UVZ1A330MDD

The UVZ1A330MDD is a miniature aluminum electrolytic capacitor in Nichicon’s UVZ series, configured as a radial-lead, polarized device with a 33 µF capacitance at 10 V. It is designed for general-purpose electronic applications that require compact energy storage, decoupling and smoothing in low-voltage circuits.

Key attributes include a compact 5 mm × 11 mm can, wide operating temperature range from −55 °C to 105 °C, and defined ripple and leakage characteristics—making it suitable for space-constrained designs that demand stable performance across temperature extremes.

Key Features

• Capacitance & Voltage — 33 µF nominal capacitance with ±20% tolerance, rated for 10 V operation per part specifications.
• Electrical Loss — Tangent of loss angle (tan δ) of 0.24 measured at 20 °C and 120 Hz, providing a defined dissipation factor for design margin calculations.
• Ripple Handling — Low-frequency ripple current of 58 mA at 120 Hz and high-frequency ripple current of 116 mA at 10 kHz, supporting both bulk and higher-frequency decoupling needs.
• Leakage Current — Specified leakage current of 9.9 µA for predictable off-state behavior in standby and low-power conditions.
• Thermal & Endurance — Rated operating range −55 °C to 105 °C with endurance specified as 1000 hours at 105 °C, consistent with UVZ series endurance parameters.
• Compact Radial Package — φ5 × 11 mm can with 2.0 mm lead spacing (±0.5 mm tolerance) and radial-lead mounting suitable for through-hole assembly; supplied in bulk bag packing (no terminal forming).
• RoHS Compliant — Conforms to RoHS requirements as noted in product and series documentation.

Typical Applications

• Portable and Handheld Electronics — Small can size (φ5 × 11 mm) and low-voltage rating make the capacitor suitable for power-rail smoothing and local energy storage in compact devices.
• Power-Supply Decoupling — Defined ripple current specs at 120 Hz and 10 kHz support decoupling on low-voltage regulator outputs and intermediate power rails.
• Control and Interface Circuits — Low leakage and stable performance across −55 °C to 105 °C help maintain signal stability in control electronics and sensor interfaces.

Unique Advantages

• Compact footprint: φ5 × 11 mm can allows designers to save board space while retaining useful capacitance for low-voltage circuits.
• Wide temperature capability: −55 °C to 105 °C operating range supports designs exposed to broad environmental conditions.
• Defined ripple performance: Separate low- and high-frequency ripple ratings (58 mA at 120 Hz, 116 mA at 10 kHz) enable predictable thermal and electrical design trade-offs.
• Predictable leakage and loss: Specified leakage current (9.9 µA) and tan δ (0.24 at 120 Hz, 20 °C) simplify power budgeting and ESR/DF modeling.
• Through-hole radial form factor: Robust radial-lead mounting and standard lead spacing facilitate mechanical retention and easy prototyping or repair.
• RoHS compliance: Meets RoHS directive requirements as indicated in the product information.
