LGC2H221MELC25

The LGC2H221MELC25 is a snap‑in terminal, large‑can aluminum electrolytic capacitor from Nichicon's LGC series. It delivers 220 µF at a 500 V rating in a compact case that is one rank smaller than the LGX series, making it suited for equipment downsizing.

This polarized, radial can capacitor is designed for general‑purpose applications that require high working voltage, long‑life performance at elevated temperature, and snap‑in mounting for secure PCB installation.

Key Features

• Rated Capacitance and Voltage — 220 µF capacitance at a 500 V rated voltage for high‑voltage bulk energy storage in a single component.
• Compact Snap‑in Package — Radial, can‑type snap‑in terminals simplify PCB mounting; physical size is 35 × 25 mm (φD × L) / L: 2.5 × D: 3.5 cm.
• High Temperature Long Life — Endurance rated 5000 hours at 105°C under DC bias plus rated ripple current, supporting extended service life in hot operating environments.
• Operating Temperature Range — Specified for –40°C to +105°C to accommodate a wide range of ambient conditions.
• Ripple Current Capability — Rated ripple currents of 1.2 A at 120 Hz and 1.716 A at 50 kHz; frequency coefficient data in the series supports higher allowable ripple at increased frequency.
• Electrical Stability and Reliability — Leakage current defined as I ≤ 3√(C·V) µA after 5 minutes at 20°C; tan δ ≤ 0.25 (120 Hz, 20°C); impedance stability Z(–25°C)/Z(+20°C) ≤ 8 (120 Hz).
• Tolerance and Polarization — Capacitance tolerance ±20% (120 Hz, 20°C); polarized construction.
• RoHS Compliant — Conforms to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Equipment — Intended for general‑purpose applications requiring a 500 V, 220 µF snap‑in aluminum electrolytic capacitor.
• Equipment Downsizing — One rank smaller case than LGX makes it suitable where reduced component footprint is a priority.
• PCB‑Mounted Power Assemblies — Snap‑in radial can with PC board hole dimensions provided for secure mounting in PCB assemblies.

Unique Advantages

• Compact high‑voltage solution: 220 µF at 500 V in a smaller can than the LGX series enables space‑conscious high‑voltage designs.
• Long life at elevated temperature: 5000 hours endurance at 105°C under rated conditions provides predictable aging and maintenance planning.
• Measurable ripple performance: Specified ripple current values at 120 Hz and 50 kHz with series frequency coefficients allow engineers to size capacitors based on actual ripple conditions.
• Defined electrical limits: Clear leakage current formula (I ≤ 3√CV), tan δ limit, and low‑temperature impedance specification help in validating circuit margins.
• Ease of assembly: Snap‑in terminals and standardized board hole dimensions facilitate robust mounting and repeatable assembly processes.
• Regulatory compliance: RoHS conformity reduces material compliance work for product teams.
