LGNW6121MELY35

The LGNW6121MELY35 is a polarized aluminum electrolytic capacitor in a snap‑in radial can package designed for general purpose electronic applications. It delivers 120 µF capacitance at a 420 V rating and is engineered for elevated‑temperature operation up to 105 °C.

Built to withstand extended ripple current stress, this part is specified for 3000 hours of rated ripple current application at 105 °C and is offered in a smaller case profile compared with the LGU series. It is RoHS‑compliant for environmentally conscious designs.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a 420 V rated voltage suitable for high‑voltage, polarized applications.
• High‑Temperature Endurance: Endurance specified for 3000 hours at 105 °C when subjected to D.C. bias plus rated ripple current.
• Ripple Current Performance: Rated ripple current of 810 mA at 120 Hz and 1.158 A at 100 kHz, enabling effective smoothing under AC ripple conditions.
• Operating Temperature Range: Specified for operation from −25 °C to +105 °C for the 420 V rating.
• Package & Mounting: Snap‑in radial can (snap‑in terminal type) for secure chassis or board mounting; one rank smaller case size than the LGU series.
• Tolerance & Polarization: Capacitance tolerance of −20% to +20%; polarized design for correct orientation in circuits.
• Leakage Current Standard: Leakage current meets the datasheet formula I ≤ 3/√C µA after standard voltage application (per datasheet specification).
• RoHS Compliant: Conforms to RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• General Purpose Electronics: Suitable where a polarized high‑voltage electrolytic capacitor is required for bulk energy storage or smoothing in general circuits.
• Power Conditioning: Useful for applications that require sustained ripple handling at elevated temperatures up to 105 °C.
• High‑Voltage Modules: Applicable in equipment and assemblies that need a 420 V rated electrolytic capacitor in a compact snap‑in format.

Unique Advantages

• Extended High‑Temperature Life: Specified 3000‑hour endurance at 105 °C under rated ripple current, supporting reliability in hot operating environments.
• Compact Snap‑In Form Factor: Snap‑in radial can construction with a smaller case size than the LGU series simplifies packaging in space‑constrained designs.
• High Voltage Capability: 420 V rating enables use in higher‑voltage circuits without series stacking.
• Measured Ripple Performance: Published ripple current ratings at both 120 Hz and 100 kHz provide clear guidance for thermal and ripple budgeting.
• Defined Leakage Characteristics: Leakage current specification (I ≤ 3/√C µA after standard conditioning) aids in predictable bias behavior during design.
• Regulatory Compliance: RoHS compliance supports environmentally driven procurement and manufacturing requirements.
