UHW1A102MPD

The UHW1A102MPD is a miniature, radial‑lead aluminum electrolytic capacitor designed for high‑reliability, general‑purpose applications. It delivers 1000 µF of capacitance in a compact φ10×12.5L can with a 5 mm lead spacing and is supplied in bulk or bag packing for production use.

Engineered for demanding power applications, the part combines low impedance, high ripple handling and long endurance across a wide temperature range (‑40°C to +105°C), making it suitable for compact power filtering and energy‑buffering roles in embedded and industrial designs.

Key Features

• Capacitance and Voltage — 1000 µF rated capacitance at 10 V with a tolerance of ‑20% to +20%, providing substantial bulk capacitance in a small package.
• High Ripple Current — Low‑frequency ripple current of 1.02 A (120 Hz) and high‑frequency ripple current of 1.7 A (10 kHz), enabling effective handling of both mains‑frequency and switching noise.
• Low Impedance — Rated impedance of 150 mΩ and optimized for lower impedance in the high‑frequency range, improving voltage stability on DC‑DC converter outputs and transient response.
• Reliability and Endurance — Endurance specified at 10,000 hours at 105°C, supporting long life in elevated‑temperature environments when operated within ratings.
• Electrical Losses and Leakage — Tangent of loss angle (tan δ) of 0.18 measured at 20°C, 120 Hz and specified leakage current of 100 µA, allowing predictable dissipation and standby characteristics.
• Environmental Compliance and Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for automated or manual assembly processes.

Typical Applications

• Power Supply Filtering — Compact bulk capacitance and low impedance make it suitable for smoothing and output filtering in low‑voltage power supplies and regulators.
• DC‑DC Converter Output — High ripple current capability and low impedance at switching frequencies help stabilize converter outputs and reduce voltage ripple.
• Embedded and Industrial Electronics — Small footprint, wide operating temperature range (‑40°C to +105°C) and long endurance support use in space‑constrained embedded modules and industrial control equipment.

Unique Advantages

• Compact, high‑capacitance package — 1000 µF in a φ10×12.5L can minimizes PCB area while delivering substantial energy storage for bulk decoupling.
• High ripple handling across frequencies — Specified ripple current at both 120 Hz and 10 kHz supports mixed mains and switching environments without derating performance.
• Predictable electrical performance — Specified impedance (150 mΩ), tan δ (0.18 at 20°C/120 Hz) and leakage current (100 µA) enable accurate power‑budget and thermal calculations.
• Long operational life — 10,000 hours endurance at 105°C reduces maintenance and replacement needs in continuous‑operation systems.
• Radial‑lead convenience — Through‑hole radial lead form with 5 mm lead spacing simplifies prototyping and legacy PCB designs.
• RoHS compliant — Meets environmental directive requirements for lead‑free assemblies.
