UHW1H121MPD

The UHW1H121MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a radial-lead, polarized device specified at 120 µF and 50 V, designed for general-purpose electronic applications that require compact size, sustained ripple handling and long operational life.

Key value comes from a small φ8 × 11.5 mm can with low impedance at higher frequencies, elevated ripple-current capability, a wide operating temperature range (−40 °C to +105 °C) and an endurance rating of 9000 hours at 105 °C.

Key Features

• Capacitance & Rated Voltage — 120 µF nominal capacitance with a rated voltage of 50 V and a capacitance tolerance of −20% to +20%.
• Miniature Radial Package — Compact can size φ8 × 11.5 mm in a radial lead configuration with 3.5 mm lead spacing (±0.5 mm tolerance) for through-hole assemblies.
• High Ripple Current — Low-frequency ripple current 480 mA at 120 Hz and high-frequency ripple current up to 1.2 A at 10 kHz, supported by a low impedance of 360 mΩ.
• Low Loss and Leakage — Specified tangent of loss angle (tan δ) 0.10 at 20 °C, 120 Hz and leakage current rated at 60 µA, enabling efficient filtering and reduced dissipation.
• Wide Temperature & Long Endurance — Operating range −40 °C to +105 °C with life/endurance of 9000 hours at 105 °C under rated bias and ripple conditions.
• Packaging & Compliance — Supplied in bulk or bag packing (no terminal forming) and compliant with RoHS requirements.

Typical Applications

• Power Supply Filtering — Suitable where low impedance and elevated ripple-current capability are required for smoothing and decoupling on DC rails.
• Compact Electronic Modules — Miniature φ8 × 11.5 mm size fits space-constrained through-hole designs that need reliable capacitance density.
• General-Purpose Electronic Circuits — A general-purpose polarized capacitor for a wide range of circuits that require stable performance across −40 °C to +105 °C.

Unique Advantages

• Compact form factor: φ8 × 11.5 mm can delivers 120 µF in a small radial package for space-limited PCBs.
• Enhanced ripple handling: 480 mA at 120 Hz and 1.2 A at 10 kHz ripple-current ratings combined with low impedance (360 mΩ) reduce heating and extend operational stability.
• Long high-temperature life: Rated endurance of 9000 hours at 105 °C provides predictable longevity in elevated-temperature environments.
• Low leakage and dissipation: 60 µA leakage current and tan δ of 0.10 at 120 Hz (20 °C) help maintain efficiency in filtering applications.
• Through-hole friendliness: Radial leaded design with 3.5 mm lead spacing and standard lead diameters simplifies PCB assembly and prototyping.
• Regulatory compliance: RoHS-compliant construction supports environmental requirements for electronic assemblies.
