UHE1H181MPD

The UHE1H181MPD is a radial lead aluminum electrolytic capacitor from Nichicon’s UHE series, designed for general-purpose electronic applications. It offers a compact φ8 × 20 mm can size with 180 μF capacitance at a 50 V rating and is supplied in bulk or bag packing for through‑hole assembly.

Built for low impedance and sustained operation, this part features a measured impedance of 360 mΩ and a rated life of 7000 hours at 105°C, making it suitable where stable filtering and energy storage are required across a −40°C to 105°C operating range. The component is RoHS compliant.

Key Features

• Capacitance & Voltage: 180 μF nominal capacitance with a rated voltage of 50 V and tolerance of −20% to +20%, suitable for a wide range of DC circuits.
• Low Impedance Performance: Specified impedance of 360 mΩ and a dissipation factor (tanδ) of 0.1 at 20°C, 120 Hz for improved voltage stability under load.
• Ripple Current Handling: Rated low-frequency ripple current of 637 mA at 120 Hz and high-frequency ripple current of 910 mA at 10 kHz to support smoothing and decoupling tasks.
• Leakage Current: Low leakage current specified at 90 μA after application of rated voltage, aiding in predictable power loss and standby behavior.
• Long Endurance: Life rating of 7000 hours at 105°C under rated voltage and ripple conditions, aligned with the UHE series’ long-life design.
• Operating Range: Wide operating temperature from −40°C to 105°C for reliable operation across varied environments.
• Radial Lead Package: φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm), radial lead mounting for through‑hole assemblies.
• Compliance & Packaging: RoHS compliant; available in bulk (no terminal forming) or bag packing for production-scale handling.

Typical Applications

• Power Supply Filtering: Smoothing and bulk decoupling in DC power rails where 180 μF at 50 V and low impedance help reduce ripple voltage.
• Decoupling and Energy Storage: Local energy reservoir for regulators and converters that require predictable leakage and ripple current capability.
• General-Purpose Electronic Equipment: Board-level through‑hole capacitor for consumer, industrial, and other general-purpose electronic designs needing long-life capacitors.

Unique Advantages

• Low-impedance design: 360 mΩ impedance and a tanδ of 0.1 at 120 Hz reduce voltage drop and improve transient response in filtering applications.
• High ripple acceptance: Rated ripple currents of 637 mA (120 Hz) and 910 mA (10 kHz) support both mains-frequency and higher-frequency smoothing requirements.
• Long high-temperature life: 7000 hours endurance at 105°C provides predictable aging and reliability for sustained thermal stress.
• Compact radial form factor: φ8 × 20 mm can with 3.5 mm lead spacing fits tightly spaced through‑hole layouts while preserving capacitance density.
• Regulatory compliance: RoHS‑compliant construction simplifies environmental compliance for finished products.
