UHW1C332MHD

The UHW1C332MHD from Nichicon is a radial-lead aluminum electrolytic capacitor in the UHW series, engineered for general-purpose electronic designs that require high ripple handling and compact size. It delivers 3300 µF capacitance at a 16 V rating with low impedance and lifecycle endurance suitable for sustained operation.

Designed for applications where high-frequency performance and long-term reliability matter, this part combines low impedance (45 mΩ), high ripple current capability, and a wide operating temperature range to support power filtering and decoupling in a small radial can package.

Key Features

• Capacitance & Voltage: 3300 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20% for predictable bulk energy storage.
• High Ripple Current: Rated for 2.4 A at 120 Hz (low frequency) and 3.2 A at 10 kHz (high frequency), supporting demanding ripple environments.
• Low Impedance: Typical impedance of 45 mΩ aids in reducing voltage ripple and improving transient response at power rails.
• Long Endurance & Temperature Range: Life rating of 10,000 hours at 105°C and an operating temperature range of −40°C to +105°C for extended reliability under elevated temperatures.
• Compact Radial Can: Small footprint with dimensions φ12.5×25L and lead spacing of 5.0 mm (±0.5 mm) for through-hole PCB layouts.
• RoHS Compliant & Packaging Options: RoHS-compliant construction with bulk (no terminal forming) and bag packing options for flexible procurement and assembly handling.

Typical Applications

• General-purpose power filtering: Smoothing and decoupling on 16 V power rails where 3300 µF capacitance and low impedance are required.
• Power-supply ripple management: Handling AC ripple and switching noise with rated ripple currents of 2.4 A (120 Hz) and 3.2 A (10 kHz).
• Embedded and industrial electronics: Compact radial-can format and wide −40°C to +105°C operating range support integration into space-constrained assemblies operating across temperature extremes.

Unique Advantages

• High ripple tolerance: 2.4 A (120 Hz) and 3.2 A (10 kHz) ratings allow the capacitor to manage significant AC stress on power lines without derating performance.
• Low ESR/Impedance: 45 mΩ impedance reduces power loss and improves voltage stability in filtering and decoupling applications.
• Durable at elevated temperature: 10,000-hour life at 105°C provides predictable long-term performance in hot operating environments.
• Compact, through-hole package: φ12.5×25L radial can with 5 mm lead spacing simplifies PCB layout where space and mechanical stability are considerations.
• Wide ambient tolerance: −40°C to +105°C operating range supports use across a broad set of environmental conditions.
• RoHS compliance and packing flexibility: Environmentally compliant construction with bulk or bag packing options to suit production handling.
