UHW1A151MDD

The UHW1A151MDD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UHW series. It is a radial-lead, polarized capacitor rated at 150 µF and 10 V, designed for general-purpose electronic applications that require compact size and stable performance across a broad temperature range.

Key value propositions include a small φ5 × 11 mm can, proven endurance at elevated temperature, and measurable ripple-current capability at both low and high frequencies — making it suitable where space and reliable smoothing or decoupling are priorities.

Key Features

• Capacitance & voltage — 150 µF nominal capacitance with a rated voltage of 10 V and a tolerance of −20% to +20%.
• Miniature radial package — Compact φ5 × 11 mm aluminum can with radial leads and 2.0 mm lead spacing (±0.5 mm), suitable for tight PCB footprints.
• High reliability endurance — Specified life/endurance of 7000 hours at elevated temperature conditions.
• Wide operating temperature — Rated for −40 °C to +105 °C to support designs that face varying thermal environments.
• Ripple current handling — Low-frequency ripple current of 180 mA (120 Hz) and high-frequency ripple current of 450 mA (10 kHz) for effective noise and ripple suppression across frequencies.
• Low leakage and loss — Typical leakage current specified at 15 µA and tangent of loss angle (tan δ) of 0.18 (measured at 20 °C, 120 Hz) for predictable electrical behavior.
• Mounting & polarity — Polarized radial-lead design for through-hole mounting in conventional PCB assemblies.
• Compliance & packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible procurement and assembly handling.

Typical Applications

• General-purpose electronic circuits — Serves as a compact polarized electrolytic capacitor option where a 150 µF, 10 V device is required for smoothing or bulk capacitance in confined layouts.
• Compact power modules — Suited to small power supply and regulator circuits that need ripple-current capability at both low and high operating frequencies.
• Board-level decoupling in space-constrained designs — Radial-lead footprint and small can diameter make it applicable where through-hole decoupling is needed but PCB area is limited.

Unique Advantages

• Space-efficient form factor: The φ5 × 11 mm can and short lead spacing reduce PCB area consumption while retaining substantial capacitance.
• Frequency-capable ripple handling: Rated ripple currents at 120 Hz and 10 kHz (180 mA and 450 mA respectively) provide measurable performance across low and high frequency noise components.
• Temperature endurance: Operating range from −40 °C to +105 °C and specified endurance provide predictable behavior in thermally demanding environments.
• Predictable electrical characteristics: Specified tan δ (0.18 at 20 °C, 120 Hz) and low leakage current (15 µA) support stable circuit performance and easier design margining.
• RoHS compliance: Meets RoHS requirements, easing integration into environmentally regulated product lines.
