UCZ1V102MNQ1MS

The UCZ1V102MNQ1MS is a chip-type aluminum electrolytic capacitor from the Nichicon UCZ series designed for high-temperature, high-reliability applications. It delivers 1 mF capacitance at a 35 V rating in a surface-mount radial can package optimized for automated tape-fed assembly.

Engineered for operation from −40 °C to +125 °C and AEC‑Q200 qualified, this component targets automotive and other demanding systems that require stable capacitance, defined ESR behavior at low temperature, and long-term endurance under elevated temperatures.

Key Features

• Core Type – Chip aluminum electrolytic: Chip-type construction for compact bulk capacitance in a surface-mount can package suitable for automated mounting.
• Temperature range: Rated for −40 °C to +125 °C operation, enabling use in high-temperature environments.
• Capacitance & voltage: 1 mF (1000 µF) nominal capacitance with a 35 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• Low-temperature ESR specification: ESR characterized after −40 °C testing; nominal ESR 47 mΩ measured at 100 kHz.
• Ripple current ratings: Specified ripple current of 1.2 A at 120 Hz and 2.4 A at 10 kHz, supporting power filtering and decoupling duties.
• Reliability & endurance: AEC‑Q200 qualified with a rated lifetime of 3500 hours at 125 °C in the specified package; leakage current and tan δ meet series endurance criteria after the specified treatment.
• Package & mounting: Surface-mount radial can (SMD) compatible with carrier-tape feeding for automatic placement; recommended land size L: 1.63 × W: 1.63 cm.
• Environmental compliance: RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive power modules: Bulk energy storage and smoothing for ECU power rails and drive electronics where AEC‑Q200 qualification and high-temperature endurance are required.
• DC–DC converters and power supplies: Input/output filtering and decoupling for converters operating up to +125 °C, leveraging the 1 mF capacitance and specified ripple current capability.
• Motor drives and inverters: Energy buffering and noise suppression in power electronics that encounter elevated temperatures and require defined ESR performance.
• Sensor and instrumentation power systems: Stable decoupling and hold-up capacitance for sensors and measurement electronics operating in harsh thermal conditions.

Unique Advantages

• High-temperature endurance: Rated lifetime of 3500 hours at +125 °C supports prolonged operation in elevated-temperature assemblies.
• Defined low-temperature behavior: ESR specified after −40 °C testing and a measured 47 mΩ ESR at 100 kHz provide predictable performance across the operating range.
• AEC‑Q200 qualified: Qualification to AEC‑Q200 indicates suitability for applications that demand automotive-grade reliability.
• Assembly-friendly package: Surface-mount radial can in tape-fed format simplifies automated placement and high-volume production flow.
• Measurable ripple handling: Published ripple current values at both low and high frequencies (1.2 A at 120 Hz, 2.4 A at 10 kHz) help designers size capacitors for real-world power conditions.
• Regulatory compliance: RoHS compliance supports use in regulated markets and simplifies product approvals.
