UHV1A681MPD

The UHV1A681MPD is an aluminum electrolytic capacitor in a radial-lead can designed for general-purpose electronic applications. It combines a compact φ8 × 11.5 mm package with low impedance and high ripple-current capability to support power-management and filtering needs in through-hole assemblies.

Key performance highlights include 680 µF capacitance at 10 V, a low loss tangent (tanδ 0.18 at 20°C/120 Hz), rated ripple currents up to 990 mA at high frequency, and a 6000-hour endurance at 105°C for extended operating life.

Key Features

• Capacitance & Voltage: 680 µF nominal capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in low-voltage designs.
• Low Loss / Low Impedance: tanδ = 0.18 (20°C, 120 Hz) and specified impedance of 181 mΩ, supporting improved performance in AC ripple and transient conditions.
• High Ripple Current: 594 mA at 120 Hz (low frequency) and 990 mA at 100 kHz (high frequency), enabling effective ripple handling across a wide frequency range.
• Long Endurance: Rated for 6000 hours at 105°C under rated DC bias plus ripple, providing a predictable lifetime for thermally demanding applications.
• Compact Radial Package: φ8 × 11.5 mm can with radial leads and 3.5 mm lead spacing (±0.5 mm), suitable for through-hole mounting where board space is limited.
• Low Leakage Current: Specified leakage current of 68 µA after rated voltage application, helping maintain efficiency in DC circuits.
• RoHS Compliant & Packaging: RoHS-compliant construction; supplied in bulk/bag packing (no terminal forming).

Typical Applications

• Power supply smoothing: Bulk capacitance and high ripple-current capability support smoothing and filtering in low-voltage DC power rails.
• Decoupling and energy storage: Compact 680 µF value in a radial package provides local energy reservoir for transient events in board-level designs.
• Industrial and general-purpose electronics: Wide operating range (−40°C to +105°C) and long endurance make it suitable for general-purpose assemblies requiring reliable electrolytic performance.

Unique Advantages

• High ripple handling: Dual-spec ripple ratings (594 mA at 120 Hz and 990 mA at 100 kHz) accommodate both low- and high-frequency ripple environments.
• Low impedance for better filtering: 181 mΩ impedance and low tanδ reduce AC voltage drop and heat generation under ripple load.
• Durable thermal endurance: 6000 hours at 105°C provides predictable aging characteristics for designs exposed to elevated temperatures.
• Space-efficient through-hole form factor: φ8 × 11.5 mm can with standard radial lead spacing fits compact boards while retaining through-hole robustness.
• Controlled leakage: 68 µA leakage current helps preserve efficiency in DC circuits and minimizes parasitic losses.
• RoHS compliance: Environmentally compliant construction for regulatory alignment in commercial and industrial products.
