LGR2D102MELB45

The LGR2D102MELB45 from Nichicon is a snap-in terminal aluminum electrolytic capacitor in the LGR Long Life series. It provides 1 mF (1000 µF) capacitance at a 200 V rating in a radial, can-type snap-in package designed for general-purpose electronic equipment.

Engineered for high-temperature endurance, this part is specified for operation from −40°C to 105°C and is guaranteed to withstand 10,000 hours of ripple-current application at 105°C, offering reliable filtering and energy storage where long life and elevated-temperature performance are required. The product is RoHS compliant.

Key Features

• Capacitance and Voltage — 1 mF (1000 µF) nominal capacitance with a rated voltage of 200 V and a tolerance of ±20% (−20% to +20%).
• Long-life Endurance — Specified to meet endurance requirements after 10,000 hours of D.C. bias plus rated ripple current at 105°C, with capacitance change within ±25% and leakage current within initial specified limits.
• High Temperature Operation — Operating temperature range from −40°C to +105°C for sustained elevated-temperature performance.
• Ripple Current Performance — Rated ripple current of 2.2 A at 120 Hz and 3.3 A at 50 kHz, with frequency coefficients provided in the LGR series datasheet for scaling at other frequencies.
• Package & Mounting — Radial, can-type snap-in package intended for snap-in mounting; physical size L: 4.5 × D: 3 cm supports robust mechanical installation.
• Leakage and Loss Characteristics — Capacitance tolerance and leakage current defined per series specifications; tangent of loss angle (tan δ) limits and leakage current formula are documented in the LGR datasheet.
• Environmental Compliance — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• General-purpose electronic equipment — Suitable where a 200 V, 1 mF snap-in electrolytic capacitor is required for power filtering and bulk energy storage in general-purpose designs.
• High-temperature environments — Designed for circuits that operate up to 105°C and require proven long-life endurance under ripple current stress.
• High-ripple circuits — Applicable where elevated ripple currents at 120 Hz and higher frequencies are present, leveraging documented ripple current ratings and frequency coefficients.

Unique Advantages

• Long-life assurance: Endurance specification of 10,000 hours at 105°C provides predictable aging behavior and extended service life for sustained high-temperature applications.
• Clear ripple-current specification: Explicit ripple current ratings at 120 Hz (2.2 A) and 50 kHz (3.3 A), plus frequency coefficients in the datasheet, simplify thermal and reliability calculations.
• Robust mounting option: Snap-in radial can package offers secure mechanical retention for through-hole assemblies requiring durable connections.
• Wide operating temperature: −40°C to 105°C rating supports a broad range of operating environments without sacrificing capacitance stability.
• Regulatory compliance: RoHS conformity ensures compatibility with restricted-substance requirements.
