URZ2G470MRD6

The URZ2G470MRD6 is a radial-lead aluminum electrolytic capacitor delivering 47 µF of capacitance at a 400 V rating. It is designed for general-purpose power applications that require compact high-voltage capacitance in a through-hole form factor.

Key value propositions include a compact φ20 × 20 mm can, a wide operating temperature range of -40°C to 105°C, and specified ripple-current performance at both low and high frequencies for use in DC bus smoothing and power-supply filtering scenarios.

Key Features

• Nominal Capacitance & Tolerance  47 µF with ±20% tolerance, suitable for bulk decoupling and energy-storage duties where specified capacitance range is acceptable.
• High Voltage Rating  Rated to 400 V, enabling use on higher-voltage DC buses and power stages requiring elevated working voltages.
• Ripple Current Performance  Low-frequency ripple current of 300 mA (120 Hz) and high-frequency ripple current of 480 mA (10 kHz), supporting filtering across a range of switching and line frequencies.
• Leakage Current  Specified leakage current of 852 µA, provided as a measured characteristic for bias and standby-current budgeting.
• Thermal and Endurance  Operating range -40°C to 105°C with an endurance rating of 1000 hours at 105°C, defined for life/aging planning and thermal stress assessments.
• Package and Mounting  Radial lead, can-style package with φ20 × 20 mm dimensions and 10 mm lead spacing (±0.5 mm) for conventional through-hole mounting and straightforward PCB layout.
• Packaging Options  Available in bulk (no terminal forming) or bag packing to support different assembly and handling preferences.

Typical Applications

• High‑Voltage Power Supplies  Bulk smoothing and energy storage on high-voltage DC rails where 400 V rating and 47 µF capacitance meet design requirements.
• DC Link / Inverter Stages  Support for DC link decoupling in power conversion circuits that require through-hole components for serviceability or prototyping.
• Switching Regulator Filtering  Ripple attenuation across low and high switching frequencies, leveraging specified ripple-current characteristics at 120 Hz and 10 kHz.

Unique Advantages

• High-voltage capability: 400 V rating allows use on elevated DC buses without series stacking.
• Compact radial can: φ20 × 20 mm size offers a small footprint for through-hole designs where board space is constrained.
• Broad temperature range: Rated from -40°C to 105°C, supporting applications exposed to varied thermal conditions.
• Defined ripple performance: Separate low- and high-frequency ripple-current specifications (300 mA @120 Hz, 480 mA @10 kHz) make selection and thermal budgeting more precise.
• Clear endurance data: 1000 hours at 105°C gives a measured basis for lifetime and reliability planning.
