UHW1A561MPD

The UHW1A561MPD is a radial-lead aluminum electrolytic capacitor in Nichicon’s UHW series, offering 560 µF capacitance at a 10 V rating in a compact φ8 × 11.5 mm can. It combines miniature sizing with series-level attributes — lower impedance at high frequency and high ripple-current capability — for general-purpose electronic power circuits.

Designed for engineers needing compact, high-ripple filtering components, this part delivers measurable performance advantages in small power supplies and other board-level decoupling or smoothing roles while meeting RoHS requirements and shipping in bulk/bag packaging for production use.

Key Features

• Capacitance & Voltage: 560 µF nominal capacitance with a 10 V rated voltage and tolerance of -20% to +20% for predictable bulk energy storage and smoothing.
• High Ripple Current: Rated for 600 mA at 120 Hz (low frequency) and 1.2 A at 10 kHz (high frequency), enabling effective damping of AC ripple in power stages and DC–DC converter outputs.
• Low Impedance: Specified impedance of 360 mΩ, supporting stable performance at higher frequencies and reducing voltage drop under ripple conditions.
• Thermal Endurance: Operating range from -40°C to 105°C with an endurance rating of 9000 hours at 105°C, supporting extended life in elevated-temperature applications.
• Compact Radial Package: φ8 × 11.5 mm can with 3.5 mm lead spacing (±0.5 mm) and radial lead mounting for easy through-hole placement and robust mechanical connection.
• Electrical Quality: tanδ (DF) of 0.18 measured at 20°C, 120 Hz and leakage current of 56 µA, providing defined loss and leakage characteristics for design calculations.
• Regulatory & Production Status: RoHS compliant and listed as mass production, available in bulk/no terminal forming bag packing for assembly workflows.

Typical Applications

• Power-supply filtering: Use for output smoothing and bulk decoupling in compact linear and switching power supplies where high ripple handling and low impedance are required.
• DC–DC converter outputs: Supports high-frequency ripple currents (1.2 A at 10 kHz), making it suitable for board-level energy storage on converter outputs.
• General-purpose electronic equipment: Fits a range of consumer and industrial designs requiring a compact polarized electrolytic for decoupling, hold-up, or smoothing functions.

Unique Advantages

• Measured high-frequency performance: Lower impedance at high frequencies and a specified 1.2 A ripple current at 10 kHz improve filtering effectiveness in compact layouts.
• Compact footprint: φ8 × 11.5 mm size with radial leads enables high-density placement on through-hole boards where space is limited.
• Predictable thermal life: Endurance specified at 9000 hours at 105°C gives designers a quantifiable metric for lifetime planning in elevated-temperature environments.
• Defined loss and leakage specs: tanδ of 0.18 and leakage current of 56 µA provide clear electrical parameters for stability and standby current budgeting.
• Production-ready packaging: Supplied in bulk/bag packing and designated mass production status to support procurement and volume assembly.
