UCZ2A301MNS1MS

The UCZ2A301MNS1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UCZ series, offering 300 µF nominal capacitance at a 100 V rating. Built as a chip-type, high-reliability component, it targets power filtering and energy-storage roles in demanding environments where elevated temperature, vibration resistance, and automated assembly are required.

Key value comes from its high-voltage capability, extended endurance at elevated temperature, and assembly-ready SMD can packaging—making it suitable for applications that require stable capacitance, controlled loss (tan δ), and robust ripple handling across low and high frequencies.

Key Features

• Capacitance & Voltage — 300 µF nominal capacitance with a rated voltage of 100 V and capacitance tolerance of ±20% (120 Hz, 20°C).
• High-temperature endurance — Endurance rating of 4000 hours at 125°C, supporting continuous operation in elevated-temperature environments.
• Controlled dissipation (tan δ) — tan δ = 0.10 measured at 20°C, 120 Hz, 100 V, providing predictable loss characteristics for AC and ripple conditions.
• Low ESR — ESR of 110 mΩ measured at 20°C and 100 kHz, supporting efficient high-frequency performance.
• Ripple current capability — Low-frequency ripple current 850 mA (120 Hz) and high-frequency ripple current 1.7 A (10 kHz), enabling effective smoothing across a range of switching frequencies.
• Leakage current — Specified leakage current of 300 μA, suitable for power designs with defined leakage budgets.
• Wide operating temperature — Rated for −40°C to +125°C operation, with low-temperature ESR specification after −40°C testing.
• Surface-mount package & assembly — Radial can SMD (chip type) in φ18 × 21.5L size, supplied in embossed carrier taping for automatic pick-and-place assembly; vibration resistant.
• Compliance & qualification — RoHS compliant and AEC-Q200 qualified, indicating suitability for reliability-focused and automotive-grade designs.

Typical Applications

• Automotive power electronics — Bulk filtering and decoupling in modules where AEC-Q200 qualification and operation to 125°C are required.
• DC–DC converters and power supplies — Energy storage and ripple attenuation for converters operating across low and high switching frequencies.
• Industrial control systems — High-temperature-capable smoothing and decoupling in compact, board-level power stages exposed to vibration.
• Telecommunications & server power — Bulk capacitance for intermediate DC buses and transient energy buffering where stable ESR and ripple handling are important.

Unique Advantages

• High-voltage capacitance in an SMD can — Delivers 300 µF at 100 V in a φ18 can footprint, enabling compact high-voltage designs.
• Extended high-temperature life — 4000 hours at 125°C supports long-term reliability in thermally challenging applications.
• Broad ripple-frequency support — Separate low- and high-frequency ripple ratings (850 mA @120 Hz, 1.7 A @10 kHz) provide design flexibility across switching regimes.
• Predictable loss and low ESR — tan δ = 0.10 (120 Hz) and 110 mΩ ESR at 100 kHz give measurable performance targets for filter and decoupling design.
• Assembly-ready packaging — Supplied in embossed carrier tape and compatible with automatic placement, reducing assembly handling and time.
• Qualification and compliance — AEC-Q200 qualification and RoHS compliance support use in regulated and reliability-sensitive product lines.
