Key Features

• High voltage rating: 450 V rated voltage suitable for high‑voltage power rails and DC link filtering.
• Capacitance and tolerance: 33 µF with ±20% tolerance at 120 Hz, 20°C for predictable filtering behavior.
• Long life at elevated temperature: Endurance specified for 10,000 hours at 105°C under DC bias plus rated ripple current.
• High ripple current capability: Low‑frequency ripple current 385 mA at 120 Hz and high‑frequency ripple current 770 mA at 100 kHz, supporting demanding ripple environments.
• Electrical loss and leakage: Tangent of loss angle (tan δ) 0.24 (measured at 20°C, 120 Hz) and leakage current listed at 694 µA.
• Temperature range: −40°C to +105°C operational range for wide environmental compatibility.
• Radial lead package: φ16 × 20L can with 7.5 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk (no terminal forming) or bag packing.
• Compliance and qualification: RoHS compliant and AEC‑Q200 qualified for use in qualified automotive and related high‑reliability systems.

Typical Applications

• Power supplies: Bulk and decoupling capacitor for high‑voltage SMPS and isolated supplies where high ripple handling and long life are required.
• Ballasts and lighting drivers: AC/DC ballast circuits that demand stable capacitance and high ripple endurance at elevated temperatures.
• Automotive electronics: High‑voltage power rails and auxiliary power systems in designs requiring AEC‑Q200 qualification and robust thermal endurance.
• Industrial power conversion: Filtering and smoothing in DC link and converter stages operating across −40°C to +105°C.

Unique Advantages

• High ripple resilience: Specified ripple currents at both low and high frequencies enable reliable operation in converters and switching environments.
• Extended high‑temperature life: 10,000‑hour endurance at 105°C provides predictable service life for long‑running equipment.
• Automotive‑grade qualification: AEC‑Q200 qualification supports use in automotive and other high‑reliability markets.
• Compact radial form factor: φ16 can with radial leads and 7.5 mm lead spacing offers a space‑efficient solution for through‑hole assemblies.
• Standards compliance: RoHS compliant to meet modern regulatory requirements for lead‑free assemblies.
• Clear electrical parameters: Specified tan δ, leakage current and tolerance values allow straightforward performance prediction during design.
