UHW1H151MPD

The UHW1H151MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead package from Nichicon's UHW series. It delivers 150 µF at 50 V in a compact φ8 × 15 mm can with a radial lead spacing of 3.5 mm, aimed at general-purpose electronic designs that require compact size and elevated ripple capability.

Designed for extended operation across a wide temperature range, this polarized capacitor provides a combination of low impedance, measurable loss angle, and defined ripple current ratings for both low- and high-frequency applications.

Key Features

• Capacitance & Voltage: 150 µF nominal capacitance with a rated voltage of 50 V and a tolerance of −20% to +20%.
• Low impedance and loss: Specified impedance of 170 mΩ and tanδ (loss tangent) of 0.1 measured at 20°C, 120 Hz, supporting improved AC performance.
• High ripple capability: Low-frequency ripple current of 640 mA at 120 Hz and high-frequency ripple current of 1.6 A at 10 kHz, enabling effective ripple handling across different operating frequencies.
• Leakage current: Specified leakage current of 75 µA, measured under rated conditions.
• Wide operating temperature and endurance: Operational range from −40°C to +105°C with a rated life/endurance of 10,000 hours at 105°C.
• Compact radial package: φ8 × 15 mm can (D: 0.8 cm × L: 1.5 cm), radial lead mounting with 3.5 mm lead spacing (±0.5 mm), suitable for through-hole PCB layouts.
• Packaging options: Available in Bulk (no terminal forming) or Bag packing to suit different assembly workflows.
• Regulatory compliance: RoHS compliant.

Typical Applications

• General-purpose electronics: Compact designs that need bulk capacitance with elevated ripple-handling capability in a radial through-hole form factor.
• Power supply filtering: Local energy storage and smoothing where 150 µF at 50 V and specified ripple ratings meet system requirements.
• High-frequency circuits: Applications requiring defined high-frequency ripple current performance (1.6 A at 10 kHz) alongside low impedance.

Unique Advantages

• Compact footprint with robust ripple handling: φ8 × 15 mm can provides 150 µF at 50 V while supporting up to 1.6 A ripple at 10 kHz, enabling space-efficient designs without sacrificing ripple capability.
• Measurable AC performance: Low impedance (170 mΩ) and tanδ = 0.1 (20°C, 120 Hz) give predictable behavior for decoupling and filtering applications.
• Wide temperature endurance: −40°C to +105°C rating and 10,000-hour life at 105°C support sustained operation in demanding thermal environments.
• Through-hole convenience: Radial lead format with 3.5 mm lead spacing (±0.5 mm) simplifies PCB placement and manual or wave-solder assembly processes.
• Controlled leakage: Low specified leakage current (75 µA) helps maintain efficiency in DC-biased circuits.
• RoHS compliant: Meets RoHS requirements for restricted substances.
