V aluminum electrolytic capacitor with long-life performance at 105°C.
• General-purpose — Appropriate where polarized capacitors with specified ripple current capability and ±20% tolerance are needed.
• General-purpose — Intended for production environments that benefit from tray-packed, snap-in radial can components for streamlined assembly.

Unique Advantages

• Long operational life: Endurance rated at 10,000 hours at 105°C provides documented longevity under rated ripple and bias conditions.
• High ripple capacity: Measured ripple current ratings (900 mA at 120 Hz, 1.35 A at 50 kHz) and published frequency coefficients allow designers to size capacitors against expected ripple loads.
• Compact, assembly-friendly package: φ22 × 30 mm snap-in radial can simplifies mechanical mounting and is supplied in tray packing for high-volume assembly.
• Wide operating temperature: −40°C to +105°C operating range supports use in elevated-temperature installations covered by the LGR series specifications.
• Standards and material compliance: RoHS compliance is specified for environmental/materials requirements.
