UCZ2A181MNS1MS

The UCZ2A181MNS1MS is a surface-mount, chip-type aluminum electrolytic capacitor engineered for high-reliability power applications. It delivers 180 µF at a 100 V rating with a wide operating temperature range of -40 °C to 125 °C and endurance specified to 3,500 hours at 125 °C.

Designed for automated assembly and vibration-resistant operation, this AEC‑Q200 qualified, RoHS-compliant device is targeted at power filtering, smoothing and energy-buffering tasks where elevated temperature tolerance, stable ESR and high ripple capability are required.

Key Features

• Electrical Characteristics — 180 µF nominal capacitance with tolerance ±20% and rated voltage 100 V for high-voltage power rails and DC link applications.
• Low Loss / ESR — ESR of 170 mΩ measured at 20 °C and 100 kHz, supporting efficient high-frequency decoupling and reduced power dissipation.
• Ripple Current Capability — Low-frequency ripple handling of 550 mA at 120 Hz and high-frequency ripple handling of 1.1 A at 10 kHz for robust filtering under dynamic load.
• High-Temperature Endurance — Endurance rated to 3,500 hours at 125 °C, enabling reliable operation in thermally demanding environments.
• Wide Operating Range & Loss Tangent — Operating range -40 °C to 125 °C with tan δ (DF) ≤ 0.10 at 20 °C, 120 Hz and 100 V for predictable performance across temperature.
• Surface-Mount, Automated Assembly — Chip-type can SMD package (φ18 × 16.5 mm) provided in embossed carrier taping for pick-and-place mounting and reflow processing.
• Qualification & Compliance — AEC‑Q200 rating and RoHS compliance for regulated and automotive-grade designs; vibration-resistant construction for mechanically demanding applications.

Typical Applications

• Automotive Power Conditioning — Suitable for voltage smoothing and decoupling on vehicle power rails and ECUs where AEC‑Q200 qualification and high temperature tolerance matter.
• DC–DC Converters and Power Supplies — Energy buffering and output filtering for converters requiring 100 V rating and high ripple capability.
• Industrial Drive Electronics — Filtering and bulk capacitance in motor drives and inverters exposed to elevated temperatures and mechanical vibration.
• Telecom and Infrastructure Power Modules — Bulk decoupling and smoothing in high-voltage subsystems that demand stable ESR and long endurance at temperature.

Unique Advantages

• High Voltage Handling: 100 V rating supports higher-voltage rails without increasing capacitor count.
• Temperature-Rated Reliability: Endurance of 3,500 hours at 125 °C ensures durable performance in hot environments.
• Balanced Frequency Performance: Low ESR at 100 kHz plus specified ripple currents at 120 Hz and 10 kHz provide effective performance across low- and high-frequency noise.
