UHW1A562MHD

The UHW1A562MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series, designed for general-purpose electronics requiring compact size and high ripple handling. It combines a low impedance profile at high frequency with a miniature can-style package for space-constrained power applications.

Key value propositions include a 5.6 mF capacitance at 10 V rating, high ripple current capability across a wide frequency range, RoHS compliance, and a specified endurance of 10,000 hours at 105°C for long-term reliability.

Key Features

• Electrical Performance 5.6 mF (5.6 millifarads) capacitance with a rated voltage of 10 V and a tolerance of ±20%, suited for bulk energy storage and smoothing in low-voltage circuits.
• Low Impedance Specified impedance of 33 mΩ, delivering lower AC voltage ripple and improved performance at higher frequencies.
• High Ripple Current Rated ripple current of 3.502 A at 120 Hz and 4.12 A at 10 kHz, enabling effective handling of both low- and high-frequency ripple components.
• Reliability & Lifetime Endurance rating of 10,000 hours at 105°C and operating temperature range from −40°C to +105°C for sustained performance in elevated-temperature environments.
• Package & Mounting Radial lead can package with 5 mm lead spacing and a compact size of L: 3.55 × D: 1.25 cm, enabling easy through-hole mounting and dense board placement.
• Polarized Design Polarized aluminum electrolytic capacitor tailored for DC applications where polarity is defined.
• Environmental Compliance Compliant with the RoHS directive (2011/65/EU, (EU)2015/863) for restricted substance requirements.

Typical Applications

• Power Supply Filtering — Smooths DC output and reduces ripple in low-voltage linear and switching power supplies, leveraging low impedance and high ripple current ratings.
• DC–DC Converters — Provides bulk energy storage and output stabilization in step-down/step-up regulator stages where compact radial components are required.
• LED Drivers and Lighting Electronics — Handles ripple and transient currents in low-voltage LED driver circuits for improved dimming stability and reduced noise.
• General-Purpose Electronic Modules — Fits space-constrained boards requiring reliable capacitance for decoupling, smoothing, and energy buffering.

Unique Advantages

• Compact, High-Performance Package: The small radial can (L: 3.55 × D: 1.25 cm) reduces board area while retaining high capacitance, supporting denser PCB layouts.
• Superior High-Frequency Behavior: Lower impedance at high frequencies and a higher ripple current at 10 kHz (4.12 A) improve performance in fast-switching power circuits.
• Long-Term Thermal Endurance: 10,000 hours at 105°C provides predictable life characteristics for designs exposed to sustained elevated temperatures.
• Through-Hole Robustness: Radial lead mounting with 5 mm lead spacing simplifies prototyping and through-hole assembly while ensuring mechanical stability.
• Regulatory Compliance: RoHS compliance ensures adherence to restricted substance requirements for global electronics manufacturing.
