UVK0J472MHD

The UVK0J472MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon's UVK series. It provides 4700 µF capacitance at a 6.3 V rating in a compact φ12.5 × 20 mm can designed for general-purpose power filtering and decoupling in through-hole assemblies.

Engineered for demanding ripple environments and extended operation, the part delivers specified low-frequency and high-frequency ripple current capability, defined ESR and leakage figures, and a 2000 hour endurance at 85°C—offering a balance of size, reliability and measurable performance for designers of power rails and embedded equipment.

Key Features

• Capacitance & Voltage — 4700 µF (4.7 mF) nominal capacitance with ±20% tolerance at a 6.3 V rated voltage, suitable for bulk energy storage and decoupling on low-voltage rails.
• Ripple Current & ESR — Low-frequency ripple current 1.55 A (120 Hz) and high-frequency ripple current 1.7825 A (10 kHz) with an ESR of 340 mΩ at 120 Hz, providing predictable AC performance for filtering and smoothing.
• Leakage & Dissipation — Specified leakage current of 888.3 µA and a tangent of loss angle (tan δ) of 0.34 measured at 20°C, 120 Hz, enabling engineering trade-offs between leakage and capacitance for standby and runtime conditions.
• Reliability & Lifetime — Rated endurance of 2000 hours at 85°C with stable capacitance and controlled tan δ and leakage after the life test, supporting long-term operation in elevated-temperature environments.
• Mechanical & Packaging — Radial lead, polarized can in a compact φ12.5 × 20L size with 5.0 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Operating Temperature & Compliance — Operating range from −40°C to +85°C and RoHS-compliant construction for regulatory alignment in general-purpose electronic designs.

Typical Applications

• Power supply smoothing — Bulk capacitance and 1.55 A ripple current rating make the UVK0J472MHD suitable for smoothing and reservoir roles on low-voltage DC rails.
• Decoupling for embedded systems — Large capacitance in a miniature can supports decoupling and transient energy demands in board-level power distribution for consumer and industrial electronics.
• Audio and signal filtering — Low-frequency ripple performance and defined ESR help stabilize supplies feeding analog and audio front-ends where steady DC is required.

Unique Advantages

• Compact, high-capacity package: 4700 µF in a φ12.5 × 20 mm can reduces board area compared to larger form factors, enabling denser through-hole designs.
• Defined ripple capability: Separate low- and high-frequency ripple current ratings (1.55 A at 120 Hz, 1.7825 A at 10 kHz) allow designers to quantify AC stress across a range of operating frequencies.
• Measurable ESR and loss characteristics: ESR specified at 340 mΩ (120 Hz) and tan δ measured at 0.34 give clear parameters for thermal and impedance budgeting in power designs.
• Designed for elevated-temperature endurance: 2000 hours at 85°C rating supports reliable operation in environments with sustained thermal stress.
• Flexible assembly options: Radial-lead through-hole package with 5.0 mm lead spacing and bulk or bag packing accommodates manual assembly and wave/hand-solder workflows.
• RoHS compliant and production-ready: RoHS status and mass-production availability streamline procurement and compliance for volume designs.
