Key Features

• Electrical Performance — 22 µF capacitance with a 250 V rated voltage and ±20% tolerance; polarized design for applications requiring electrolytic capacitance.
• Ripple Current Capability — Specified ripple performance of 180 mA at 120 Hz and 288 mA at 10 kHz to support AC ripple handling in power circuits.
• Reliability & Qualification — AEC-Q200 qualified with an endurance rating of 5,000 hours at 105°C; designed to meet endurance and leakage current criteria after high-temperature operation.
• Packaging & Mounting — Chip-type radial can SMD package optimized for surface mounting on high-density PCBs; compatible with automatic mounting machines fed by carrier tape.
• Temperature Range — Rated for operation from −40°C to 105°C, suitable for elevated-temperature environments encountered in automotive and industrial electronics.
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) for lead-restricted applications.
• Mechanical Dimensions & Land Pattern — Compact footprint: L 1.65 × D 1.6 cm with recommended surface-mount land size 1.63 × 1.63 cm for PCB layout and placement planning.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and −40°C to 105°C operating range make this capacitor suitable for automotive electronic modules that require robust surface-mount energy storage.
• High-density PCBs — Chip-type SMD construction and tape-feed compatibility support automated assembly of compact, densely populated boards.
• Power module filtering and smoothing — 250 V rating combined with specified ripple current ratings provides board-level capacitance for power supply filtering in industrial and vehicle systems.

Unique Advantages

• AEC-Q200 qualification: Provides a recognized reliability baseline for designs targeting automotive and ruggedized applications.
• Tape-fed assembly ready: Compatible with automatic mounting machines using carrier tape, reducing assembly time and handling complexity.
• High-temperature endurance: 5,000 hours at 105°C supports long-term operation in elevated-temperature environments, lowering replacement frequency.
• Compact SMD radial can: Small footprint and defined land pattern simplify PCB layout and enable higher component density.
• RoHS compliance: Meets lead-restriction requirements for environmentally regulated product lines.
• Defined ripple performance: Published ripple current values at 120 Hz and 10 kHz enable predictable thermal and AC behavior in power designs.
