Key Features

• Electrical Performance — 220 µF nominal capacitance at a 10 V rated voltage with ±20% tolerance, suitable where compact bulk capacitance is required.
• Polarized Design — Aluminum electrolytic construction with defined polarity for use where polarized capacitance is required.
• High‑Temperature Endurance — Rated operating temperature from −40°C to +105°C with a specified load life of 5000 hours at +105°C.
• Ripple Current Capability — Specified ripple current: 141 mA at 120 Hz and 211.5 mA at 10 kHz, enabling use in AC ripple and decoupling environments within those limits.
• Automotive Qualification — AEC‑Q200 qualified to support automotive component requirements.
• Surface‑Mount Package — Radial, can‑style SMD package with compact footprint (L: 1.0 cm × D: 0.8 cm) and recommended land size 8.3 × 8.3 mm for high‑density PCBs.
• Regulatory Compliance — RoHS compliant (2011/65/EU and (EU)2015/863) for lead‑free application requirements.

Typical Applications

• Automotive electronics — Suited for surface‑mounted high‑density automotive PCBs where AEC‑Q200 qualification and long life at +105°C are required.
• High‑density SMD assemblies — Designed for compact circuit layouts that need 220 µF bulk capacitance in a small radial can SMD form factor.
• assemblies requiring RoHS compliance — Applicable in designs that must meet RoHS directive requirements while maintaining long‑term thermal performance.

Unique Advantages

• Long operational life: 5000 hours at +105°C specification supports extended service life in thermally demanding environments.
• Automotive‑grade qualification: AEC‑Q200 status provides traceable qualification for automotive system design requirements.
