UHD1A102MPD

The UHD1A102MPD is a high-reliability, miniature aluminum electrolytic capacitor from Nichicon’s UHD series. It is a polarized, radial-lead device specified at 1000 µF and 10 V, designed for compact power filtering and decoupling applications.

Engineered for sustained operation across a wide temperature range (−40°C to 105°C) and rated for 3000 hours at 105°C, this part delivers high ripple-current capability and low impedance at higher frequencies in a small φ8×20 mm can.

Key Features

• Capacitance & Voltage — 1000 µF nominal capacitance with a rated voltage of 10 V and a tolerance of −20% to +20%.
• Low Loss — Tangent of loss angle (tan δ) of 0.19 measured at 20°C, 120 Hz, supporting efficient energy handling with reduced dissipation.
• High Ripple Current — Low-frequency ripple current of 937.5 mA at 120 Hz and high-frequency ripple current of 1.25 A at 100 kHz for robust AC stress handling.
• Compact Radial Package — φ8×20 mm can with radial lead mounting and 3.5 mm lead spacing (±0.5 mm) enables space-efficient through-hole placement.
• Endurance & Temperature — Rated for 3000 hours at 105°C and specified operating temperature range from −40°C to 105°C for reliable long-term use in elevated-temperature environments.
• Leakage Current — Specified leakage current of 100 µA (after 2 minutes at 20°C), facilitating predictable standby and bias behavior.
• RoHS Compliance — Conforms to RoHS requirements, supporting environmentally regulated designs.
• Packaging Options — Available in bulk (no terminal forming) and bag packing to suit production and prototyping workflows.

Typical Applications

• Power Supply Filtering — 1000 µF at 10 V with high ripple-current capability is well suited for smoothing and bulk energy storage on low-voltage power rails.
• Decoupling for Power Modules — Compact φ8×20 mm size and low impedance at higher frequencies support decoupling in dense DC‑DC converter and regulator layouts.
• Embedded and Industrial Electronics — Wide −40°C to 105°C operating range and 3000 h endurance at 105°C provide reliable performance in demanding embedded and industrial environments.

Unique Advantages

• High AC Stress Tolerance: Measured ripple currents (937.5 mA at 120 Hz, 1.25 A at 100 kHz) allow the capacitor to handle significant AC loading without compromising performance.
• Small Footprint: φ8×20 mm radial can minimizes board area while delivering 1000 µF capacitance for compact designs.
• Predictable Loss Characteristics: tan δ = 0.19 at 20°C/120 Hz supports designers in assessing dissipation and thermal management.
• Long-Term Reliability: Rated endurance of 3000 hours at 105°C documents sustained performance under elevated-temperature stress.
• Through-Hole Ease of Use: Radial lead form and standard 3.5 mm lead spacing simplify prototyping and assembly for through-hole assemblies.
• Regulatory Compliance: RoHS-compliant construction supports environmentally conscious product requirements.
