UPW1C272MHD6

The UPW1C272MHD6 is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UPW series, optimized for low impedance and high reliability in compact power designs. It delivers 2700 µF at a 16 V rating with a small 16 mm diameter × 20 mm length package and is intended for use in switching power supplies and automotive electronic modules that require long-term stability under elevated temperatures.

Key Features

• Capacitance & Voltage: 2.7 mF (2700 µF) rated at 16 V with ±20% tolerance for bulk decoupling and energy storage.
• Low Impedance: 58 mΩ impedance to support transient suppression and low-voltage-drop filtering in power rails.
• Ripple Current Handling: High ripple capability—1.879 A at 120 Hz (low frequency) and 2.21 A at 10 kHz (high frequency)—for demanding switching environments.
• Loss Characteristics: tan δ (DF) = 0.18 measured at 20°C, 120 Hz, providing a quantifiable dissipation factor for thermal and loss budgeting.
• Leakage Current: 1296 µA specified leakage current for initial screening and power-loss calculations.
• High-Temperature Endurance: Rated for 8000 hours at 105°C, supporting long lifetime operation in hot enclosures.
• Temperature Range & Reliability: Operates from −55°C to +105°C and is AEC-Q200 rated for applications requiring defined reliability standards.
• Compact Radial Package: φ16 × 20L can with radial leads, 7.5 mm lead spacing (±0.5 mm), and available in Bulk (No Terminal Forming) or Bag packing.
• Polarized Construction: Polar capacitor suitable for DC power circuits requiring correct polarity installation.

Typical Applications

• Switching Power Supplies: Output smoothing and bulk decoupling where low impedance and high ripple capability improve transient response.
• Automotive Electronics: Energy storage and filtering in automotive electronic modules where AEC-Q200-rated components and 105°C endurance are required.
• Compact Power Conversion: Space-constrained DC/DC converters and power modules benefiting from the UPW1C272MHD6’s small φ16×20 mm footprint and radial-lead mounting.

Unique Advantages

• High ripple capacity: 1.879 A at 120 Hz and 2.21 A at 10 kHz enables reliable handling of switching currents without excessive heating.
• Low impedance for transient control: 58 mΩ impedance helps minimize voltage ripple and improves regulator stability.
• Designed for high-temperature endurance: 8000 hours at 105°C supports long-term deployment in elevated-temperature environments.
• Automotive-grade reliability: AEC-Q200 rating provides a defined reliability baseline for automotive and similarly demanding applications.
• Space-efficient form factor: φ16 × 20L can with 7.5 mm lead spacing fits tightly packed PCBs while still providing substantial capacitance.
• Packaging flexibility: Available in Bulk (No Terminal Forming) or Bag packing to match production and assembly workflows.
