LGR2D122MELB50

The LGR2D122MELB50 is a snap-in terminal aluminum electrolytic capacitor from Nichicon's LGR long-life series. It delivers 1.2 mF capacitance at a 200 V rating in a radial, can-style snap-in package and is RoHS compliant.

Designed for general-purpose electronic applications, this capacitor is specified for extended operation at elevated temperature with defined endurance and ripple-current performance, making it suitable where long life and thermal reliability are required.

Key Features

• Capacitance & Voltage — 1.2 mF capacitance rated at 200 V for bulk energy storage where this value is required.
• Snap-in Terminal Package — Radial, can-style snap-in mounting for board retention and secure mechanical installation.
• High-Temperature, Long-Life Specified — Rated for operation to 105°C with endurance characterized as 10,000 hours at 105°C under DC bias plus rated ripple current.
• Ripple Current Capability — Rated ripple current of 2.3 A at 120 Hz and 3.45 A at 50 kHz, with frequency coefficients specified in the series datasheet.
• Operating Temperature Range — Specified for –40°C to +105°C operation for the 200 V rating.
• Endurance and Stability — After the 10,000 hour endurance test at 105°C, capacitance change is specified within ±25%, tan δ ≤250% of initial, and leakage current ≤ initial specified value.
• Capacitance Tolerance — ±20% at 120 Hz, 20°C.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).
• Physical Size — Package dimensions approximately L: 5 cm × D: 3 cm with a maximum seated height of 1.969 inch as specified.

Typical Applications

• General-purpose electronic circuits — For designs that require a 200 V, 1.2 mF snap-in aluminum electrolytic capacitor with long-life specification.
• High-temperature environments — Where operation up to 105°C and a defined 10,000-hour endurance are required.
• High ripple-current situations — Applications that demand sustained ripple current handling up to the specified 2.3 A (120 Hz) and 3.45 A (50 kHz) ratings.

Unique Advantages

• Long-life qualification: Endurance characterized for 10,000 hours at 105°C with specific post-test limits on capacitance, tan δ, and leakage current, enabling predictable aging behavior.
• High-temperature capability: Rated to operate across –40°C to +105°C (for 200 V), supporting designs that encounter elevated ambient or internal temperatures.
• Clear ripple-current specifications: Explicit ripple current ratings at 120 Hz and 50 kHz, plus series frequency coefficients, allow designers to size components against application-specific ripple profiles.
• Robust mechanical mounting: Snap-in radial can package offers secure board attachment for applications requiring reliable physical retention.
• Regulatory compliance: RoHS conformity is documented, supporting regulatory requirements for lead-free assemblies.
• Traceable performance limits: Datasheet-defined limits for leakage, tan δ, and impedance stability provide verifiable criteria for design acceptance and qualification.
