Key Features

• Capacitance & Voltage — 2200 μF (2.2 mF) nominal capacitance with a rated voltage of 10 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• Low Impedance Chip Type — Chip‑type, low impedance construction optimized for surface‑mount use on high‑density PCBs.
• Ripple Current Handling — Low‑frequency ripple current 550 mA (120 Hz) and high‑frequency ripple current 1.1 A (10 kHz) to support smoothing and decoupling in power rails.
• Loss Characteristics — Tangent of loss angle (tan δ) 0.21 measured at 20°C, 120 Hz, 10 V (accounting for high capacitance correction).
• Leakage Current — Specified leakage current of 220 μA.
• Temperature & Endurance — Operating range −55°C to 105°C with endurance of 5000 hours at 105°C under rated voltage.
• Package & Mounting — φ12.5 × 13.5 mm chip can, surface mount radial SMD case, supplied in embossed carrier taping for automated placement.
• Qualification & Compliance — AEC‑Q200 rating and RoHS‑compliant.
• Polarized — Polar capacitor suitable for DC power applications.

Typical Applications

• Automotive electronic modules — AEC‑Q200 qualification and −55°C to 105°C operation make it suitable for vehicle ECUs and power management modules.
• Power supply filtering — 2.2 mF at 10 V with high ripple current specifications supports bulk smoothing and rail decoupling on DC power lines.
• Surface‑mount, high‑density PCBs — Chip can format and embossed carrier taping enable automated placement in compact assemblies.

Unique Advantages

• AEC‑Q200 qualified: Enables use in applications that require an industry standard automotive component qualification.
• High ripple capability: Defined low‑ and high‑frequency ripple current ratings (550 mA at 120 Hz, 1.1 A at 10 kHz) reduce thermal stress in power circuits.
• Wide temperature and long endurance: −55°C to 105°C rating with 5000 hours endurance at 105°C supports long life under elevated temperature conditions.
• Compact SMD can: φ12.5 × 13.5 mm package delivers high capacitance in a space‑efficient chip format for dense board layouts.
• Controlled loss and leakage: Measured tan δ of 0.21 and specified leakage current of 220 μA provide predictable behavior for power integrity design.
• Assembly friendly packaging: Embossed carrier tape format facilitates automated pick‑and‑place on production lines.
