UHW1E681MPD

The UHW1E681MPD is a miniature, high-reliability aluminum electrolytic capacitor in a radial‑lead can designed for general-purpose power applications. It delivers 680 µF capacitance at a 25 V rating with polarized radial leads and a compact φ10 × 16 mm package.

Engineered for sustained ripple handling and long life at elevated temperature, this UHW-series device targets designs that require low impedance, high ripple current capability and operational stability from –40 °C to +105 °C.

Key Features

• Capacitance and Voltage: 680 µF nominal capacitance with a rated voltage of 25 V and a capacitance tolerance of −20% to +20%.
• High ripple current capability: Low-frequency ripple current 1.2 A (120 Hz) and high-frequency ripple current 2.0 A (10 kHz), supporting applications with significant AC stress.
• Low impedance: Typical impedance of 90 mΩ, helping reduce voltage ripple and losses in power circuits.
• Loss tangent (tan δ): tan δ of 0.13 measured at 20 °C, 120 Hz, supporting predictable dissipation characteristics.
• Long endurance: Rated for 10,000 hours at 105 °C, providing extended operational life under high-temperature conditions.
• Wide operating temperature range: −40 °C to +105 °C for reliable performance across common environmental extremes.
• Compact radial-lead package: φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• RoHS compliant: Meets RoHS requirements for materials compliance.

Typical Applications

• Power supply filtering: Bulk and decoupling capacitor for DC power rails where 680 µF and low impedance reduce output ripple and stabilize regulators.
• Switching regulator support: Input/output smoothing for DC–DC converters that require high ripple current capability at both low and high frequencies.
• Industrial controls and instrumentation: Energy storage and transient suppression in general-purpose industrial and instrumentation electronics operating across a wide temperature range.

Unique Advantages

• High ripple tolerance: Specified ripple currents of 1.2 A (120 Hz) and 2.0 A (10 kHz) let designers handle both low- and high-frequency ripple without oversized components.
• Low-loss operation: 90 mΩ impedance and tan δ of 0.13 (at 120 Hz, 20 °C) translate into lower heat generation and improved efficiency in power circuits.
• Small footprint: φ10 × 16 mm radial can provides a compact solution for space-constrained PCBs while retaining substantial capacitance.
• Extended life at high temperature: 10,000-hour endurance rating at 105 °C supports designs requiring long-term reliability under thermal stress.
• Flexible supply formats: Available in bulk (no terminal forming) or bag packing to suit automated or manual assembly processes.
• Regulatory compliance: RoHS status ensures material compliance for global product builds.
