UHW1V561MPD

The UHW1V561MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial-lead can designed for general-purpose power applications. It delivers 560 µF at 35 V with low impedance and elevated ripple-current capability for compact power filtering, decoupling and energy-storage roles.

Engineered for extended operation across a wide temperature range (−40°C to +105°C) and rated for 10,000 hours at 105°C, this RoHS-compliant component balances small case size (φ10 × 20 mm) with measurable electrical performance metrics such as 60 mΩ impedance and a 1.25–2.5 A ripple-current capability depending on frequency.

Key Features

• Capacitance & Voltage — 560 µF nominal capacitance with a rated voltage of 35 V and a tolerance of −20% to +20%.
• High Ripple Current — Low-frequency ripple current 1.25 A (120 Hz) and high-frequency ripple current 2.5 A (10 kHz), supported by frequency coefficients from the UHW series datasheet (e.g., 0.94 at 10 kHz for 220–560 µF).
• Low Impedance & Loss — Typical impedance 60 mΩ and tangent of loss angle (tan δ) 0.11 measured at 20°C, 120 Hz, enabling improved performance in high-frequency circuits.
• Long Endurance — Rated lifetime of 10,000 hours at 105°C under rated DC bias plus ripple, with post-test limits on capacitance, tan δ and leakage current defined by the series specifications.
• Wide Temperature Range — Operates from −40°C to +105°C to accommodate demanding thermal environments.
• Compact Radial Package — φ10 × 20 mm aluminum can, radial lead mounting with 5.0 mm lead spacing (±0.5 mm), suitable for through-hole assemblies.
• Leakage & Polarization — Polarized device with leakage current specified at 196 µA; suitable for designs that require defined leakage performance.
• Packaging Options — Available in bulk (no terminal forming) or bag packing for flexible assembly and procurement.
• Environmental Compliance — RoHS compliant.

Typical Applications

• Power supply filtering — Bulk smoothing and ripple reduction in switching and linear power supplies that benefit from high ripple-current capability and low impedance.
• Decoupling and bulk energy storage — Local energy reservoir for voltage regulation and transient load support in general-purpose electronic systems.
• Industrial and control electronics — Filtering and energy storage in control modules and power subsystems that require long life at elevated temperatures.

Unique Advantages

• Compact size with high ripple capacity — φ10 × 20 mm can delivers 1.25 A to 2.5 A ripple performance, enabling smaller board area for equivalent filtering capability.
• Measured low impedance — 60 mΩ impedance combined with tan δ of 0.11 at 120 Hz supports better high-frequency behavior compared with higher-impedance alternatives.
• Extended high-temperature life — 10,000 hours at 105°C provides predictable long-term performance for thermally demanding designs.
• Through-hole radial mounting — 5.0 mm lead spacing (±0.5 mm) and standard radial can form factor simplify mechanical integration and replacement.
• Clear specification set — Defined leakage current (196 µA), tolerance, ripple ratings and frequency coefficients allow straightforward engineering trade-offs during design.
• RoHS compliant supply options — Available in bulk or bag packing for production flexibility while meeting environmental directives.
