UPW1C121MED

The UPW1C121MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPW series configured as a radial lead can. With a rated capacitance of 120 µF at 16 V, it is engineered for applications that require compact power decoupling and reliable ripple handling across a wide temperature range.

This part targets power electronics and embedded systems where stable capacitance, controlled loss tangent, and endurance at elevated temperatures are important—particularly in designs that benefit from AEC‑Q200 qualification and robust through-hole mounting.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable bulk energy storage and decoupling.
• Low-loss Performance — Specified tanδ of 0.16 (measured at 20°C, 120 Hz) to provide controlled dissipation for stable performance in filtering and smoothing applications.
• Ripple Current Capability — Rated low-frequency ripple current of 188.5 mA at 120 Hz and high-frequency ripple current of 290 mA at 10 kHz, enabling effective handling of switching and high-frequency noise components.
• Leakage Current — Specified leakage current of 57.6 µA for reduced standby loss and predictable bias behavior after application of rated voltage.
• High Temperature Endurance — Endurance rating of 2000 hours at 105°C to support long-term operation in thermally demanding environments.
• Automotive-Grade Reliability — AEC‑Q200 rating for passive component stress testing, supporting use in automotive and other demanding electronics systems.
• Compact Radial Package — Small can size φ6.3 × 11 mm with radial lead mounting and 2.5 mm lead spacing (±0.5 mm), suitable for through-hole designs requiring a small footprint.
• Operating Range — Wide operating temperature range from −55°C to +105°C for reliable operation across harsh environmental conditions.

Typical Applications

• Switching Power Supplies — Bulk smoothing and output filtering where miniature size and high ripple handling improve power rail stability.
• Automotive Electronics — Power decoupling and transient suppression in automotive control modules and sensors, supported by AEC‑Q200 qualification and 105°C endurance.
• Industrial Control — Decoupling and energy storage in motor drives, controllers, and embedded power subsystems that require robust temperature and ripple performance.
• Embedded Systems — Local power filtering on PCB power rails where through-hole mounting and compact dimensions aid mechanical robustness and serviceability.

Unique Advantages

• Compact energy density: 120 µF in a φ6.3 × 11 mm can minimizes board space while providing useful bulk capacitance for decoupling.
• Designed for ripple handling: Specified ripple current at both low and high frequencies supports performance in switching and high-frequency applications.
• High-temperature durability: 2000 hours at 105°C gives designers quantified endurance for thermal stress scenarios.
• Predictable electrical behavior: Defined tanδ and leakage current figures enable reliable circuit modeling and power-budgeting.
• Automotive-capable qualification: AEC‑Q200 rating provides an added level of stress-tested reliability for automotive and similarly demanding markets.
• Through-hole robustness: Radial lead construction with defined lead spacing simplifies mechanical mounting and serviceability in rugged applications.
