LGR2W101MELA40

The LGR2W101MELA40 is an aluminum electrolytic capacitor in a snap-in terminal, radial can package from Nichicon's LGR Long Life Assurance series. It is a polarized, high-voltage unit rated 450 V with 100 µF capacitance and designed for general-purpose applications.

Engineered for elevated operating temperatures, this part delivers extended ripple endurance and long-term stability, with specified performance after 10,000 hours of ripple-current application at 105°C. It is RoHS-compliant.

Key Features

• Capacitance & Tolerance — 100 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C).
• High Voltage Rating — Rated voltage: 450 V DC, suitable where high-voltage polarized electrolytic capacitance is required.
• Long-Life Endurance — Long Life Assurance series specified to withstand 10,000 hours of DC bias plus rated ripple current at 105°C; capacitance change within ±25% after endurance test.
• Operating Temperature — Specified operating range: −25°C to +105°C to support elevated-temperature environments.
• Ripple Current Performance — Rated ripple current of 640 mA at 120 Hz and 915.2 mA at 50 kHz for this part; frequency coefficient table available for other frequencies.
• Electrical Stability — For 450 V products, tan δ (max.) is 0.20 at 120 Hz, 20°C; impedance stability at low temperature defined in datasheet.
• Package & Mounting — Radial, can-style snap-in terminal package for secure PCB mounting and mechanical retention.
• Polarized Design — Electrolytic, polarized capacitor intended for DC applications.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Dimension: length 4.0 cm × diameter 2.5 cm (as specified for this part).

Typical Applications

• General-purpose high-voltage circuits — Provides 450 V, 100 µF polarized capacitance where general-purpose electrolytic parts are required.
• Environments requiring elevated-temperature endurance — Specified for continuous operation up to 105°C with 10,000-hour ripple endurance for long-term reliability.
• PCB-mounted bulk capacitance — Radial snap-in package suited to board-level mounting where secure mechanical retention is needed.

Unique Advantages

• Extended ripple-life specification — Rated to survive 10,000 hours of DC bias plus rated ripple current at 105°C, helping maintain capacitance and leakage characteristics over long duty cycles.
• High-voltage capability — 450 V rating supports higher-voltage DC bus and power circuits without requiring series stacking of lower-voltage parts.
• Measured ripple performance — Published ripple current values (640 mA at 120 Hz; 915.2 mA at 50 kHz) allow designers to size components against expected AC stress.
• Clear electrical limits — Datasheet specifies tan δ limits and low-temperature impedance ratios for 400–450 V products, enabling predictable behavior across temperature and frequency.
• RoHS compliance — Meets RoHS (2011/65/EU, (EU)2015/863) environmental requirements for lead-free processes and regulatory alignment.
• Snap-in radial package — Facilitates secure PCB installation and mechanical stability in assemblies.
