Designed to deliver reliable performance under demanding temperature and ripple conditions, this part targets audio designs that require stable capacitance, controlled leakage, and AEC‑Q200 qualification for enhanced reliability.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with a rated voltage of 25 V, tolerance ±20% (120 Hz, 20°C).
• Package & Mounting — Radial lead, can package with dimensions φ5 × 11 mm and 2 mm lead spacing for compact through‑hole placement.
• Wide Temperature Range — Operating temperature from −55°C to +105°C to support audio equipment exposed to broad environmental conditions.
• Ripple Current Performance — Low‑frequency ripple current of 58 mA (120 Hz) and high‑frequency ripple current of 116 mA (10 kHz) to handle audio supply fluctuations.
• Low Leakage — Specified leakage current of 16.5 µA for minimized DC loss in audio signal circuits.
• Endurance — Rated lifetime of 2000 hours at 105°C, with capacitance and leakage characteristics maintained per the series endurance specification.
• Qualification — AEC‑Q200 listed, supporting designs requiring that level of component qualification.

Typical Applications

• High‑grade audio equipment — Purpose‑built for premium audio components where stable capacitance and low leakage contribute to signal fidelity.
• AEC‑Q200 qualified audio systems — Suitable for audio electronics that require AEC‑Q200 component qualification for enhanced reliability.
• Temperature‑challenging audio installations — Well suited to audio devices operating across −55°C to +105°C environments.

Unique Advantages

• Compact radial can footprint — φ5 × 11 mm size with 2 mm lead spacing enables space‑efficient through‑hole layouts without sacrificing capacitance.
• Designed for audio performance — 22 µF value, low leakage (16.5 µA), and specified ripple currents support stable power and signal behavior in audio circuits.
• Wide operating range — −55°C to +105°C rating allows consistent operation across extreme ambient conditions.
• Long high‑temperature life — 2000 hours at 105°C provides predictable endurance for designs exposed to elevated temperatures.
• AEC‑Q200 qualification — Reduces the need for additional component qualification where AEC‑Q200 compliance is required.
