URZ2E470MHD

The URZ2E470MHD is a miniature, standard-type aluminum electrolytic capacitor from Nichicon’s URZ series. It is a radial-lead, polarized capacitor specified at 47 µF and 250 V, designed for general-purpose power and decoupling tasks where a compact, through-hole electrolytic solution is required.

Its compact φ18 × 20 mm can and radial package provide a low-profile option for equipment requiring moderate capacitance, high voltage handling, and rated endurance across a wide operating temperature range.

Key Features

• Capacitance & Tolerance — 47 µF nominal capacitance with tolerance of −20% to +20%, suitable for bulk decoupling and smoothing applications.
• High Voltage Rating — Rated for 250 V, allowing use in higher-voltage power rails and circuits that require elevated working voltage.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.16 measured at 20°C and 120 Hz, providing defined dissipation characteristics for AC and ripple conditions.
• Ripple Current Capability — Low-frequency ripple current 300 mA at 120 Hz and high-frequency ripple current 480 mA at higher frequencies, supporting AC ripple handling in power applications.
• Leakage Current — Specified leakage current of 570 µA, useful for predicting static losses in hold-up and filter circuits.
• Temperature & Endurance — Operating temperature range −40°C to +105°C with a rated life of 1000 hours at 105°C, enabling sustained operation in elevated-temperature environments.
• Compact Radial Package — Can diameter φ18 mm, length 20 mm, and 7.5 mm lead spacing (±0.5 mm) in a radial lead can for through-hole mounting and straightforward PCB placement.
• Packaging Options — Available in bulk (no terminal forming) or bag packing to suit manual assembly or automation-prep workflows.

Typical Applications

• Power Supply Filtering — Bulk smoothing and decoupling on mid- to high-voltage power rails where 250 V rating and 47 µF capacitance are required.
• Industrial Control Electronics — Energy storage and ripple suppression in control boards and drives operating within −40°C to +105°C ambient ranges.
• Consumer and Commercial Equipment — General-purpose decoupling and hold-up in appliances and instrumentation that use radial through-hole components.
• Signal Conditioning and Power Modules — Local energy buffering and ripple attenuation in power modules and conditioning stages needing defined leakage and tan δ characteristics.

Unique Advantages

• High working voltage capability: 250 V rating lets designers use a single component for higher-voltage rails, reducing the need for multiple capacitors in series.
• Defined ripple performance: Specified low- and high-frequency ripple currents (300 mA at 120 Hz, 480 mA at higher frequencies) help ensure predictable thermal and lifetime behavior under AC stress.
• Compact, low-profile radial can: φ18 × 20 mm dimensions with 7.5 mm lead spacing deliver a space-efficient through-hole option for PCB layouts that require elevated voltage handling.
• Wide operating temperature and rated endurance: −40°C to +105°C operating range and 1000 hours at 105°C life rating support reliable operation in thermally demanding applications.
• Clear electrical characterization: Specified tan δ and leakage current values (0.16 and 570 µA respectively) allow designers to model dissipation and standby losses accurately.
• Flexible packing choices: Bulk or bag packing accommodates manual assembly and preparation for automated processes.
