UHW1C472MHD

The UHW1C472MHD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can designed for general-purpose electronic applications. It delivers 4700 µF of capacitance at a 16 V rating with low impedance and high allowable ripple current for demanding power filtering tasks.

Engineered for extended operation across a wide temperature range (−40 °C to 105 °C) and a rated endurance of 10,000 hours at 105 °C, this radial-lead UHW-series part targets designs that require dependable smoothing and energy storage in a compact package (φ12.5 × 35.5 mm).

Key Features

• Capacitance & Voltage — 4700 µF capacitance at a 16 V rated voltage with a tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current: 3.502 A (120 Hz); high-frequency ripple current: 4.12 A (10 kHz), supporting heavy AC overlay and switching applications.
• Low Impedance — Rated impedance of 33 mΩ and series characteristics optimized for lower impedance at high frequency.
• Loss Factor — tanδ (DF) 0.21 measured at 20 °C, 120 Hz for the 16 V rating.
• Leakage Current — Specified leakage current of 752 µA.
• High Endurance — Designed for 10,000 hours of life at 105 °C under rated voltage and ripple conditions.
• Mechanical & Mounting — Radial lead package, can size φ12.5 × 35.5 mm, lead spacing 5 mm (±0.5 mm) suitable for through-hole assembly.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple smoothing where a 4700 µF, 16 V capacitor is required for stable DC rails.
• Switching power supplies and regulators — Handles high ripple current requirements at both low and high frequencies to support switching converters and post-regulation stages.
• Embedded and industrial electronics — Suited for designs requiring long endurance (10,000 h at 105 °C) and operation across −40 °C to 105 °C.

Unique Advantages

• High ripple current capability — Supports 3.502 A at 120 Hz and 4.12 A at 10 kHz, enabling robust smoothing under AC overlay and switching conditions.
• Compact, miniature footprint — φ12.5 × 35.5 mm can size delivers 4700 µF in a small radial-lead package to save board space.
• Low impedance at high frequency — 33 mΩ impedance and series design reduce voltage ripple and improve transient response.
• Long operational life — 10,000-hour endurance at 105 °C for sustained reliability in elevated-temperature environments.
• Through-hole radial lead form — Simplifies assembly for applications that prefer or require axial/through-hole mounting styles.
• Regulatory compliance — RoHS compliant for global electronics manufacturing requirements.
