Key Features

• Electrical Performance: 3.9 µF capacitance with ±20% tolerance and 400 V rated voltage for high‑voltage filter and decoupling tasks.
• Loss and Leakage: tan δ of 0.25 measured at 20°C, 120 Hz, and measured leakage current of 162.4 µA for predictable dissipation and standby loss characteristics.
• Ripple Handling: Low‑frequency ripple current 39 mA (120 Hz) and high‑frequency ripple current 65.13 mA (10 kHz) for AC ripple suppression across a range of switching frequencies.
• Temperature & Endurance: Rated for operation from −40°C to 105°C with an endurance rating of 3000 hours at 105°C, supporting long lifetimes in elevated thermal environments.
• Automotive Qualification: AEC‑Q200 rated, addressing requirements for automotive and similarly demanding applications.
• Compact SMD Package: φ10 × 10L chip can style (radial, can − SMD) packaged in embossed carrier taping for efficient pick‑and‑place handling; surface mount land size 10.3 × 10.3 mm.
• Polarized Device: Polar capacitor suitable for DC applications where polarity is defined.

Typical Applications

• Automotive electronic modules: Use in electronic control units and power modules where AEC‑Q200 qualification and 400 V rating are required.
• High‑voltage filtering and decoupling: Smoothing and energy storage in circuits that require compact, high‑voltage SMD capacitors within −40°C to 105°C operating range.
• Space‑constrained assemblies: Compact φ10 × 10L can style for designs that need automated placement and reduced board footprint.

Unique Advantages

• AEC‑Q200 automotive grade: Provides specified qualification for use in automotive and other demanding applications where component qualification is required.
• High‑voltage capability in an SMD chip: 400 V rating enables use in higher‑voltage rails while maintaining a compact package.
• Long thermal endurance: 3000 hours at 105°C supports extended field life in elevated temperature environments.
• Measured ripple and leakage figures: Published ripple current values at 120 Hz and 10 kHz plus measured leakage current (162.4 µA) allow designers to size and model thermal and standby behavior accurately.
• Pick‑and‑place friendly packaging: Embossed carrier taping streamlines automated assembly of SMD can‑style capacitors.
