UHD1H151MPD

The UHD1H151MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UHD series, optimized for low impedance at high frequencies and elevated ripple current capability. With a nominal capacitance of 150 µF and a rated voltage of 50 V, it targets general-purpose electronic designs that require compact, robust bulk and decoupling capacitance.

Key characteristics include a compact φ10 × 12.5 mm can, a wide operating temperature range of −40 °C to +105 °C, and an endurance rating of 4000 hours at 105 °C, making it suitable for assemblies that demand sustained performance under heat and ripple stress.

Key Features

• Capacitance & Voltage — 150 µF nominal capacitance with tolerance ±20% and a rated voltage of 50 V, delivering predictable bulk energy storage for general-purpose circuits.
• Low Loss / High Frequency Performance — Tangent of loss angle (tan δ) 0.10 measured at 20 °C, 120 Hz, and series design notes indicate lower impedance at high frequency ranges for improved decoupling behavior.
• High Ripple Current Capability — Rated low-frequency ripple current of 685.3 mA at 120 Hz and high-frequency ripple current of 979 mA at 100 kHz, supporting sustained ripple conditions.
• Leakage Current — Specified leakage current of 75 µA (after standard charging conditions), suitable for circuits requiring controlled standby leakage.
• Robust Thermal Endurance — Operating temperature range −40 °C to +105 °C with a rated life of 4000 hours at 105 °C under D.C. bias plus rated ripple current.
• Mechanical / Mounting — Radial lead can, size φ10 × 12.5 mm (D × L), lead spacing 5.0 mm with a lead-spacing tolerance of ±0.5 mm; available in bulk (no terminal forming) or bag packing.
• Compliance — RoHS compliant and in mass production.

Typical Applications

• General-purpose power filtering — Provides bulk capacitance and ripple handling for power rails where a 150 µF, 50 V radial electrolytic fits the board layout.
• Decoupling and smoothing — Low tan δ and reduced high-frequency impedance support smoothing of supply transients and decoupling in compact assemblies.
• Embedded and industrial electronics — Compact φ10 × 12.5 mm package and wide temperature range (−40 °C to +105 °C) suit space-constrained boards operating in varied environments.

Unique Advantages

• Measured ripple-current performance — Explicitly rated ripple currents at 120 Hz (685.3 mA) and 100 kHz (979 mA) enable confident thermal and lifetime planning under AC stress.
• Compact radial can — φ10 × 12.5 mm footprint and 5.0 mm lead spacing simplify placement in tight layouts while preserving required capacitance.
• High-temperature endurance — 4000 hours at 105 °C under rated conditions provides a defined reliability baseline for designs subjected to elevated operating temperatures.
• Low dissipation — tan δ of 0.10 (20 °C, 120 Hz) indicates low dielectric loss for reduced self-heating during operation.
• Assembly-ready packing options — Available in bulk (no terminal forming) or bag packing to match production handling preferences.
• Regulatory compliance — RoHS compliant for deployments requiring restricted-substance adherence.

Why Choose UHD1H151MPD?

The UHD1H151MPD combines compact packaging with clearly specified electrical and thermal characteristics—150 µF at 50 V, defined ripple-current ratings across low and high frequencies, low tan δ, and a 4000-hour endurance at 105 °C—making it a practical choice for engineers needing predictable performance in general-purpose power and decoupling applications. Its radial can form factor and standard 5.0 mm lead spacing simplify PCB layout and assembly choices.

This part is appropriate for design teams and procurement sourcing components for mid-volume to mass-production projects that require documented ripple handling, thermal endurance, and RoHS compliance backed by Nichicon's UHD series specifications.
