Key Features

• Capacitance & Voltage: 470 µF rated capacitance with a 16 V working voltage and ±20% tolerance for predictable energy storage and filtering performance.
• High‑Temperature Endurance: Specified for operation from -55°C to +135°C with a 2000 hour rated life at 135°C, supporting high-temperature system requirements.
• Ripple Current Capability: Low-frequency ripple current 633.15 mA (120 Hz) and high-frequency ripple current 945 mA (10 kHz), enabling effective smoothing under varying switching conditions.
• Electrical Losses: Tan δ (DF) of 0.16 measured at 20°C, 120 Hz, and an impedance of 75 mΩ for low-loss performance in decoupling and power filtering roles.
• Leakage Current & Polarization: Leakage current specified at 225.6 µA; polarized aluminum electrolytic construction for use where polarized capacitors are required.
• Mechanical & Packaging: Compact φ10 × 16 mm radial can with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• AEC‑Q200 Rated: AEC‑Q200 listed in specifications for applications requiring automotive-grade qualification.

Typical Applications

• Automotive Electronics: Power filtering and bulk decoupling in automotive control modules and electronics that require AEC‑Q200 qualification and high-temperature operation.
• High-Temperature Power Supplies: Smoothing and hold-up in power supplies and DC–DC converters operating in elevated ambient temperatures up to +135°C.
• Industrial Power Modules: Energy storage and ripple attenuation in motor drivers, inverters, and industrial control systems exposed to wide temperature ranges.
• Embedded Systems: Decoupling and local energy storage on boards where compact radial can packages and through-hole mounting are preferred.

Unique Advantages

• Rated for +135°C operation: Enables deployment in systems with sustained high ambient temperatures while retaining capacitance and reliability for 2000 hours.
• Automotive-Grade Qualification: AEC‑Q200 listing provides confidence for vehicle electronics and other applications that demand automotive-level component qualification.
• High ripple-handling capability: Specified ripple currents at both low and high frequency (633.15 mA at 120 Hz; 945 mA at 10 kHz) support switching power environments.
• Compact, through-hole form factor: 470 µF in a φ10 × 16 mm radial can with 5 mm lead spacing offers a space-efficient solution for board-level power filtering.
• Low impedance and controlled loss: 75 mΩ impedance and tan δ of 0.16 (20°C, 120 Hz) help minimize voltage ripple and heat generation under load.
• Flexible packing options: Available in bulk (no terminal forming) or bag packing to suit assembly and procurement preferences.
