LGY1V123MELC30

The LGY1V123MELC30 is a snap‑in terminal aluminum electrolytic capacitor from Nichicon's LGY long‑life assurance series. It provides 12 mF capacitance at a 35 V rating in a radial, can-style snap‑in package designed for robust board mounting.

Engineered for industrial power applications, this part is specified to withstand prolonged ripple current at elevated temperature and is suited for use in industrial power supplies and ballast circuits where dependable, long‑term performance is required. The device is RoHS compliant and polarized for DC applications.

Key Features

• Capacitance and Voltage — 12 mF rated capacitance at 35 V with ±20% tolerance for bulk energy storage and filtering in DC power systems.
• Snap‑in Radial Can — Snap‑in terminal, radial can package simplifies secure PCB mounting for high‑reliability assemblies.
• High Temperature Rating — Rated for operation from −40°C to +105°C to support elevated‑temperature environments.
• Long‑Life Endurance — Long life assurance series specified to withstand 5000 hours of D.C. bias plus rated ripple current at 105°C; after endurance test capacitance remains within ±25% and leakage current remains at or below initial specification per datasheet.
• Ripple Current Capability — Rated ripple handling of 2.9 A at 120 Hz and 3.335 A at 50 kHz; frequency coefficients per datasheet allow designers to scale ripple ratings with frequency.
• Leakage Current Specified — Leakage current limited by the datasheet formula I ≤ 3√(C·V) (μA) after 5 minutes at 20°C, enabling predictable hold and discharge behavior in circuits.
• Regulatory Compliance — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and energy buffering where long life and sustained ripple endurance at 105°C are required.
• Ballast Circuits — Designed for ballast application use, providing stable capacitance and ripple handling over extended operation.
• General Purpose DC Filtering — Polarized bulk capacitor for smoothing and decoupling in a range of DC power systems and control electronics.

Unique Advantages

• Proven Long‑Life Specification — Specified 5000‑hour endurance at 105°C under rated ripple conditions, giving designers a clear reliability target for high‑temperature deployments.
• High Ripple Handling Across Frequency — Published ripple current values at 120 Hz and 50 kHz, plus frequency coefficients, allow accurate ripple budgeting across operating frequencies.
• Wide Operating Temperature Range — −40°C to +105°C rating supports installations exposed to broad environmental conditions.
• Secure Snap‑in Mounting — Radial snap‑in can helps ensure mechanical stability on PCBs used in industrial equipment.
• predictable leakage behavior — Datasheet leakage current formula provides a verifiable limit for charge retention and discharge design.
• Regulatory Compliance — RoHS compliance simplifies regulatory alignment for global product designs.
