UHD1V330MDD

The UHD1V330MDD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHD series, engineered for compact through-hole applications that require reliable capacitance and elevated ripple handling. This 33 µF, 35 V polarized capacitor combines a small φ5 × 11 mm can with the UHD series’ low-impedance, high-ripple characteristics to serve general-purpose power decoupling and filtering needs in electronic assemblies.

Key Features

• Capacitance & Voltage – Rated at 33 µF and 35 V to support a variety of general-purpose power and decoupling functions.
• Low Impedance / High Ripple Capability – Designed within the UHD series’ low-impedance profile; specified ripple currents of 137.5 mA at 120 Hz and 250 mA at 100 kHz enable improved AC stress handling for compact power rails.
• Loss and Leakage Characteristics – Tangent of loss angle (tanδ) of 0.12 (measured at 20°C, 120 Hz) and leakage current specified at 11.55 µA support predictable dissipation and standby behavior.
• Compact Radial Package – Small footprint can (φ5 × 11 mm) with radial leads and 2.0 mm lead spacing (±0.5 mm) for convenient through-hole mounting in tight layouts.
• Operating Range and Endurance – Rated for −40°C to +105°C with a life endurance of 2000 hours, suitable for a broad set of environmental conditions.
• RoHS Compliant & Packaging Options – RoHS-compliant construction; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-purpose electronics – Provides capacitance for power smoothing and decoupling in compact through-hole assemblies where 33 µF / 35 V is required.
• Compact power modules – Small can size and defined ripple ratings make it suitable for local energy storage and ripple suppression in tight power supply layouts.
• Consumer and industrial devices – Useful in assemblies that require a stable polarized capacitor across a wide temperature range (−40°C to +105°C).

Unique Advantages

• High ripple performance for a small can: Specified ripple currents of 137.5 mA (120 Hz) and 250 mA (100 kHz) enable reliable AC stress handling without increasing footprint.
• Predictable loss and leakage: tanδ of 0.12 at 35 V and leakage current of 11.55 µA provide measurable electrical behavior for margin and thermal planning.
• Compact radial form factor: φ5 × 11 mm can and 2 mm lead spacing allow easy integration into space-constrained through-hole PCB designs.
• Wide operating temperature: −40°C to +105°C rating supports a broad range of environmental conditions.
• RoHS compliance and simple packaging: Lead-free construction and bulk or bag packing options simplify procurement and assembly workflows.
