The part is optimized for long-life performance under elevated temperature and ripple stress, making it suitable for general-purpose power filtering and ballast applications.

Key Features

• Capacitance & Voltage — 15 mF rated capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C.
• Long‑life High‑Temperature Endurance — Long life assurance withstanding 5000 hours of DC bias plus rated ripple current at 105°C; capacitance change remains within ±25% after endurance testing.
• High Ripple Current Capability — Rated ripple current of 3.8 A at 120 Hz and 4.37 A at 50 kHz, with frequency coefficients for ripple current (50 Hz: 0.88, 60 Hz: 0.90, 120 Hz: 1.00, 300 Hz: 1.07, ≥1 kHz: 1.15).
• Wide Operating Temperature — Specified for operation from −40°C to +105°C to support demanding thermal environments.
• Electrical Characteristics — Leakage current conforms to I ≤ 3√CV (μA) after 5 minutes at 20°C; tangent of loss angle (tan δ) maximum for 50 V is 0.30.
• Package & Mounting — Radial can with snap‑in terminals for secure board mounting and robust mechanical retention.
• Polarized Design — Polarized electrolytic capacitor for DC filtering and energy storage applications.
• RoHS Compliant — Compliant to the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Used for bulk filtering and smoothing where long life at elevated temperatures and sustained ripple handling are required.
• Ballast Circuits — Suitable for ballast applications as indicated by the LGY series specification for dependable performance under continuous ripple stress.
• General Purpose Power Filtering — Effective for DC rail decoupling and energy storage in equipment that requires a polarized electrolytic with high ripple capability and extended endurance.

Unique Advantages

• Proven Long‑Life Endurance: 5000 hours at 105°C with rated ripple current provides quantifiable lifespan data for reliability planning.
• High Ripple Handling: Measured ripple current ratings (3.8 A at 120 Hz, 4.37 A at 50 kHz) and frequency coefficients help designers size caps for real-world AC stress conditions.
• Wide Temperature Range: −40°C to +105°C operation supports deployment in thermally challenging industrial environments.
• Clear Electrical Limits: Leakage current formula and tan δ specification provide verifiable acceptance criteria for incoming inspection and design verification.
• Secure Snap‑in Mounting: Radial, can-style snap‑in termination simplifies PCB retention and mechanical stability in high‑vibration installations.
• Regulatory Compliance: RoHS compliance supports use in regions and products requiring restricted substance adherence.
