LGN2H271MELB50

The LGN2H271MELB50 is a snap-in terminal aluminum electrolytic capacitor designed for high‑voltage, general-purpose applications. It provides 270 µF nominal capacitance at a 500 V rated voltage in a smaller-sized snap-in can configuration with radial mounting.

Engineered for elevated temperature operation, this part withstands rated ripple current for 3000 hours at 105°C and is RoHS compliant, making it suitable for designs that require long-term thermal endurance and robust snap-in mounting.

Key Features

• Capacitance & Rated Voltage — 270 µF nominal capacitance with a 500 V rated voltage and capacitance tolerance of ±20% (−20% to +20%).
• High‑Temperature Endurance — Specified to withstand 3000 hours of rated ripple current at 105°C (endurance test condition from the LGN series datasheet).
• Snap‑In Radial Can Package — Snap-in terminal type in a radial, can-style package for secure, vibration‑resistant mounting on power assemblies.
• Operating Temperature Range — Rated for operation from −25°C to +105°C for the 500 V version, matching the LGN series specification for 350–600 V parts.
• Ripple Current Capability — Rated ripple current of 1.12 A at 120 Hz and 1.602 A at 100 kHz as provided for this part.
• Leakage and Loss Characteristics — Leakage current defined by I ≤ 3/√(C) µA after 5 minutes at 20°C; tangent of loss angle (tan δ) maximum for 450–600 V group is 0.20 (measured at 120 Hz, 20°C).
• Compact Dimensioning — One rank smaller case size than LGU for space-conscious designs; physical size listed as L: 5 × D: 3 cm.
• RoHS Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose — Designed for general-purpose circuits requiring 270 µF at 500 V with snap-in mounting and high-temperature endurance.
• High-Temperature Environments — Suited for applications that require sustained operation up to 105°C and long ripple-current endurance.
• Space-Constrained Power Assemblies — One-rank smaller case size than LGU supports tighter board or chassis layouts where a radial snap-in can is preferred.

Unique Advantages

• Long Endurance at Elevated Temperature: Rated to withstand rated ripple current for 3000 hours at 105°C, supporting designs that demand prolonged high-temperature operation.
• High Voltage Capability: 500 V rating provides headroom for high-voltage circuits while maintaining 270 µF capacitance.
• Clear Ripple Current Ratings: Defined ripple current values at 120 Hz and 100 kHz help in thermal and lifetime budgeting for power circuits.
• Compact Snap‑In Packaging: Radial snap-in can with a smaller case size than LGU enables secure mounting and easier handling in assembly without sacrificing performance.
• Measurable Loss and Leakage Limits: Specified tan δ and leakage current criteria allow predictable behavior in AC and DC biased applications.
• Regulatory Compliance: RoHS compliance ensures alignment with common environmental requirements.
