UCZ1E122MNS1MS

The UCZ1E122MNS1MS is a chip‑type, surface‑mount aluminum electrolytic capacitor in Nichicon’s UCZ series designed for high‑reliability, high‑temperature operation. It delivers 1.2 mF capacitance at 25 V in a compact φ16 × 16.5 mm SMD can with embossed carrier taping for automated placement.

Engineered for demanding environments, this part combines AEC‑Q200 qualification, an extended −40 °C to +125 °C operating range, and long endurance (3500 hours at 125 °C), making it suitable for challenging power applications where temperature, ripple current and low ESR are critical.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a rated voltage of 25 V and tolerance of −20% to +20%.
• High‑Temperature Endurance — Rated endurance of 3500 hours at 125 °C, supporting long‑life operation in elevated ambient conditions.
• Low‑Loss Performance — Tan δ of 0.18 (measured at 20 °C, 120 Hz) for controlled dielectric loss at rated conditions.
• Low ESR & High Ripple Capability — ESR of 47 mΩ (20 °C, 100 kHz) with low‑frequency ripple current of 850 mA (120 Hz) and high‑frequency ripple current of 1.7 A (10 kHz), enabling effective smoothing and decoupling in power stages.
• Leakage Current — Specified leakage current of 300 µA, supporting predictable bias behavior after voltage application.
• Surface‑Mount Packaging — Chip/Can SMD package (φ16 × 16.5 mm) with embossed carrier taping for automated assembly and compact board placement; surface mount land size provided.
• Reliability & Compliance — AEC‑Q200 qualification and RoHS compliance for use in regulated and reliability‑sensitive designs.

Typical Applications

• Automotive Power Electronics — Filter and energy‑storage capacitor for power rails in automotive control modules, benefiting from AEC‑Q200 qualification and 125 °C endurance.
• DC‑DC Converters — Bulk smoothing and output decoupling in converters where low ESR and high ripple current handling reduce voltage ripple and improve efficiency.
• Power Supply Smoothing — Bulk energy reservoir for board‑level power supplies in industrial and embedded systems operating across a wide temperature range.
• Industrial Control Systems — Robust decoupling and filtering for motor drives, inverters, and other systems exposed to vibration and elevated temperatures.

Unique Advantages

• High‑temperature reliability: 3500 hours endurance at 125 °C provides predictable lifetime performance in hot operating environments.
• High ripple capacity with low ESR: 1.7 A (10 kHz) ripple rating and 47 mΩ ESR enable efficient handling of fast current transients and power switching noise.
• AEC‑Q200 qualification: Design reassurance for reliability‑sensitive applications including automotive and transportation electronics.
• Compact SMD can format: φ16 × 16.5 mm package and embossed carrier taping support automated assembly and dense power board layouts.
• Stable loss characteristics: tan δ specified (0.18 at 20 °C, 120 Hz) for predictable AC performance during design verification.
