Key Features

• Electrical Rating — 47 µF capacitance at a 10 V rated voltage with polarization appropriate for DC decoupling and filtering on power rails.
• Wide Temperature Range & Endurance — Operates from −55 °C to +105 °C with a rated endurance of 1000 hours at 105 °C.
• Package & Mounting — Chip type radial can SMD package designed for surface mounting on high‑density PCBs; applicable to automatic mounting machines fed with carrier tape.
• Compact Dimensions — Body size L: 5.4 × D: 6.3 mm with a maximum seated height of 5.4 mm and recommended land size L: 6.6 × W: 6.6 mm for PCB layout.
• Performance Parameters — Ripple current ratings: 46 mA at 120 Hz and 69 mA at 10 kHz; tan δ (loss tangent) for 10 V specified at a maximum of 0.24 (measurement at 120 Hz, 20 °C).
• Leakage Current & Tolerance — Capacitance tolerance ±20% (at 120 Hz, 20 °C); leakage current specification: after 2 minutes’ application of rated voltage at 20 °C, not more than 0.01CV or 3 µA, whichever is greater.
• Compliance & Qualification — AEC‑Q200 qualified and RoHS compliant, reflecting suitability for regulated automotive and industrial applications.

Typical Applications

• Automotive Electronics — Supports decoupling and filtering in electronic control units and modules where AEC‑Q200 qualification and wide temperature operation are required.
• Power Rail Decoupling — Compact 47 µF, 10 V rating and specified ripple current capabilities make it suitable for local power smoothing on low‑voltage rails.
• High‑Density Surface‑Mount Designs — Designed for surface mounting on dense PCBs and compatible with automatic carrier‑tape assembly for scalable manufacturing.
