LGN2G820MELY30

The LGN2G820MELY30 is an aluminum electrolytic capacitor in Nichicon’s LGN series, featuring a snap-in terminal package and a compact, smaller-sized case. It delivers 82 µF at 400 V with polarized construction and is specified for general-purpose electronic applications that require sustained ripple-current endurance at elevated temperature.

Designed to withstand extended operation under load, this part is rated for operation up to 105°C and provides ripple-current capability specified for both low and high frequencies, suitable where long-term stability under thermal stress is required.

Key Features

• Capacitance and Voltage — 82 µF rated capacitance at a 400 V working voltage for bulk energy storage in high-voltage circuits.
• Snap-In Terminal Package — Radial, can-type snap-in mounting for secure board retention and straightforward PCB assembly.
• High Temperature Endurance — Endurance specified for 3000 hours at 105°C when DC bias plus rated ripple current is applied (note: 600 V parts have different endurance limits in the series documentation).
• Ripple Current Ratings — 640 mA at 120 Hz and 915.2 mA at 100 kHz, enabling the capacitor to handle sustained ripple loads across common power frequencies.
• Operating Temperature Range — –25°C to +105°C (applicable for rated voltages in the 350–600 V category in the LGN series), supporting elevated-temperature environments.
• Leakage and Loss Characteristics — Series specification: I ≤ 3/√C µA after five minutes’ application of rated voltage at 20°C; tangent of loss angle (tan δ) limits are defined in the LGN series datasheet.
• Tolerance and Polarization — Capacitance tolerance of −20% to +20% and polarized construction.
• Compact Footprint — Smaller-sized case in the LGN family (one rank smaller than LGU), with physical dimensions approximately L: 3 × D: 2 cm and a seated height up to 1.181 inch.
• RoHS Compliant — Conforms to RoHS directives (2011/65/EU, (EU)2015/863).

Typical Applications

• General-Purpose Power Circuits — Bulk capacitance and ripple-current endurance for general-purpose electronic equipment where sustained ripple handling at elevated temperature is required.
• Power Supply Filtering — Suited for smoothing and filtering duties in high-voltage DC circuits that need long-term thermal stability.
• Industrial Electronics — Applicable where a compact, high-voltage electrolytic solution is needed with reliable performance at up to 105°C.

Unique Advantages

• Proven High-Temperature Endurance: Rated to withstand 3000 hours of DC bias plus rated ripple current at 105°C, offering predictable long-term behavior under thermal stress.
• High Ripple Capability: Specified ripple currents at both 120 Hz and 100 kHz provide design flexibility across power-frequency and higher-frequency applications.
• Space-Efficient Package: One rank smaller case than the LGU series provides a more compact footprint without sacrificing rated voltage or endurance.
• Secure Snap-In Mounting: Radial snap-in terminals enable robust PCB retention and ease of assembly for through-hole manufacturing processes.
• Quantified Leakage and Loss Parameters: Series leakage current and tan δ limits are specified, enabling reliable selection and margining in designs.
• Regulatory Compliance: RoHS compliance for use in applications requiring restricted-substance conformity.
