UUG1H102MNQ1MS

The UUG1H102MNQ1MS is a surface‑mount aluminum electrolytic capacitor from Nichicon’s UUG series, delivering 1000 µF capacitance at a 50 V rating. Designed as a chip‑type, higher‑capacitance SMD can, it targets applications that require compact bulk capacitance with defined endurance and ripple handling.

Key attributes include AEC‑Q200 qualification for automotive use, an operating temperature range of −40 °C to +85 °C, and an endurance specification of 2000 hours at 85 °C—making it suitable for demanding power‑filtering and energy‑smoothing roles in regulated environments.

Key Features

• Capacitance & Tolerance: 1000 µF nominal capacitance with ±20% tolerance measured at 120 Hz, 20 °C for predictable bulk energy storage.
• Rated Voltage: 50 V rating for mid‑voltage power rails and DC link decoupling.
• Low and High Frequency Ripple Handling: Rated ripple current of 1.15 A at 120 Hz and 1.323 A at 10 kHz, supporting both low‑frequency smoothing and higher‑frequency switching environments.
• Loss Tangent (tan δ): tan δ = 0.12 specified at 20 °C, 120 Hz and 50 V, enabling engineers to assess ESR‑related dissipation for thermal and ripple calculations.
• Leakage Current: Specified leakage current of 1500 µA after one minute at rated voltage and 20 °C, useful for standby and hold‑up time budgeting.
• Endurance & Temperature Range: Life rating of 2000 hours at 85 °C with operating range −40 °C to +85 °C, supporting long‑term stability under elevated temperature stress.
• Package & Mounting: Chip‑type SMD can in case size φ18 × 21.5 mm, surface‑mount (radial can — SMD), with a recommended land size of 1.83 × 1.83 cm for PCB layout.
• AEC‑Q200 Rated: Qualified under AEC‑Q200, targeting applications requiring automotive‑grade component reliability.

Typical Applications

• Automotive Power Rails: Bulk decoupling and smoothing on 12 V/24 V vehicle electronics where AEC‑Q200 qualification and defined endurance are required.
• DC‑DC Converters and Regulators: Output filtering and energy buffering for converters that need high capacitance in a compact surface‑mount can.
• Infotainment and Body Electronics: Bulk energy storage to stabilize supply rails for audio, display, and control modules operating across −40 °C to +85 °C.

Unique Advantages

• High Capacitance in SMD Form: 1000 µF nominal in a φ18 × 21.5 mm chip‑type can simplifies PCB layout where board space and through‑hole routing are constrained.
• Automotive‑Grade Qualification: AEC‑Q200 rating gives confidence for use in vehicle systems and other environments demanding elevated reliability standards.
• Broad Ripple Capability: Separate ripple ratings for low (120 Hz) and high (10 kHz) frequencies allow designers to size capacitors for both power‑line smoothing and switching regulator demands.
• Defined Endurance: 2000 hours at 85 °C offers predictable lifetime behavior for thermal budgeting and maintenance planning.
• Wide Operating Temperatures: −40 °C to +85 °C supports operation across typical automotive and industrial ambient conditions.
