Key Features

• Capacitance and Rating: 220 µF nominal capacitance with ±20% tolerance and a rated voltage of 160 V.
• High ripple current handling: Rated low‑frequency ripple current 1.185 A at 120 Hz and high‑frequency ripple current 2.37 A at 100 kHz for effective smoothing in power circuits.
• Long life at elevated temperature: Endurance specified at 12,000 hours at 105°C under rated conditions, supporting extended field life in harsh thermal environments.
• Thermal range: Operates from −40°C to +105°C to accommodate a wide range of ambient conditions.
• Low loss characteristics: tan δ (DF) ≤ 0.20 measured at 20°C, 120 Hz for stable dissipation factor performance.
• Leakage current: Specified leakage current 1,508 µA (per product data); datasheet provides the standard leakage formula 0.04CV + 100 µA after 1 minute at 20°C.
• Package and mounting: Radial lead, can‑style package (φ16 × 25 mm) with 7.5 mm lead spacing (±0.5 mm) for through‑hole mounting and easy PCB placement.
• Compliance and qualification: RoHS compliant and AEC‑Q200 qualified for reliability requirements in automotive and similarly demanding applications.
• Packaging options: Available in bulk (no terminal forming) or bag packing to support prototyping and production handling.

Typical Applications

• Power supplies and DC‑DC converters: Bulk and smoothing capacitor for high‑voltage rails where 160 V rating and high ripple capability are needed.
• Ballast and lighting drivers: Designed for ballast applications cited in the series datasheet, providing stable ripple filtering and long life at elevated temperature.
• Automotive power electronics: AEC‑Q200 qualification and 12,000‑hour endurance at 105°C make this capacitor suitable for automotive modules and in‑vehicle power systems.
• Industrial control and motor drives: High ripple current rating and robust temperature performance support smoothing and energy buffering in industrial power circuits.

Unique Advantages

• High ripple capacity: Dual ripple ratings at 120 Hz and 100 kHz provide clear, verifiable data for both low‑ and high‑frequency power designs.
• Extended high‑temperature life: 12,000 hours at +105°C offers documented endurance for long‑term operation in hot environments.
• Automotive‑grade qualification: AEC‑Q200 qualification supports selection for automotive and other high‑reliability applications.
• Compact radial package: φ16 × 25 mm can with 7.5 mm lead spacing balances board space efficiency and through‑hole robustness.
• Measurable electrical stability: Specified tan δ and leakage current figures enable predictable behavior for filtering and decoupling tasks.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance in modern designs.
