Key electrical traits include polarized construction, defined ripple current ratings, and a lifetime rating at elevated temperature.

Key Features

• Capacitance & Voltage: 22 µF nominal capacitance with a rated voltage of 25 V and tolerance of ±20% for bulk decoupling and energy storage tasks.
• Low Impedance: Specified impedance of 760 mOhm to support low-impedance filtering and smoothing on power rails.
• Temperature Range & Endurance: Operates from −55 °C to +105 °C with a rated lifetime of 2000 hours at 105 °C, giving defined long-term performance at elevated temperatures.
• Ripple Current Ratings: 150 mA at 120 Hz and 225 mA at 10 kHz, enabling predictable AC ripple handling across low and high-frequency domains.
• Package & Mounting: Chip-type, radial can SMD designed for surface mounting on high-density PCBs and compatible with automatic mounting machines fed with carrier tape.
• Compliance & Qualification: RoHS compliant and AEC-Q200 qualified, addressing regulatory and automotive reliability requirements.
• Polarized Construction: Polarized aluminum electrolytic design for conventional DC supply decoupling and smoothing.
• PCB Land Size: Recommended surface-mount land size 5.3 × 5.3 mm to support reliable soldering and placement.

Typical Applications

• Automotive electronics: Used for power-rail smoothing and decoupling in automotive control modules and electronic subsystems where AEC-Q200 qualification is required.
• Power supply filtering: Provides bulk filtering and ripple attenuation on 25 V rails with defined ripple current capability at both low and high frequencies.
• High-density PCB designs: Chip-type SMD format supports placement on compact, automated-assembly boards for consumer and industrial products requiring stable capacitance in a small footprint.

Unique Advantages

• AEC-Q200 Qualified: Explicit qualification for applications that require automotive-grade component reliability.
• Temperature-rated endurance: Specified lifetime of 2000 hours at 105 °C establishes predictable performance under elevated thermal stress.
• Dual-frequency ripple handling: Separate ripple current specifications at 120 Hz and 10 kHz provide clarity for designers addressing both bulk and higher-frequency noise.
• Automated assembly ready: Chip-type SMD can and carrier-tape compatibility simplify automated placement and reduce assembly cycle complexity.
• Regulatory compliance: RoHS compliance supports environmental and regulatory requirements for modern electronics production.
