UHW1K120MDD

The UHW1K120MDD is a miniature, radial-lead aluminum electrolytic capacitor from Nichicon’s UHW series. It is a high-reliability, high-ripple-current component designed for general-purpose electronic applications where compact size and sustained performance are required.

Key electrical characteristics include an 80 V rating, 1200 µF capacitance with ±20% tolerance, and a wide operating temperature range of −40°C to +105°C. The part is RoHS‑compliant and is supplied in bulk or bag packing. Status: End Of Life.

Key Features

• Electrical Rating — Rated voltage 80 V with capacitance specified as 1200 µF and tolerance of −20% to +20%.
• Low Loss — Tangent of loss angle (tanδ) of 0.09 at 20°C, 120 Hz (at the rated voltage condition provided).
• High Ripple Capability — Low-frequency ripple current 124 mA at 120 Hz and high-frequency ripple current 310 mA at 10 kHz, enabling effective smoothing in ripple‑loaded circuits.
• Low Leakage — Leakage current specified at 9.6 µA, supporting low-standby-loss designs.
• Reliability & Lifetime — Endurance rated for 8000 hours at elevated temperature conditions; designed for sustained operation up to 105°C.
• Compact Radial Package — Small form factor φ5 × 11 mm (D × L) with radial leads and 2.0 mm lead spacing (±0.5 mm tolerance) for space-constrained layouts.
• Polarized, Through-Hole Mounting — Radial lead, polarized aluminum can package for straightforward through-hole assembly.
• RoHS Compliance & Packaging Options — RoHS‑compliant construction; available in bulk (no terminal forming) or bag packing.

Typical Applications

• General-Purpose Electronics — Suitable for general-purpose power smoothing and energy storage where a compact, polarized electrolytic is required.
• Power Supply Filtering — High ripple-current capability and low leakage make it appropriate for smoothing and ripple reduction in DC power circuits.
• Compact Power Modules — Small φ5×11 mm package and radial-lead mounting allow integration into space-limited power and control modules.

Unique Advantages

• High Voltage Handling: 80 V rating enables use in higher-voltage subsystems without upsizing the capacitor.
• Compact Size with High Ripple Capacity: φ5×11 mm package delivers substantial ripple current performance (124 mA @120 Hz, 310 mA @10 kHz) in a small footprint.
• Long Endurance at Elevated Temperature: 8000-hour endurance and a −40°C to +105°C operating range support reliable operation in demanding thermal environments.
• Low Loss and Low Leakage: tanδ of 0.09 and leakage current of 9.6 µA help maintain efficiency and reduce standby power draw.
• Simple Through-Hole Integration: Radial-lead, polarized can package with 2.0 mm lead spacing (±0.5 mm) simplifies PCB layout and assembly for through-hole designs.
