Key Features

• Capacitance & Tolerance — 22 µF nominal with ±20% tolerance (measured at 120 Hz, 20°C).
• Voltage Rating — Rated for 450 V operation.
• Low Loss (tan δ) — tan δ = 0.08 (measured at 20°C, 120 Hz) for stable dissipation characteristics.
• Ripple Current Capability — Low-frequency ripple current 275 mA at 120 Hz and high-frequency ripple current 440 mA at 10 kHz.
• Leakage Current — 496 µA (specified after 1 minute at 20°C).
• Endurance & Temperature — Rated life 2000 hours at 85°C; operating range −40°C to 85°C.
• Package & Mounting — Chip-type surface-mount aluminum can (case size φ16 × 21.5 mm) with embossed carrier taping for automated placement; surface-mount land size 1.63 × 1.63 cm.
• AEC-Q200 Rated — Qualification for automotive-grade applications is included in the product data.

Typical Applications

• Automotive power electronics — AEC-Q200 qualification and a 450 V rating make this capacitor suitable for high-voltage automotive power rails and related power-conversion circuits.
• DC link and inverter stages — High-voltage capability combined with specified high-frequency ripple handling supports energy-storage and smoothing in inverter and converter sections.
• Industrial power supplies — Robust endurance (2000 h at 85°C) and wide temperature range enable use in industrial DC/DC and AC/DC power systems.

Unique Advantages

• High-voltage capability: 450 V rating supports designs with elevated bus voltages without adding series components.
• Measured loss characteristics: Low tan δ (0.08 at 20°C/120 Hz) provides predictable dissipation and impedance behavior for stable circuit performance.
• Broad ripple performance: Defined ripple current at both low (120 Hz) and high (10 kHz) frequencies helps ensure reliable operation across common switching and line-frequency use cases.
• Automotive-grade qualification: AEC-Q200 rating and a −40°C to 85°C operating range support use in temperature-variant vehicle environments.
• Compact SMD form factor: Chip-type aluminum can (φ16 × 21.5 mm) with embossed carrier taping enables automated assembly and a reduced board footprint compared to through-hole alternatives.
• Proven endurance: 2000 hours at 85°C provides specification-backed life performance for long-term deployments.
