UHW1V470MDD

The UHW1V470MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering a compact φ5×11 mm can and polarized radial-lead package for general-purpose power decoupling and filtering. It combines high ripple-current capability with a small footprint, making it suitable for space-constrained designs that require stable capacitance across a wide temperature range.

Key electrical attributes include 47 µF capacitance at ±20% tolerance, a 35 V rated voltage, low-frequency ripple handling of 180 mA (120 Hz) and high-frequency ripple handling of 450 mA (10 kHz). Note: product status is End Of Life.

Key Features

• Capacitance & Voltage — 47 µF nominal capacitance with tolerance −20% to +20% and rated for 35 V operation.
• High ripple current capability — Designed for 180 mA ripple current at 120 Hz and 450 mA at 10 kHz, supporting AC ripple and decoupling in power circuits.
• Low dissipation factor — tan δ of 0.11 (measured at 20°C, 120 Hz, 35 V) for reduced AC loss and improved thermal behavior under ripple loading.
• Compact radial-lead package — φ5 × 11 mm can with 2 mm lead spacing and radial leads for through-hole mounting in tight layouts.
• Wide operating temperature — Specified for −40°C to +105°C, suitable for many industrial and commercial electronic environments.
• Long-term endurance — Rated life of 7000 hours at 105°C under specified conditions.
• Low leakage — Measured leakage current of 16.45 µA, supporting low-standby and precision circuits.
• RoHS compliant — Meets RoHS directive requirements for restricted substances.
• Packaging — Supplied in bulk (no terminal forming) or bag packing to support production and prototyping workflows.

Typical Applications

• Power supply decoupling — Provides bulk and ripple filtering on low-voltage DC rails where a compact, polarized capacitor is required.
• DC/DC converter output smoothing — Handles high-frequency ripple current and helps stabilize output voltage in compact regulator modules.
• Embedded and consumer electronics — Suited for space-constrained boards needing reliable capacitance across −40°C to +105°C operating ranges.

Unique Advantages

• Compact size with high ripple capability: φ5×11 mm can delivers meaningful ripple handling (180 mA @120 Hz, 450 mA @10 kHz) for designs where PCB real estate is limited.
• Quantified thermal endurance: 7000 hours at 105°C provides a measurable reliability target for thermal-stressed designs.
• Low dissipation and leakage: tan δ of 0.11 and 16.45 µA leakage help minimize heat generation and standby losses in power-sensitive applications.
• Through-hole radial-lead form factor: Simplifies prototyping and repair, and is compatible with standard through-hole assembly processes.
• RoHS compliance: Supports regulatory requirements for restricted substances in commercial and industrial products.

Why Choose UHW1V470MDD?

The UHW1V470MDD pairs a small radial-lead package with rated 35 V operation and robust ripple-current performance, making it a practical choice for engineers designing compact power circuits and decoupling networks. Its specified endurance at elevated temperature and defined electrical parameters (tan δ, leakage current, frequency-dependent ripple capability) allow predictable integration into thermal and reliability analyses.

This capacitor is well suited to procurement for high-density board layouts, through-hole prototypes, and production runs where space and ripple performance are primary considerations. RoHS compliance and clear endurance data support longer-term product planning and regulatory needs.
