LGY1E153MELC30

The LGY1E153MELC30 is a snap‑in terminal aluminum electrolytic capacitor designed for long‑life, high‑temperature operation. Configured as a 15,000 µF, 25 V polarized can, it targets industrial power applications and ballast circuits where dependable bulk energy storage and ripple filtering are required.

Built for sustained operation at elevated temperatures, this RoHS‑compliant device delivers extended endurance and measurable ripple handling for demanding general‑purpose power designs.

Key Features

• Capacitance & Voltage — 15,000 µF nominal capacitance at a 25 V rated voltage, with a tolerance of ±20% (120 Hz, 20°C).
• Long‑life Endurance — Rated for 5,000 hours of operation at 105°C with DC bias plus rated ripple current; meets the LGY series long life assurance specification.
• Wide Operating Temperature — Specified for −40°C to +105°C operating temperature range for use in high‑temperature environments.
• Ripple Current Capability — Rated ripple currents include 2.9 A at 120 Hz and 3.335 A at 50 kHz, with frequency coefficients defined in the datasheet.
• Leakage Current Specification — Leakage current limited to I ≤ 3√(C·V) µA after 5 minutes at 20°C, per the datasheet condition.
• Loss Tangent (tan δ) — tan δ specified for 25 V as a maximum of 0.40 (measured at 120 Hz, 20°C).
• Package & Mounting — Radial, snap‑in can package for secure board mounting (snap‑in terminal type) and compact footprint: approximately L 3 × D 3.5 cm and seated height up to 1.181 inch.
• Compliance — RoHS compliant in accordance with the LGY series declaration.

Typical Applications

• Industrial Power Supplies — Bulk energy storage and output filtering where long life at elevated temperature improves system reliability.
• Ballasts — Suited for ballast circuits that require stable capacitance and ripple handling over long operating periods at 105°C.
• General Purpose Power Systems — Use in general purpose DC link, smoothing, and filtering applications that benefit from high capacitance in a snap‑in package.

Unique Advantages

• Proven long‑life rating — 5,000 hours at 105°C ensures predictable end‑of‑life behavior for designs with sustained high‑temperature ripple stress.
• High capacitance density — 15,000 µF in a compact radial, snap‑in can reduces the number of components required for bulk storage on the power rail.
• Measurable ripple performance — Rated ripple currents provided for both low and high frequency (120 Hz and 50 kHz) simplify thermal and reliability calculations.
• Wide operating range — −40°C to +105°C rating supports operation across harsh temperature environments common in industrial equipment.
• Controlled leakage and dissipation — Leakage current and tan δ specifications allow deterministic design of bleed paths and loss budgets.
• RoHS compliance — Meets RoHS requirements for environmental and regulatory conformity.
