Key Features

• Electrical Performance  33 µF nominal capacitance with a tolerance of −20% to +20%, rated at 80 V.
• Loss & Leakage  Low loss tangent with tanδ = 0.08 (measured at 20°C, 120 Hz, 80 V) and specified leakage current of 79.2 µA.
• Ripple Current Capability  Defined ripple handling of 321.6 mA at 120 Hz and 480 mA at 100 kHz for low- and high-frequency applications respectively.
• High-Temperature Endurance  Rated for operation from −40°C to +125°C with an endurance specification of 3000 hours at 125°C.
• Form Factor & Mounting  Compact radial can construction sized φ10 × 12.5 mm (L: 1.25 × D: 1.0 cm) with 5 mm lead spacing (±0.5 mm).
• Qualification & Compliance  AEC‑Q200 rated and RoHS compliant for use in regulated applications.
• Packaging  Supplied in bulk (no terminal forming) or bag packing to support flexible assembly workflows.

Typical Applications

• Automotive Electronics  Suitable for automotive electronic modules that require high-temperature operation and AEC‑Q200 qualification.
• Power Electronics  Applied where an 80 V rated capacitor with specified ripple current capability is needed for power rails and energy-storage buffering.
• Industrial Controls  Designed for heavy-duty electronics operating in elevated-temperature environments up to +125°C.

Unique Advantages

• High-temperature durability: 3000-hour endurance at +125°C provides predictable aging characteristics for thermal-stressed designs.
• AEC‑Q200 qualified: Qualification aligned to automotive electronics requirements supports use in vehicle electronic systems.
• Measured low dissipation: tanδ of 0.08 at 120 Hz (20°C, 80 V) indicates controlled dielectric losses for stable performance.
• Defined ripple performance: Specified low- and high-frequency ripple currents (321.6 mA at 120 Hz, 480 mA at 100 kHz) enable selection based on application switching frequencies.
• Compact radial package: φ10 × 12.5 mm can with 5 mm lead spacing fits space-constrained PCB layouts while providing through-hole reliability.
• Regulatory compliance: RoHS conformity supports deployment in regulated markets and product lines.
