UHW1A472MHD

The UHW1A472MHD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering a compact, miniature footprint with high ripple-current capability and engineered reliability. It provides 4700 µF capacitance at 10 V in a φ12.5 × 30.5 mm can with 5 mm lead spacing, optimized for general-purpose circuit applications that require bulk capacitance and high-frequency performance.

Designed for long life under elevated temperature, this part is rated for operation from −40°C to 105°C and a 10 000‑hour endurance at 105°C. It is RoHS compliant and available in bulk or bag packing for production use.

Key Features

• Capacitance & Voltage — 4700 µF nominal capacitance at a 10 V rated voltage, with tolerance of −20% to +20% for bulk energy storage and decoupling.
• High Ripple Current — Low-frequency ripple current of 3.226 A (120 Hz) and high-frequency ripple current of 3.795 A (10 kHz) to support demanding AC/bias conditions.
• Low Impedance — Rated impedance of 36 mΩ, delivering reduced voltage drop and improved filtering performance at high frequencies.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.24 measured at 20°C, 120 Hz (10 V measurement condition), supporting predictable dissipation behavior.
• Reliability & Lifetime — Endurance specified at 10 000 hours at 105°C; leakage current specified at 470 µA, suitable for long-term thermal stress.
• Compact Radial Package — φ12.5 × 30.5 mm can (L: 3.05 × D: 1.25 cm) with 5 mm lead spacing (±0.5 mm) for through‑hole mounting and simple PCB integration.
• Environmental Compliance — RoHS compliant.

Typical Applications

• General-purpose electronics — Bulk smoothing and decoupling where a 4700 µF, 10 V polarized capacitor is required and compact radial mounting is preferred.
• Power rails and regulation — Filtering and energy buffering on low-voltage DC rails that demand high ripple-current handling and low impedance.
• High-frequency filtering — Use where lower impedance at higher frequencies improves transient response and ripple attenuation.

Unique Advantages

• High ripple capacity in a small footprint: 3.226 A (120 Hz) and 3.795 A (10 kHz) ripple ratings combined with a φ12.5 × 30.5 mm can minimize board space while handling substantial AC stress.
• Predictable thermal endurance: 10 000‑hour life at 105°C supports designs that must maintain capacitance and dissipation characteristics under elevated temperatures.
• Low series impedance: 36 mΩ impedance helps reduce voltage ripple and improves regulator and converter stability.
• Measured dissipation factor: tan δ = 0.24 at 20°C/120 Hz (10 V) gives a documented baseline for power-loss and thermal planning.
• Easy through-hole implementation: Standard radial-lead form factor with 5 mm lead spacing and bulk/bag packing options for assembly flexibility.
• Regulatory compliance: RoHS status simplifies inclusion in designs targeting regulated markets.
