LGR2E221MELA25

The LGR2E221MELA25 is a Nichicon LGR series aluminum electrolytic capacitor with a snap-in terminal design, rated at 220 µF and 250 V. It is built for general-purpose applications that require high-voltage capacitance with long-life assurance and RoHS compliance.

This snap-in, radial can package offers high operating temperature endurance and measurable ripple performance, making it suitable where reliable bulk capacitance and sustained ripple handling at elevated temperatures are required.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance at a rated voltage of 250 V, with a tolerance of −20% to +20%.
• Snap-in Radial Can Package — Snap-in terminal mounting for secure board attachment; package described as radial, can - snap-in.
• High Temperature Long Life — Rated operating temperature range −40 °C to +105 °C with long life assurance of 10,000 hours at 105 °C.
• Ripple Current Capability — Rated ripple current of 1 A at 120 Hz and 1.5 A at 50 kHz; frequency coefficient for 200/250 V shows 1.00 at 120 Hz and 1.50 at 50 kHz.
• Electrical Loss and Leakage — Datasheet specifies tangent of loss angle (tan δ) maximum of 0.15 for 200–400 V range; leakage current follows I ≤ 3√(C·V) µA after 5 minutes at 20 °C per series specification.
• Polarized Design — Polarized electrolytic type with markings consistent with the LGR series sleeve printing.
• Compact Footprint — Physical size documented as L: 2.5 × D: 2.5 cm with a maximum seated height of 2.5 cm for space-conscious designs.
• Regulatory — RoHS compliant as stated in product data and series guidance.

Typical Applications

• General-purpose power filtering — Bulk smoothing and decoupling in power supplies where 250 V ratings and long life at elevated temperature are required.
• Industrial control equipment — Energy storage and ripple absorption in industrial electronics operating in environments up to 105 °C.
• High-voltage electronics — Applications requiring 200–400 V class capacitance with reliable leakage and loss characteristics.

Unique Advantages

• Long operational life: 10,000 hours at 105 °C provides predictable aging and maintenance planning for long‑life installations.
• High-temperature capability: Rated to +105 °C, enabling use in hot operating environments without derating of the specified lifetime.
• Frequency-aware ripple handling: Specified ripple currents at 120 Hz and 50 kHz, with published frequency coefficients, allow engineers to size capacitors for actual operating frequencies.
• Clear electrical limits: Loss tangent and leakage current limits defined by the series datasheet support thermal and reliability calculations.
• Secure mounting: Snap-in, radial can construction simplifies board assembly for robust mechanical retention in high-current, high-vibration environments.
• RoHS compliance: Meets environmental directive requirements noted for the LGR long-life series.
