UHW1H391MPD6

The UHW1H391MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UHW series. It is a radial-lead, polarized capacitor specified at 390 µF and 50 V, designed for general-purpose electronic applications.

Key value propositions include low impedance at high frequency, high ripple current handling, and long endurance (10000 hours at 105°C), offering a compact solution where sustained performance and reliability are required.

Key Features

• Capacitance & Voltage: 390 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance.
• Low impedance: Rated impedance of 90 mΩ supports lower AC voltage drop in applications that require high-frequency performance.
• High ripple current: Low-frequency ripple current 1.03 A (120 Hz) and high-frequency ripple current 2.06 A (10 kHz) for robust AC stress handling.
• Loss angle (tan δ): tan δ = 0.10 (measured at 20°C, 120 Hz), indicating controlled dissipation for the rated condition.
• Long endurance: Life rating of 10000 hours at 105°C, supporting extended operating lifetimes under elevated-temperature conditions.
• Operating temperature range: −40°C to +105°C for broad thermal applicability.
• Package & mounting: Radial lead can (φ10×20L) with 5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing.
• Leakage current: Specified leakage current of 195 µA.
• RoHS compliant: Compliant with RoHS requirements.

Typical Applications

• General-purpose electronics — Intended for general-purpose designs requiring a 50 V-rated, 390 µF capacitor with high ripple capability and long endurance.
• High-reliability assemblies — Suitable where extended lifetime at elevated temperature (10000 hours at 105°C) is required.
• Miniature radial-lead designs — Compact φ10×20L can and 5 mm lead spacing make it appropriate for space-conscious radial-lead layouts.

Unique Advantages

• High ripple tolerance: Delivers 1.03 A at 120 Hz and 2.06 A at 10 kHz, enabling dependable AC stress performance within its rated conditions.
• Compact, low-impedance form factor: φ10×20L size with 90 mΩ impedance provides a balance of space savings and electrical performance.
• Long-term reliability: 10000-hour endurance at 105°C supports designs targeting extended operational life under elevated temperatures.
• Measured dissipation: tan δ = 0.10 at 20°C/120 Hz gives predictable loss characteristics for thermal and circuit design calculations.
• Controlled leakage: 195 µA leakage current specification aids in predictable bias performance after application of rated voltage.
• RoHS compliant packaging options: Available in bulk (no terminal forming) or bag packing to support production and procurement needs.
