URS2E470MHD

The URS2E470MHD is a compact, low-profile aluminum electrolytic capacitor in a radial-lead can, specified at 47 µF and 250 V. Designed for general-purpose electronic assemblies, it provides polarized capacitance in a small φ18 × 20 mm package with 7.5 mm lead spacing for through-hole mounting.

Key electrical characteristics include a tangent of loss angle (tanδ) of 0.16 (measured at 20°C, 120 Hz), specified ripple current ratings for low and high frequency operation, and an endurance rating of 2000 hours at 85°C. Availability note: this part is listed as End Of Life.

Key Features

• Capacitance & Tolerance — 47 µF nominal with tolerance of −20% to +20% to match many general-purpose circuit requirements.
• Rated Voltage — 250 V working voltage for higher-voltage DC applications requiring through-hole electrolytic capacitance.
• Low-profile radial-can package — φ18 × 20 mm can with radial leads and 7.5 mm lead spacing (±0.5 mm) for straightforward PCB through-hole mounting and mechanical stability.
• Loss characteristic — tanδ = 0.16 (measured at 20°C, 120 Hz), enabling predictable AC loss behavior in design calculations.
• Ripple current capability — Low-frequency ripple current: 420 mA at 120 Hz; high-frequency ripple current: 672 mA at 10 kHz, supporting AC ripple handling across frequency ranges.
• Leakage current — Specified leakage current of 570 µA for initial charge/current budgeting.
• Endurance & temperature range — Rated for 2000 hours at 85°C and an operating temperature range of −40°C to +85°C to meet elevated-temperature endurance needs.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to suit production handling preferences.

Typical Applications

• General-purpose power filtering — Provides 47 µF, 250 V polarized capacitance for bulk smoothing and filtering in power circuits where a compact, through-hole capacitor is desirable.
• Supply decoupling in higher-voltage designs — Suited for decoupling or local energy storage on 250 V rails within industrial or electronic equipment requiring radial-lead components.
• Retrofit and repair — Low-profile radial form factor and standard lead spacing make this capacitor practical for service, replacement, and legacy board designs.

Unique Advantages

• Compact, low-profile can — φ18 × 20 mm dimensions deliver needed capacitance while minimizing board height and occupying a small PCB footprint.
• High working voltage — 250 V rating supports higher-voltage DC applications without stepping up component count.
• Frequency-aware ripple ratings — Specified ripple current values at both 120 Hz and 10 kHz help designers assess thermal and ripple performance across typical operating frequencies.
• Predictable loss and leakage — Measured tanδ and specified leakage current allow accurate modeling of dissipation and standby current in designs.
• Through-hole ease-of-use — Radial lead spacing at 7.5 mm (±0.5 mm) simplifies PCB layout and manual or wave-solder assembly processes.
• Endurance under elevated temperature — 2000-hour rating at 85°C gives a clear baseline for expected life in thermally demanding environments.
