UCZ1E122MNQ1MS

The UCZ1E122MNQ1MS is a surface-mount aluminum electrolytic capacitor from Nichicon's UCZ series, designed for chip-type, high-reliability applications. It delivers 1.2 mF capacitance at 25 V with a broad operating temperature range and endurance suitable for elevated-temperature environments.

Targeted use cases include automotive and industrial electronics where AEC-Q200 qualification, high ripple handling and low ESR at 100 kHz are required. The part is compatible with automated assembly through embossed carrier taping and supports operation from −40°C to +125°C.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) rated at 25 V with ±20% tolerance for bulk energy storage and decoupling.
• Low ESR — 47 mΩ ESR measured at 20°C / 100 kHz, enabling improved high-frequency performance.
• High Ripple Current Capability — 850 mA at 120 Hz (low frequency) and 1.7 A at 10 kHz (high frequency) to handle AC stress and transient currents.
• Wide Temperature Range — Specified for operation from −40°C to +125°C, with endurance tested at elevated temperature.
• Endurance — 3500 hours at 125°C (endurance condition for the φ16 case size), providing sustained performance under high-temperature operation.
• Package & Assembly — Chip-type radial can in SMD package (φ16 × 16.5L) supplied in embossed carrier taping for automatic placement.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant for regulated environments.
• Leakage & Loss — Leakage current specified at 300 µA and tan δ (DF) of 0.18 at 20°C, 120 Hz for predictable loss characteristics.

Typical Applications

• Automotive Electronics — AEC-Q200 qualification and −40°C to +125°C rating make this capacitor suitable for automotive control modules and power subsystems that require high-reliability SMD electrolytics.
• Automated Surface-Mount Production — Supplied in embossed carrier taping and compatible with automatic mounting machines, streamlining high-volume board assembly.
• High-Temperature Electronics — Endurance of 3500 hours at 125°C supports use in systems and environments operating at elevated temperatures.

Unique Advantages

• High ripple tolerance: Rated ripple currents of 850 mA (120 Hz) and 1.7 A (10 kHz) reduce thermal stress during AC and transient loading.
• Low high-frequency ESR: 47 mΩ at 100 kHz helps maintain stable impedance at switching frequencies and minimizes heating under HF ripple.
• Broad temperature endurance: Operation from −40°C to +125°C and 3500 h endurance at 125°C support long-term reliability in demanding thermal environments.
• Production-ready packaging: Embossed carrier taping simplifies pick-and-place integration for automated assembly lines.
• Standards compliance: AEC-Q200 rating and RoHS compliance align the component with regulated and quality-focused programs.
