UCZ2A301MNQ1MS

The UCZ2A301MNQ1MS is a chip-type aluminum electrolytic capacitor designed for high-reliability, high-temperature surface-mount applications. It delivers 300 µF at a 100 V rating in a compact radial can SMD package and is engineered for operation from -40 °C to +125 °C.

Built for demanding environments, this part combines low-temperature ESR assurance, defined ripple-current capability, and long-term endurance (4000 hours at 125 °C), alongside AEC-Q200 qualification and RoHS compliance for regulated markets.

Key Features

• Electrical Performance — 300 µF capacitance with 100 V rated voltage and ±20% tolerance; polarized electrolytic construction suited for power decoupling and energy storage in high-voltage SMD designs.
• Low-Temperature ESR Specification — ESR characterized at low temperature with an added ESR specification after the -40 °C test and impedance stability data provided for -40 °C to +20 °C conditions.
• Ripple Current Capability — Rated ripple currents of 850 mA at 120 Hz and 1.7 A at 10 kHz, supporting dynamic power filtering requirements where high-frequency ripple is present.
• High-Temperature Endurance — Rated for continuous operation up to +125 °C with an established lifetime of 4000 hours at 125 °C.
• AEC-Q200 Qualified & RoHS Compliant — Meets AEC-Q200 qualification and is compliant with the RoHS directive (2011/65/EU,(EU)2015/863), addressing reliability and regulatory requirements.
• Surface-Mount, Tape-Feed Compatible Package — Chip-type radial can SMD format designed for automatic mounting machines fed with carrier tape; compact package dimensions L: 2.15 cm × D: 1.8 cm with recommended land size 1.83 cm × 1.83 cm.
• Soldering Heat Resistance — Specified resistance to soldering heat (250 °C for 30 seconds on a hot plate) with post-heat performance requirements for capacitance, tan δ and leakage current.

Typical Applications

• Automotive electronics — Designed to meet AEC-Q200 qualification and the high-temperature requirements of automotive modules and control electronics.
• Power filtering in high-temperature environments — 300 µF / 100 V rating with defined ripple-current performance and 125 °C endurance makes it suitable for power rail decoupling where elevated ambient or internal temperatures occur.
• Automated surface-mount assemblies — Chip-type radial can SMD package compatible with carrier-tape feeding for high-volume automated placement processes.

Unique Advantages

• High-temperature reliability: Endurance specified at 4000 hours at 125 °C provides a documented profile for long-term use in elevated-temperature systems.
• Low-temperature performance assurance: Includes ESR specification after -40 °C testing and impedance ratio data to support designs that must operate across wide temperature ranges.
• Balanced high-voltage/high-capacitance: 300 µF at 100 V gives substantial energy storage in a compact SMD can package for high-voltage applications.
• Established ripple handling: Defined ripple-current ratings at both low (120 Hz) and high (10 kHz) frequencies to support mixed-frequency power environments.
• Production-ready packaging: Carrier-tape compatibility and SMD can format simplify integration into automated assembly lines.
• Regulatory and quality alignment: AEC-Q200 qualification and RoHS compliance help meet industry reliability expectations and regulatory constraints.
