Engineered for industrial power supplies and ballast applications, this part emphasizes long-term reliability under elevated temperature and ripple conditions, with RoHS compliance for environmental compatibility.

Key Features

• Capacitance & Voltage — 4.7 mF rated capacitance at 50 V, tolerance −20% to +20%.
• Long-Life Endurance — Designed to withstand 5000 hours of ripple current at 105°C when operated within rated conditions.
• High Temperature Operation — Operating temperature range −40°C to +105°C for sustained high-temperature use.
• Ripple Current Performance — Rated ripple current of 2.1 A at 120 Hz and 2.415 A at 50 kHz, with frequency coefficients provided by the series specification.
• Leakage Current Specification — Leakage current limited to I ≤ 3√CV (µA) after 5 minutes at 20°C, per datasheet measurement conditions.
• Electrical Loss (tan δ) — Series specification includes tan δ limits for rated voltage; for 50 V the maximum tan δ is 0.30 (measurement at 120 Hz, 20°C).
• Package & Mounting — Radial, can-style snap-in termination for secure mounting in high-current, high-reliability power assemblies; physical size approximately L: 3.5 × D: 2.5 cm with a seated height of 1.378 inch (max).
• Polarized Design — Polarized aluminum electrolytic capacitor suitable for DC power filtering and energy storage functions.
• RoHS Compliant — Meets RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Industrial Power Supplies — Bulk filtering and ripple smoothing where long-term operation at elevated temperatures is required.
• Ballast Applications — Suitable for ballast circuits that require robust ripple-current endurance and stable capacitance over time.
• General Purpose Power Electronics — Energy storage and decoupling in general-purpose power designs that benefit from snap-in mounting and high ripple capability.
