UHW1C561MPD

The UHW1C561MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial lead can, designed for general-purpose electronic applications. It combines a compact φ8×15 mm case with high ripple-current capability and low impedance to support power smoothing and decoupling in space-constrained designs.

Key attributes include 560 µF capacitance at 16 V, a wide operating temperature range of −40°C to +105°C, and an endurance rating of 10,000 hours at 105°C—making it suitable for designs that demand long-term performance under elevated temperature and ripple stress.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a rated voltage of 16 V and tolerance of −20% to +20%, providing bulk energy storage for low-voltage rails.
• High Ripple Current — Low-frequency ripple current of 800 mA (120 Hz) and high-frequency ripple current of 1.6 A (10 kHz) to handle significant AC stress on DC rails.
• Low Impedance — Rated impedance of 170 mΩ helps reduce voltage ripple and improve transient response in power circuits.
• Thermal and Lifetime Performance — Rated for −40°C to +105°C operation with an endurance of 10,000 hours at 105°C under rated bias and ripple conditions.
• Dielectric Loss — Tangent of loss angle (tan δ) of 0.15 measured at 20°C, 120 Hz, enabling predictable dissipation characteristics.
• Leakage Current — Specified leakage current of 89.6 µA, supporting low-standby current designs.
• Package & Mounting — Radial lead can, φ8×15 mm size with 3.5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for straightforward through-hole assembly.
• Compliance — RoHS compliant for regulatory alignment in modern electronic assemblies.

Typical Applications

• Power Supply Filtering — Bulk capacitance and high ripple-current capability provide effective smoothing for low-voltage DC power rails.
• DC-DC Converter Output — Low impedance and high-frequency ripple rating support decoupling and stabilization of converter outputs in compact assemblies.
• General-Purpose Electronics — Small case size and long endurance suit consumer, industrial, and instrumentation boards where space and reliability are priorities.

Unique Advantages

• High Ripple Handling: Specified for 800 mA at 120 Hz and 1.6 A at 10 kHz, enabling reliable operation under significant AC stress.
• Compact Footprint: φ8×15 mm radial can with 3.5 mm lead spacing delivers substantial capacitance in a small through-hole package.
• Extended Endurance: 10,000 hours at 105°C supports long-term reliability in thermally demanding environments.
• Predictable Electrical Losses: tan δ = 0.15 (20°C, 120 Hz) gives clear expectations for dissipation and heating during operation.
• Low Leakage Current: 89.6 µA leakage current helps minimize standby power consumption in battery-assisted or low-power systems.
• Regulatory Compliance: RoHS conformity simplifies integration into contemporary assemblies requiring restricted-substance compliance.
