This radial lead, polarized capacitor delivers 330 µF at 160 V with a rated operating temperature range of −40 °C to +105 °C and 12,000 hours load life at 105 °C, providing a compact, robust energy-storage solution for industrial and automotive-grade designs.

Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with a rated voltage of 160 V and tolerance of −20% to +20%.
• High Ripple Current Capability — Low-frequency ripple current 1.51 A (120 Hz) and high-frequency ripple current 3.02 A (100 kHz), supporting high-stress power applications.
• Long Endurance — Specified for 12,000 hours at +105 °C under rated voltage plus ripple current, enabling extended field life in continuous-use systems.
• Electrical Losses — Tangent of loss angle (tan δ) max 0.20 measured at 20 °C, 120 Hz, providing predictable impedance and dissipation characteristics.
• Leakage Current — Specified leakage current of 2,212 µA for the part as listed, and series leakage formula available in the datasheet for verification.
• Compact Radial Can — Physical size φ16 × 30.5 mm (3.05 × 1.6 cm), radial lead spacing 7.5 mm (±0.5 mm), suitable for through-hole assemblies.
• AEC-Q200 Qualified — Series-level AEC-Q200 qualification for components required in automotive-related designs.
• RoHS Compliant — Meets RoHS requirements for environmental compliance.
• Packaging Options — Available in bulk (no terminal forming) and bag packing for flexible handling and assembly processes.

Typical Applications

• Power Supplies and Ballasts — Used for bulk filtering and energy smoothing where high ripple current capability and long life at elevated temperatures are required.
• Automotive Electronics — Suitable for automotive system use where AEC-Q200 qualification and wide operating temperature (−40 °C to +105 °C) are needed.
• Industrial Power Modules — Designed for continuous-duty industrial converters and modules that demand sustained ripple handling and endurance.

Unique Advantages

• High ripple-current handling: 1.51 A at 120 Hz and 3.02 A at 100 kHz deliver reliable performance in high-stress power circuits.
• Long rated life at high temperature: 12,000 hours at +105 °C supports designs requiring extended mean-time-to-failure and reduced maintenance.
• Automotive-grade qualification: AEC-Q200 series qualification aligns this capacitor with automotive reliability requirements.
• predictable dissipation characteristics: tan δ = 0.20 (20 °C, 120 Hz) provides consistent impedance behavior for filter and decoupling design.
• Compact, through-hole form factor: φ16 × 30.5 mm can with 7.5 mm lead spacing provides a space-efficient, serviceable option for through-hole assemblies.
• Regulatory compliance: RoHS compliance ensures conformity with modern environmental restrictions.
