Key Features

• Capacitance & Voltage — 330 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High-temperature / Long-life — Rated for operation from −55 °C to +135 °C with endurance specified up to 3,000 hours at 135 °C.
• AEC-Q200 Qualification — Meets AEC-Q200 requirements for applications requiring recognized automotive-grade component standards.
• Ripple Current Performance — Low-frequency ripple current 931.3 mA (120 Hz) and high-frequency ripple current 1.39 A (10 kHz), allowing reliable operation under AC stress within specified limits.
• Electrical Characteristics — Low impedance of 160 mΩ and tangent of loss angle (tan δ) 0.08 measured at 20 °C, 120 Hz, supporting stable filtering performance.
• Leakage Current — Specified leakage current of 792 µA (measured per product data conditions), enabling predictable bias behavior.
• Package & Mounting — Radial-lead can (φ12.5 mm diameter, 30.5 mm length) with 5.0 mm lead spacing; available in Bulk (no terminal forming) or Bag packing for assembly flexibility.

Typical Applications

• Automotive systems — Suitable for electronics that require AEC-Q200-qualified components and operation across −55 °C to +135 °C.
• High-temperature power modules — Designed for circuits where long endurance at elevated temperature (3,000 h at 135 °C) is required.
• Through-hole radial assemblies — Fits radial-lead PCB layouts needing a φ12.5 × 30.5 mm capacitor with 5 mm lead spacing and bulk or bag packing options.

Unique Advantages

• High-temperature capability: Specified operation to +135 °C supports deployment in thermally demanding environments where standard capacitors may not suffice.
• Long endurance: 3,000-hour life at 135 °C provides predictable long-term behavior for designs requiring prolonged reliability.
• AEC-Q200-rated: Built to a recognized automotive component standard, enabling use in qualified automotive designs and other high-reliability applications.
• Robust ripple handling: Defined low- and high-frequency ripple current ratings (931.3 mA at 120 Hz, 1.39 A at 10 kHz) help maintain performance under AC stress.
• Compact radial can: φ12.5 × 30.5 mm form factor with 5 mm lead spacing offers a space-efficient through-hole solution for power and control boards.
• Predictable electrical behavior: Low impedance (160 mΩ), controlled tan δ (0.08), and specified leakage current (792 µA) support deterministic circuit design and validation.
