UVK1A103MHD

The UVK1A103MHD is a Nichicon UVK-series aluminum electrolytic capacitor in a radial-lead, can package. It delivers 10,000 µF capacitance at a rated voltage of 10 V in a compact φ16 × 30.5 mm body with 7.5 mm lead spacing.

Designed for general-purpose electronic circuits, the UVK1A103MHD combines high capacitance, substantial ripple handling, and a broad operating temperature range (−40 °C to 85 °C) for use in a wide range of low-voltage applications.

Key Features

• High Capacitance — 10,000 µF nominal capacitance (±20%) provides significant charge storage for low-voltage systems.
• Low-Voltage Rating — Rated for 10 V operation to suit 5 V and other low-voltage rails in embedded and power electronics.
• Radial Lead Package — Through-hole radial leads with 7.5 mm spacing and bulk/bag packing options simplify prototyping and manual assembly.
• Solid Ripple Performance — Low-frequency ripple current of 2.55 A (120 Hz) and high-frequency ripple current of 2.933 A (10 kHz) for demanding AC conditions.
• Electrical Loss Characterization — Measured tangent of loss angle (tan δ) of 0.42 at 20 °C, 120 Hz (10 V), enabling designers to account for ESR-related losses.
• Reliability and Endurance — Rated for 2,000 hours at 85 °C; specified endurance performance after life test returns within ±20% capacitance change and leakage limits.
• Wide Operating Temperature — −40 °C to 85 °C operating range suitable for many industrial and consumer environments.
• RoHS Compliant — Manufactured to meet RoHS requirements.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and smoothing on low-voltage rails where high charge storage is required in a compact radial package.
• Through-hole prototyping and assembly — Radial lead format and bag/bulk packing support hand-assembly and repair workflows.
• Low-voltage energy buffering — 10,000 µF capacitance supplies temporary charge for circuits operating at or below the 10 V rating.

Unique Advantages

• High capacitance in a compact footprint — 10,000 µF in a φ16 × 30.5 mm can allows significant energy storage without large board area.
• Designed for AC stress — Specified ripple current values at 120 Hz and 10 kHz support designs with both low- and high-frequency ripple components.
• Clear loss specification — Measured tan δ (0.42 at 20 °C, 120 Hz) helps engineers model dissipative behavior and thermal rise.
• Robust operating range and endurance — −40 °C to 85 °C rating and 2,000 hours endurance at 85 °C enable predictable long-term behavior in many environments.
• Simple procurement and handling — Bulk (no terminal forming) and bag packing options ease inventory and assembly logistics.
