Key Features

• Capacitance & Voltage — 2.2 mF nominal capacitance with a 50 V rated voltage and ±20% tolerance for consistent energy storage in audio circuits.
• Temperature Range — Rated to operate from −55°C to +105°C, supporting wide ambient conditions common in professional and consumer audio equipment.
• High-Temperature Endurance — Specified lifetime of 1000 hours at 105°C when operated at rated voltage, supporting long-term stability in demanding environments.
• Ripple Current Performance — Rated ripple current of 1.47 A at 120 Hz and 1.69 A at 10 kHz, with frequency coefficients provided in the series datasheet for design verification.
• Reliability Qualification — AEC-Q200 qualified, indicating compliance with industry reliability screening for demanding applications.
• Leakage Current Specification — Leakage defined per datasheet: after 1 minute ≤ 0.03 C·V (µA) and after 2 minutes ≤ 0.01 C·V (µA), enabling predictable leakage behavior for system design.
• Low Loss Characteristics — Tangent of loss angle (tan δ) specified for rated voltages (for 50 V the tan δ max is 0.14 at 120 Hz, 20°C), helping assess dissipation in audio circuits.
• Compact Radial Can — Radial lead package (lead spacing 7.5 mm) with dimensions L: 3.55 × D: 1.6 cm, offering a small footprint for board-level integration.
• RoHS Compliant — Meets RoHS requirements for lead-free assembly and environmental compliance.

Typical Applications
