UHE1H271MHD6

The UHE1H271MHD6 is a miniature, radial-lead aluminum electrolytic capacitor in Nichicon’s UHE series, offering 270 µF capacitance at a 50 V rating. Designed for general-purpose power filtering and decoupling, it combines low impedance and compact size with extended endurance for reliable operation in space-constrained electronic designs.

This part is optimized for applications that require stable capacitance over a wide temperature range (–40 °C to +105 °C), rated ripple handling at both low and high frequencies, and long life up to 10,000 hours at 105 °C.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a rated voltage of 50 V and capacitance tolerance of ±20% (–20% ~ +20%).
• Low Impedance — Specified impedance of 200 mΩ, supporting low-loss filtering and improved transient response.
• High Ripple Handling — Rated ripple currents of 882 mA at 120 Hz (low frequency) and 1.26 A at 10 kHz (high frequency) for effective smoothing across frequency ranges.
• Long Endurance — Life rating up to 10,000 hours at 105 °C when used within specified conditions, supporting extended service life in thermal-stressed environments.
• Wide Temperature Range — Operates from –40 °C to +105 °C to cover demanding ambient conditions.
• Compact Radial Can — Small can size φ12.5 × 15 mm length with radial lead mounting and 5 mm lead spacing (±0.5 mm), enabling compact PCB layouts.
• Leakage & Loss — Typical leakage current specified at 135 µA and tangent of loss angle (tan δ) of 0.1 at 20 °C, 120 Hz for predictable dissipation characteristics.
• Packaging & Production — Available in bulk or bag packing (no terminal forming) and currently in mass production. Marking is printed in white on a black sleeve per series standard.

Typical Applications

• Power supply filtering — Bulk smoothing and output filtering in DC power supplies where 270 µF/50 V and specified ripple currents meet design requirements.
• Decoupling for converters — Local energy storage and decoupling for switching regulators and DC–DC converters benefiting from low impedance and high ripple capability.
• Industrial and consumer electronics — General-purpose use in equipment that requires compact electrolytic capacitance with long-term endurance and wide temperature operation.

Unique Advantages

• Space-efficient form factor: The φ12.5 × 15 mm can and radial lead configuration make it easy to fit into dense PCB designs without sacrificing capacitance.
• Enhanced ripple endurance: Specified ripple currents at 120 Hz and 10 kHz support reliable smoothing across both low- and high-frequency noise components.
• Low ESR/Impedance: 200 mΩ impedance helps minimize voltage drop and heat generation during transient events, improving circuit stability.
• Extended operational life: Rated for up to 10,000 hours at 105 °C, providing predictable aging and maintenance planning for long-life products.
• Wide operating temperature: –40 °C to +105 °C rating enables deployment in applications exposed to harsh ambient conditions.
• RoHS compliant: Meets RoHS directive requirements for environmental compliance.
