Key Features

• Capacitance & Voltage — 220 µF nominal capacitance rated at 35 V, with a tolerance of ±20% (measured at 120 Hz, 20°C).
• Compact SMD Can Package — 10 × 10 mm radial can configured for surface-mount use; surface mount land size L: 1.03 × W: 1.03 cm for PCB footprint planning.
• Long Life & High Temperature Endurance — Rated operational lifetime of 5000 hours at 105°C; endurance criteria specify capacitance change within ±30% and leakage current remaining at or below initial specified values after life test.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) of 0.13 at 35 V (measured at 120 Hz, 20°C) and a specified leakage current of 77 µA.
• Ripple Current Capability — Rated ripple current of 375 mA at 120 Hz and 562.5 mA at 10 kHz, supporting decoupling and filtering duties where AC ripple is present.
• Qualification & Compliance — AEC-Q200 qualified and compliant with the RoHS directive for use in regulated supply chains.
• Wide Operating Temperature — Specified operating range from −55°C to +105°C for thermal robustness in harsh environments.

Typical Applications

• Automotive Electronic Modules — Bulk energy storage and smoothing for control units and power electronics where AEC-Q200 qualification and high-temperature life are required.
• High-Density PCB Power Rails — Surface-mount can design and compact 10 × 10 mm footprint enable use on space-constrained, high-density boards for power-supply decoupling and filtering.
• Industrial and Embedded Systems — Stable performance across −55°C to +105°C and long rated life make this capacitor suitable for embedded power subsystems operating under thermal stress.

Unique Advantages

• Long-term thermal durability: 5000 hours rated life at 105°C ensures predictable performance in high-temperature applications.
• Automotive-grade qualification: AEC-Q200 status supports use in automotive designs and other reliability-critical programs.
• Compact board-level solution: 10 × 10 mm SMD can and defined PCB land pattern simplify layout on dense boards while providing 220 µF of capacitance.
• Measured ripple handling: Specified ripple currents at 120 Hz and 10 kHz provide designers with clear limits for AC stress and filtering calculations.
• Controlled electrical loss and leakage: tan δ = 0.13 (35 V) and a defined leakage current allow predictable ESR/impedance behavior in system-level designs.
• Regulatory compliance: RoHS compliance facilitates integration into regulated supply chains without additional material concerns.
