UHW1E561MPD

The UHW1E561MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can, part of Nichicon’s UHW series. It delivers 560 µF at 25 V in a compact φ8 × 20 mm package designed for applications that require low impedance and elevated ripple capability.

With a wide operating temperature range from −40 °C to 105 °C and a rated endurance of 10,000 hours at 105 °C, this part is suited for general-purpose power filtering, smoothing and decoupling where long-term stability in a small footprint is required.

Key Features

• Capacitance & Rated Voltage: 560 µF capacitance rated at 25 V with tolerance −20% to +20%.
• Low impedance: Impedance specified at 120 mΩ for improved high-frequency performance in compact designs.
• High ripple capability: Low-frequency ripple current 980 mA (120 Hz) and high-frequency ripple current 1.96 A (10 kHz) to support power supply filtering and dynamic loads.
• Thermal endurance: Operating temperature −40 °C to 105 °C with a lifetime of 10,000 hours at 105 °C under rated conditions.
• Loss characteristics: Dissipation factor (tan δ) 0.13 measured at 20 °C, 120 Hz.
• Leakage current: Specified leakage current of 140 µA after application of rated voltage.
• Compact radial package: Can size φ8 × 20 mm, radial lead spacing 3.5 mm (±0.5 mm), available in bulk or bag packing; standard radial-lead mounting.
• Regulatory compliance: RoHS compliant.

Typical Applications

• Power supply smoothing and decoupling: Low impedance and high ripple current make it suitable for AC ripple smoothing and output filtering in compact power supplies and DC–DC converters.
• Power-management modules: Supports high-frequency ripple currents for filtering in regulator and converter circuits where board space is limited.
• Industrial and general-purpose electronics: Wide temperature range and 10,000-hour endurance at 105 °C provide reliable performance in prolonged-duty applications.
• Consumer electronics: Compact φ8 × 20 mm can size and radial-lead format fit space-constrained boards while maintaining ripple and leakage performance.

Unique Advantages

• High ripple handling in a small footprint: Delivers 980 mA (120 Hz) and 1.96 A (10 kHz) ripple capability in a φ8 × 20 mm package, enabling compact board layouts without sacrificing filtering performance.
• Low-loss operation: 120 mΩ impedance and tan δ of 0.13 (20 °C, 120 Hz) help reduce heat generation and maintain efficiency under AC stress.
• Long-term reliability: Rated for 10,000 hours at 105 °C, providing predictable life performance for continuous operation applications.
• Wide temperature range: −40 °C to 105 °C operating range supports designs exposed to varying thermal environments.
• Standard radial-lead mounting: 3.5 mm lead spacing (±0.5 mm) simplifies PCB layout and mechanical assembly for through-hole designs.
• Regulatory compliance: RoHS compliant for use in regions and products requiring restricted substances conformance.
