UHW1K561MHD

The UHW1K561MHD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHW series. It is a polarized, radial-lead unit specified at 560 µF and 80 V, designed for general-purpose electronic applications that require high ripple handling and compact packaging.

Key attributes include low impedance at high frequencies, rated ripple current performance across low and high frequency bands, and a long endurance rating of 12,000 hours at 105 °C—making it suitable for designs needing stable capacitance and thermal robustness within –40 °C to 105 °C.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance at 120 Hz, 20 °C.
• High Ripple Current Capability: Low-frequency ripple current of 1.3 A at 120 Hz and high-frequency ripple current of 2.6 A at 10 kHz, supported by frequency-dependent ripple coefficients in the UHW series.
• Low Impedance and Loss: Rated impedance approximately 110 mΩ and tangent of loss angle (tan δ) of 0.09 measured at 20 °C, 120 Hz, providing efficient AC performance.
• Long Endurance: Life rating of 12,000 hours at 105 °C under specified DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after endurance testing.
• Leakage Current: Specified leakage current of 448 µA (product measurement per data sheet conditions).
• Compact Radial Package: φ12.5 × 35.5 mm body (D: 1.25 cm, L: 3.55 cm) with 5.0 mm lead spacing (±0.5 mm), radial lead mounting for through-hole assemblies.
• Environmental Compliance: RoHS compliant as specified for the UHW series.
• Packaging Options: Available in bulk (no terminal forming) and bag packing for flexible procurement and assembly workflows.

Typical Applications

• General Purpose Electronics: Provides bulk energy storage and smoothing in circuits where high ripple current handling and moderate operating temperature range (–40 °C to 105 °C) are required.
• Power Supply Filtering: Suited for DC bias circuits that demand low impedance and defined ripple current capacity across low and high frequency ranges.
• Industrial and Commercial Equipment: Use in systems that require long endurance (12,000 hours at 105 °C) and stable performance over wide temperature variations.

Unique Advantages

• High ripple-current handling: Rated ripple currents of 1.3 A (120 Hz) and 2.6 A (10 kHz) enable improved AC performance and thermal management in demanding circuits.
• Low impedance at high frequency: Approximately 110 mΩ impedance and low tan δ (0.09) help reduce voltage ripple and loss in high-frequency conditions.
• Long operational life: Endurance rated to 12,000 hours at 105 °C provides predictable long-term behavior and fewer replacement cycles.
• Compact radial form factor: φ12.5 × 35.5 mm body with 5 mm lead spacing delivers a small footprint for through-hole designs without compromising ripple capability.
• RoHS compliant: Meets environmental requirements for restricted substances as specified for the series.
• Flexible packing: Bulk and bag options simplify inventory handling and assembly preparation.
