UHE1J271MHD6

The UHE1J271MHD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHE series. It is a radial-lead, polarized capacitor rated at 270 µF and 63 V, designed for general-purpose electronic applications that require low impedance and extended operational life.

Key design attributes include a compact φ12.5 × 20 mm can, a wide operating temperature range of −40 °C to +105 °C and a specified endurance of 10,000 hours at 105 °C, making it suitable for designs where long-term stability and thermal endurance are required.

Key Features

• Electrical Capacity: 270 µF nominal capacitance with tolerance −20% to +20% to support bulk energy storage and smoothing where this capacitance value is required.
• Voltage Rating: 63 V rated DC working voltage for mid-voltage power applications.
• Low Impedance: Impedance specified at 640 mΩ, supporting lower ripple voltage under load relative to higher-impedance parts.
• Loss Factor (tan δ): tanδ = 0.09 measured at 20 °C, 120 Hz, indicating controlled dissipation for the rated voltage and frequency.
• Ripple Current Capability: 535.5 mA at 120 Hz (low frequency) and 765 mA at 10 kHz (high frequency), enabling use with both lower- and higher-frequency ripple environments.
• Leakage Current: Specified leakage current of 170.1 µA, measured after voltage application conditions described by the manufacturer.
• Long Life / Endurance: Rated for 10,000 hours at 105 °C under DC bias plus rated ripple current, aligned with UHE series long-life performance.
• Package & Mounting: Radial lead can (φ12.5 × 20 mm) with 5 mm lead spacing (±0.5 mm). Available in bulk (no terminal forming) or bag packing.
• Environmental Compliance: RoHS compliant.

Typical Applications

• General-purpose power circuits: For designs requiring 270 µF at up to 63 V where long life and low impedance are needed.
• Industrial electronics: Where extended endurance at elevated temperature (10,000 h at 105 °C) and reliable ripple handling are necessary.
• Compact assemblies with radial mounting: The φ12.5 × 20 mm radial-can package and 5 mm lead spacing fit space-constrained through-hole layouts.

Unique Advantages

• Proven long-life performance: 10,000-hour endurance at 105 °C supports extended field life in high-temperature environments.
• Controlled dissipation: Low tanδ (0.09 at 20 °C, 120 Hz) helps limit self-heating and energy loss in continuous operation.
• Broad ripple frequency coverage: Specified ripple current at both 120 Hz and 10 kHz offers predictable behavior across low- and high-frequency ripple conditions.
• Compact radial form factor: φ12.5 × 20 mm can with standard 5 mm lead spacing simplifies retrofits and through-hole board designs.
• Low impedance for improved filtering: 640 mΩ impedance aids in reducing voltage ripple and stabilizing supply rails.
• Regulatory compliance: RoHS compliant to align with environmental requirements.
