URS1H331MHD

The URS1H331MHD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s URS series. It delivers 330 µF of capacitance at a 50 V rating in a compact, low-profile φ12.5 × 12.5 mm can designed for general-purpose electronics.

Engineered for space-conscious through-hole designs, this polarized capacitor offers measurable performance characteristics—low loss (tan δ = 0.12 at 20°C, 120 Hz), defined leakage current, and specified ripple current ratings—making it suitable for a wide range of general-purpose applications.

Key Features

• Capacitance & Voltage: 330 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of ±20% (measured at 120 Hz, 20°C).
• Compact, Low-Profile Package: φ12.5 × 12.5 mm can size provides a compact footprint for space-limited boards while maintaining radial through-hole mounting.
• Radial Lead Mounting: Standard radial-lead can package with 5.0 mm lead spacing (±0.5 mm tolerance) for reliable through-hole assembly.
• Ripple Current Capability: Rated low-frequency ripple current of 530 mA at 120 Hz and high-frequency ripple current of 795 mA at 10 kHz—specified for predictable performance under AC ripple loading.
• Loss and Leakage Characteristics: Tangent of loss angle (tan δ) = 0.12 (20°C, 120 Hz) and leakage current specified at 495 µA for controlled dissipation and standby behavior.
• Endurance & Temperature Range: Specified life of 2000 hours at 85°C and operating temperature range of −40°C to +85°C for defined long-term performance under elevated temperature conditions.
• Packaging Options: Available in bulk (no terminal forming) or bag packing to suit assembly and handling preferences.

Typical Applications

• General Purpose Electronics: Suited for circuits requiring a 330 µF, 50 V polarized capacitor in a compact radial-lead form for general-purpose use.
• Power Supply Filtering: Provides defined ripple-current handling (530 mA at 120 Hz; 795 mA at 10 kHz) for smoothing and filtering on DC rails.
• Space-Constrained Designs: Low-profile φ12.5 × 12.5 mm package and radial leads make it suitable for compact boards and constrained assemblies operating from −40°C to +85°C.

Unique Advantages

• Compact footprint: φ12.5 × 12.5 mm can delivers 330 µF capacitance in a small, low-profile package for space-limited layouts.
• Predictable ripple performance: Specified ripple current values at both low and high frequencies let designers size capacitors for known AC conditions.
• Controlled dissipation: tan δ = 0.12 (20°C, 120 Hz) gives a quantified loss characteristic for thermal and ESR considerations.
• Defined leakage: Leakage current of 495 µA provides a verifiable standby characteristic for power budgeting and design validation.
• Durability at elevated temperature: 2000 hours endurance at 85°C enables designers to account for long-term performance in warmer environments.
• Through-hole usability: Standard radial-lead package with 5.0 mm lead spacing (±0.5 mm) simplifies prototyping and conventional PCB assembly.
