Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with ±20% tolerance, rated for 16 V operation.
• Temperature Range & Endurance — Operates from -55 °C to 105 °C; specified endurance of 1,000 hours at 105 °C (for 4.5L case length).
• AEC-Q200 Qualification — AEC-Q200 rating and explicit automotive application listing support use in automotive electronic designs.
• Low Loss for Audio Use — Tangent of loss angle (tan δ) of 0.22 measured at 20 °C, 120 Hz, suitable for audio-related circuits as indicated by the UCQ series.
• Ripple Current Capability — Low-frequency ripple: 30 mA at 120 Hz; high-frequency ripple: 45 mA at 10 kHz, supporting smoothing and ripple rejection in compact circuits.
• Leakage Current — Typical leakage current 3.52 µA (after 2 minutes at rated voltage / 20 °C condition noted in datasheet specifications).
• SMD Package & Assembly — Chip-type radial can in an SMD footprint, size φ5 × 4.5 mm with recommended land pattern 5.3 × 5.3 mm; supplied in embossed carrier taping for pick-and-place.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• Automotive Electronics — Suitable for automotive modules where AEC-Q200 qualification and wide temperature range are required.
• In-vehicle Audio Equipment — UCQ series design intent for audio use and low loss characteristics make this capacitor appropriate for audio signal and power stages in automotive audio systems.
• Compact SMD Power Filtering — Small φ5 × 4.5 mm SMD package supports space-constrained board designs needing bulk or decoupling capacitance with assembly-friendly tape packaging.

Unique Advantages

• Automotive-grade Reliability: AEC-Q200 qualification and a 1,000-hour endurance at 105 °C provide specification-level confidence for vehicle electronics.
• Wide Temperature Resilience: Rated from -55 °C to 105 °C to handle harsh thermal environments commonly encountered in automotive and industrial applications.
• Audio-optimized Performance: A series focus on audio use combined with a controlled tan δ supports applications where low loss and stable AC behavior are important.
• Compact SMD Form Factor: φ5 × 4.5 mm chip package and embossed carrier taping streamline automated assembly in dense board layouts.
• Measured Ripple & Leakage Specs: Defined low- and high-frequency ripple current ratings (30 mA at 120 Hz, 45 mA at 10 kHz) and a low leakage current (3.52 µA) simplify thermal and reliability planning.
