LGNW6271MELC25

The LGNW6271MELC25 is a snap-in terminal aluminum electrolytic capacitor designed for general-purpose power applications. It combines high voltage capability (420 V) and a 270 µF capacitance in a smaller-sized snap-in can, offering reliable ripple-handling and long-term thermal endurance.

Engineered for high-temperature operation up to 105°C, this part is intended for designers who need robust smoothing, filtering or energy-storage components that tolerate sustained ripple current and extended endurance at elevated temperatures.

Key Features

• High Voltage & Capacitance — 270 µF rated at 420 V for bulk energy storage and filtering in high-voltage power rails.
• Snap-In Radial Can — Snap-in terminal, radial can package provides secure board mounting for power assemblies and simplifies assembly.
• High Temperature Endurance — Rated for operation up to 105°C and specified to withstand 3000 hours of applied rated ripple current at 105°C, ensuring long-term stability under thermal stress.
• Ripple Current Performance — Rated ripple current of 1.25 A at 120 Hz and 1.788 A at 100 kHz, allowing effective handling of AC ripple in switching and line-frequency circuits.
• Electrical Reliability — Capacitance tolerance ±20% and leakage current specified as I ≤ 3/√C µA after 5 minutes’ application of rated voltage at 20°C, supporting predictable performance and design margining.
• Low-Loss Characteristics — Tangent of loss angle (tan δ) up to 0.15 for 160–420 V (measured at 120 Hz, 20°C), supporting efficient energy handling in AC or pulsed environments.
• RoHS Compliant — Conforms to RoHS directive (2011/65/EU, (EU)2015/863) for regulatory compliance in assemblies.
• Compact Footprint — Smaller-sized case (one rank smaller than LGU series) with dimensions L: 2.5 × D: 3.5 cm and height seated max 2.5 cm to save chassis and board space.

Typical Applications

• Power supply smoothing and filtering — Bulk capacitance and rated ripple-handling make this capacitor suitable for smoothing DC rails and reducing AC ripple in power supplies.
• Industrial power equipment — Designed for high-temperature endurance and sustained ripple current, useful in industrial converters and power modules operating at elevated temperatures.
• Energy storage and backup circuits — 270 µF at 420 V provides compact energy storage for short-term hold-up and local decoupling in high-voltage systems.
• Switching and pulse circuits — Ripple current ratings at 120 Hz and 100 kHz support use in switching power supplies and high-frequency power stages.

Unique Advantages

• Long-duration high-temperature reliability: Specified endurance of 3000 hours at 105°C under rated ripple current reduces the need for conservative derating in hot environments.
• Measured ripple capability: Explicit ripple current values at both low and high frequencies (1.25 A at 120 Hz, 1.788 A at 100 kHz) let engineers size capacitors to actual switching and line conditions.
• Predictable electrical behavior: Clear leakage current and tan δ limits allow accurate thermal and loss budgeting in power designs.
• Space-efficient package: One rank smaller case than the LGU series and compact dimensions enable denser layouts without sacrificing voltage or capacitance.
• Regulatory readiness: RoHS compliance supports integration into assemblies intended for regulated markets.
