UHE1H271MPD

The UHE1H271MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHE series, offering 270 µF capacitance at a 50 V rating. It is designed for general-purpose electronic designs that require compact energy storage, decoupling and smoothing with a long rated life and low impedance.

Packaged in a φ10 × 20 mm can with 5 mm lead spacing, this component provides defined ripple-current performance at both low and high frequencies and is RoHS compliant.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 50 V rated voltage and capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 240 mΩ, supporting improved ripple damping and stable performance under load.
• Ripple Current Specified — Low-frequency ripple current of 854 mA at 120 Hz and high-frequency ripple current of 1.22 A at 10 kHz, with frequency coefficients available for other frequencies.
• Long Endurance — Rated for 7,000 hours at 105 °C under DC bias plus rated ripple current (series-level endurance specification for 16–100 V units).
• Temperature & Loss Characteristics — Operating range −40 °C to 105 °C and tangent of loss angle (tan δ) specified at 0.1 (measured at 20 °C, 120 Hz, 50 V).
• Leakage Current — Specified leakage current of 135 µA after application of rated voltage.
• Radial Lead Package — φ10 × 20 mm can, lead spacing 5 mm (±0.5 mm), supplied in bulk (no terminal forming) or bag packing; polar construction.
• Regulatory — RoHS compliant.

Typical Applications

• General-Purpose Electronics — Suited to general-purpose circuit designs requiring 270 µF at 50 V for energy storage or smoothing.
• Through-Hole Assembly — Radial-lead package with 5 mm lead spacing and compact φ10 × 20 mm size simplifies placement in through-hole boards and prototypes.
• High-Temperature Long-Life Designs — 7,000-hour endurance at 105 °C provides specification-level assurance for sustained elevated-temperature operation.
• Frequency-Dependent Ripple Handling — Specified ripple currents at 120 Hz and 10 kHz support designers addressing both low- and high-frequency ripple conditions.

Unique Advantages

• Compact, through-hole form factor: φ10 × 20 mm can offers a small footprint for space-constrained PCBs.
• Clear ripple-current data: Separate low-frequency and high-frequency ripple current ratings simplify thermal and lifetime calculations.
• Long rated life at elevated temperature: 7,000 hours at 105 °C aligns with designs that require extended endurance under heat and load.
• Low impedance: 240 mΩ impedance supports effective decoupling and reduced voltage ripple in power circuits.
• Reliable electrical characteristics: Specified tan δ, leakage current, and capacitance tolerance allow predictable selection and design margins.
• RoHS compliant packaging: Available in bulk (no terminal forming) or bag packing to suit production and prototyping workflows.
