UHD1V271MPD

The UHD1V271MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHD series, offering 270 µF capacitance at 35 V with a compact φ8×20 mm can. It is designed for general-purpose use where low impedance at higher frequencies and robust ripple handling are required.

With a wide operating temperature range of −40°C to 105°C and a rated endurance of 3000 hours at 105°C, this capacitor suits designs that demand sustained ripple performance and stable behavior across temperature extremes.

Key Features

• Capacitance & Voltage: 270 µF rated capacitance at 35 V with tolerance −20% to +20% for predictable energy storage in DC circuits.
• Low Loss / High-frequency Performance: Tangent of loss angle (tanδ) of 0.12 (measured at 20°C, 120 Hz) and series design characteristics that deliver lower impedance at high frequency ranges.
• High Ripple Current Capability: Supports 875 mA at 120 Hz (low frequency) and 1.25 A at 100 kHz (high frequency), enabling effective smoothing and decoupling under AC ripple conditions.
• Leakage Current: Low leakage current specified at 94.5 µA (measured at 20°C after rated voltage application), useful for power-sensitive applications.
• Robust Endurance & Temperature Range: Rated for 3000 hours at 105°C; operating temperature −40°C to +105°C for reliable performance in elevated-temperature environments.
• Compact Radial Package: φ8×20 mm can with 3.5 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies; available in bulk (no terminal forming) or bag packing.
• Compliance & Production Status: RoHS compliant and listed as mass production.

Typical Applications

• General-purpose power filtering: Use where low impedance at higher frequencies and reliable ripple handling are required for smoothing DC rails.
• Decoupling and bulk energy storage: Provides local energy reservoir and decoupling in circuits that need compact through-hole capacitors with measured leakage and tolerance characteristics.
• High-ripple environments: Suitable for circuits that impose significant ripple currents thanks to rated ripple performance at both low and high frequency.

Unique Advantages

• Measurable high-frequency behavior: Lower impedance characteristics and a specified tanδ value at 120 Hz help engineers predict AC loss and thermal behavior.
• Documented ripple capability: Explicit ripple current ratings at 120 Hz and 100 kHz allow confident selection for both low- and high-frequency ripple conditions.
• Wide temperature and proven endurance: −40°C to 105°C range with 3000 h endurance at 105°C supports long-term operation in elevated-temperature designs.
• Through-hole radial format: Compact φ8 can and 3.5 mm lead spacing simplify replacement, prototyping, and integration into existing through-hole assemblies.
• Regulatory compliance: RoHS compliance provides assurance for environmental and regulatory requirements.
