Key Features

• Capacitance & Tolerance — 220 µF nominal capacitance with ±20% tolerance (120 Hz, 20 °C) for predictable bulk energy storage.
• Voltage Rating — Rated at 35 V to support moderate-voltage power rails and decoupling tasks.
• High-Temperature Endurance — Rated lifetime of 5000 hours at +125 °C, supporting sustained high-temperature operation.
• Ripple Current Performance — Low-frequency ripple current of 529.3 mA (120 Hz) and high-frequency ripple current of 790 mA (100 kHz) for effective AC ripple absorption across a range of switching frequencies.
• Low Leakage — Leakage current specified at 231 µA, supporting stable performance in bias-sensitive circuits.
• Package & Mounting — Radial lead, can-style package (φ10 × 16L) with 5 mm lead spacing for through-hole assembly and straightforward PCB placement.
• AEC-Q200 Qualified — Series-level AEC-Q200 qualification indicates suitability for automotive electronics applications where component-level qualification is required.
• RoHS Compliant — Meets RoHS requirements, supporting environmentally regulated designs.

Typical Applications

• Automotive electronics — Suited for automobile electronics and heavy-duty systems that require high-temperature operation and long endurance.
• Power supply filtering — Useful for smoothing and decoupling on moderate-voltage rails where 220 µF bulk capacitance and elevated ripple handling are needed.
• Embedded and industrial modules — Fits compact through-hole designs that demand robust thermal tolerance and multi-kilohour life at elevated temperatures.

Unique Advantages

• Long high-temperature life: 5000 hours at +125 °C provides predictable aging characteristics in elevated-temperature environments.
• Dual-frequency ripple capability: Rated ripple currents at both 120 Hz and 100 kHz support filtering across low-frequency rectified supplies and higher-frequency switching sources.
• Compact radial package: φ10 × 16L can with 5 mm lead spacing allows dense through-hole placement while preserving substantial capacitance.
• Industry-level qualification: AEC-Q200 series rating and RoHS compliance give confidence for use in regulated and automotive-related designs.
• Controlled leakage: Low leakage current specification supports stable bias conditions in power and control circuits.
