UHE1C472MHD6

The UHE1C472MHD6 is a miniature, radial-lead aluminum electrolytic capacitor engineered for general-purpose electronic use. It delivers high capacitance in a compact can-style package and is optimized for low impedance and extended endurance.

With a 16 V rating, 4700 µF capacitance, and a wide operating temperature range of −40 °C to 105 °C, this capacitor addresses power smoothing, bulk energy storage, and ripple-handling requirements in compact consumer and industrial designs.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance with a tolerance of −20% to +20% at a rated voltage of 16 V, suitable for bulk energy storage on mid-voltage rails.
• Low Impedance — Rated impedance of 49 mΩ and a tangent of loss angle (tan δ) of 0.22 measured at 20 °C, 120 Hz, supporting low-loss operation and improved transient response.
• High Ripple Current Capability — Low-frequency ripple current of 2.512 A at 120 Hz and high-frequency ripple current of 3.14 A at 10 kHz for effective AC ripple handling across common power frequencies.
• Long Endurance — Specified life of 10,000 hours at 105 °C, providing extended reliability under elevated temperature and bias conditions.
• Wide Temperature Range — Rated for operation from −40 °C to 105 °C to support applications across varied environmental conditions.
• Compact Radial Package — Aluminum can package with dimensions φ18 × 25 mm (length) and 7.5 mm lead spacing (±0.5 mm), available in bulk or bag packing for through-hole assembly.
• Low Leakage — Specified leakage current of 752 µA, contributing to predictable bias performance in DC applications.
• RoHS Compliant — Conforms to RoHS requirements for materials compliance.

Typical Applications

• General-purpose power filtering — Smoothing low-frequency ripple on 16 V power rails using 2.512 A ripple capability at 120 Hz.
• Decoupling and bulk storage — Local energy reservoir for converters and regulators where 4700 µF capacitance and low impedance (49 mΩ) aid voltage stability during transient loads.
• Industrial and consumer electronics — Durable operation over −40 °C to 105 °C and 10,000-hour endurance make it suitable for longer-life equipment and assemblies.

Unique Advantages

• High ripple tolerance: Supports significant AC ripple at both low and high frequencies (2.512 A at 120 Hz, 3.14 A at 10 kHz), reducing thermal stress in demanding power circuits.
• Low-loss performance: 49 mΩ impedance and a measured tan δ of 0.22 help minimize power dissipation and improve efficiency in power-handling applications.
• Extended lifetime at elevated temperature: 10,000 hours rated life at 105 °C enhances system reliability where long-term thermal endurance is required.
• Space-efficient radial can: φ18 × 25 mm footprint with 7.5 mm lead spacing provides a high-capacitance option for compact through-hole designs.
• Predictable leakage behavior: Specified leakage current of 752 µA provides a known baseline for bias and standby current budgeting.
• Regulatory readiness: RoHS compliance supports material-restricted designs and environmental requirements.
