UHW0J472MHD

The UHW0J472MHD is a radial-lead aluminum electrolytic capacitor providing 4700 µF capacitance at a 6.3 V rating in a compact φ12.5 × 25 mm can. It is designed for general-purpose power applications that require high ripple current handling, low impedance and extended endurance in elevated-temperature environments.

Key value propositions include high ripple capability (2.72 A at 120 Hz, 3.2 A at 10 kHz), a low impedance of 45 mΩ, and a rated lifetime of 10,000 hours at 105°C—delivering reliable energy smoothing in space-constrained through-hole designs.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with a rated voltage of 6.3 V and tolerance of −20% to +20% for bulk energy storage and decoupling.
• High Ripple Current — Rated ripple current of 2.72 A at 120 Hz (low frequency) and 3.2 A at 10 kHz (high frequency) to support demanding power-supply filtering and converter output stages.
• Low Impedance — Typical impedance of 45 mΩ helps minimize voltage drop and heat generation under load.
• Electrical Losses — Tangent of loss angle (tanδ) specified at 0.27 measured at 20°C, 120 Hz for predictable AC loss behavior.
• Leakage Current — Measured leakage current of 296.1 µA, suitable for power applications where standby leakage is a consideration.
• High Temperature Endurance — Rated life of 10,000 hours at 105°C for long-term stability in elevated ambient conditions.
• Package & Mounting — Polarized radial-lead can in φ12.5 × 25 mm size with 5 mm lead spacing (±0.5 mm tolerance) for through-hole assembly and secure mechanical retention.
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing to support production handling preferences.

Typical Applications

• Power supply bulk filtering — Provides bulk capacitance and energy smoothing for linear and switching power supplies where high ripple current and low impedance are required.
• DC‑DC converter output stages — Supports output decoupling in compact through-hole designs with 3.2 A ripple capability at high frequencies (10 kHz).
• Industrial control power rails — Offers long endurance (10,000 hours at 105°C) and robust thermal performance for continuous-operation control electronics.
• Consumer electronics power management — Compact φ12.5 × 25 mm can and radial leads simplify board placement while delivering the capacitance and ripple handling needed for power-rail stability.

Unique Advantages

• Compact, high-capacitance form factor — 4700 µF in a φ12.5 × 25 mm can enables high energy density for space-constrained through-hole designs.
• High ripple handling across frequencies — Specified ripple currents at both 120 Hz and 10 kHz support reliable performance in low- and high-frequency power applications.
• Low ESR/impedance — 45 mΩ impedance reduces losses and thermal stress under load, improving system efficiency and stability.
• Extended high-temperature life — 10,000-hour rating at 105°C provides predictable long-term behavior in elevated temperature environments.
• Production-friendly packaging — Bulk and bag packing options accommodate different manufacturing workflows without unnecessary terminal forming.
• Regulatory compliance — RoHS compliant for contemporary environmental requirements.
