UHW1H122MHD

The UHW1H122MHD is a radial lead aluminum electrolytic capacitor from Nichicon's UHW series, offering a compact, can-style package with high ripple current capability and long endurance. It is designed as a general-purpose power component where bulk capacitance, frequency performance and reliability are required.

Key attributes include 1.2 mF capacitance at 50 V, low impedance characteristics in the high-frequency range, and a rated lifetime of 10,000 hours at 105°C, making it suitable for a wide range of general-purpose electronic power applications.

Key Features

• Capacitance & Voltage — 1.2 mF (1200 µF) nominal capacitance with a rated voltage of 50 V and capacitance tolerance of -20% to +20%.
• High Ripple Current — Low-frequency ripple current of 1.962 A (120 Hz) and high-frequency ripple current of 3.27 A (10 kHz), supporting demanding AC/ripple conditions in power circuits.
• Low Impedance at Frequency — Rated impedance of 63 mΩ and documented lower impedance in the high-frequency range to improve filtering and decoupling performance.
• Endurance & Temperature Range — Lifetime specified at 10,000 hours at 105°C; operating temperature range from -40°C to +105°C for sustained performance in elevated-temperature environments.
• Electrical Losses & Leakage — Dissipation factor (tan δ) specified as 0.1 (measured at 20°C, 120 Hz) and leakage current of 600 µA, aiding predictable power-loss budgeting.
• Compact Radial Package — Can-style radial lead package sized φ16 × 25L with 7.5 mm lead spacing (±0.5 mm), available in bulk (no terminal forming) or bag packing for flexible assembly handling.
• RoHS Compliant — Manufactured to comply with RoHS requirements.

Typical Applications

• General-purpose power filtering — Bulk energy storage and smoothing in 50 V circuits where 1.2 mF capacitance and high ripple capacity reduce voltage ripple and improve regulator stability.
• Switching power supplies — Input or output decoupling where high-frequency ripple handling (3.27 A at 10 kHz) and low impedance help maintain stable supply rails.
• Industrial electronics — General-purpose filtering and energy buffering in equipment operating across -40°C to +105°C, leveraging the 10,000 h endurance rating at 105°C.

Unique Advantages

• High ripple handling — Combines 1.962 A at 120 Hz and 3.27 A at 10 kHz ripple specs to support both low- and high-frequency ripple environments.
• Frequency-optimized performance — Designed for lower impedance in the high-frequency range, improving decoupling effectiveness on switching nodes.
• Long-term reliability — 10,000-hour endurance at 105°C provides predictable life and performance in elevated-temperature applications.
• Compact form factor — φ16 × 25L radial can with 7.5 mm lead spacing delivers 1.2 mF capacitance in a small footprint for space-constrained boards.
• Predictable electrical characteristics — Specified tan δ (0.1 at 20°C/120 Hz), impedance (63 mΩ) and leakage current (600 µA) simplify thermal and loss calculations during design.
• RoHS compliance — Conforms to RoHS directive for use in regulated product assemblies.
