UHW1J271MPD

The UHW1J271MPD is a Nichicon UHW series miniature aluminum electrolytic capacitor in a radial‑lead can, offering 270 µF capacitance at a 63 V rating. It targets general‑purpose power designs that require compact size, sustained ripple handling and elevated temperature endurance.

Designed for applications where lower impedance at higher frequencies and extended life are important, this part combines a φ10×20 mm can with a 5 mm lead spacing and a rated operating range of −40 °C to +105 °C.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 63 V and a capacitance tolerance of −20% to +20%.
• High ripple current capability — Low‑frequency ripple current 785 mA (120 Hz) and high‑frequency ripple current 1.57 A (10 kHz) for improved performance under AC stress.
• Low impedance — Rated impedance of 340 mΩ and series characteristics noting lower impedance at high frequency ranges to support decoupling and filtering tasks.
• Low loss — Tangent of loss angle (tan δ) of 0.09 measured at 20 °C, 120 Hz, contributing to stable performance.
• Leakage current — Measured leakage current of 170.1 µA after rated voltage application conditions.
• Temperature & endurance — Operating temperature range −40 °C to +105 °C with a rated life/endurance of 12,000 hours at 105 °C.
• Compact radial package — φ10 × 20 mm can, radial lead mounting with 5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing.
• Compliance & availability — RoHS compliant and available in mass production.

Typical Applications

• General‑purpose power filtering — Provides bulk capacitance and ripple handling for general‑purpose power supplies and regulators where compact radial cans are required.
• High‑ripple power circuits — Suited for circuit locations exposed to significant AC ripple thanks to specified low‑ and high‑frequency ripple current ratings.
• Compact electronic modules — φ10×20 mm can and 5 mm lead spacing enable use in space‑constrained power assemblies and PCB layouts.
• Long‑life thermal environments — The 12,000‑hour endurance at 105 °C supports designs that require extended operational stability at elevated temperatures.

Unique Advantages

• Measured high ripple capability: Specified ripple currents (785 mA @120 Hz, 1.57 A @10 kHz) allow designers to place this capacitor where AC stress is expected without overspecifying.
• Low impedance at frequency: 340 mΩ impedance and documented lower impedance in the high‑frequency range help improve power integrity and transient response.
• Compact radial form factor: φ10×20 mm can with 5 mm lead spacing provides a balance of capacitance and PCB space savings for radial‑lead assemblies.
• Extended high‑temperature life: Rated for 12,000 hours at 105 °C, supporting longer service intervals in hot operating environments.
• Controlled loss and leakage: tan δ of 0.09 and leakage current of 170.1 µA contribute to predictable behavior in bias and filtering applications.
• RoHS compliant and production ready: Meets RoHS requirements and is in mass production for straightforward procurement and supply continuity.
