UHD1A681MPD

The UHD1A681MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UHD series, designed for circuits that require high ripple handling and low impedance across frequency. It provides 680 µF capacitance at a 10 V rating with a polarized radial-can package and is intended for general-purpose electronic power designs.

Key value propositions include high allowable ripple current, a compact φ8×15 mm case, and robust thermal endurance (–40 °C to 105 °C, 3000 hours at 105 °C), making it suitable for compact power-supply smoothing and decoupling applications where space and ripple performance matter.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a 10 V rated voltage and a capacitance tolerance of −20% to +20% (measured at 20 °C, 120 Hz).
• Low Impedance & High Ripple Capability — Series emphasis on lower impedance at high frequencies; specified ripple currents of 746.3 mA at 120 Hz and 995 mA at 100 kHz support demanding ripple conditions.
• Loss and Leakage Characteristics — Tangent of loss angle (tanδ) is 0.19 (20 °C, 120 Hz), and leakage current is specified at 68 µA, supporting efficient charge/discharge behavior in power circuits.
• Temperature Range & Endurance — Operating range −40 °C to 105 °C with endurance rated at 3000 hours at 105 °C (φ8 case), enabling reliable operation in elevated-temperature environments.
• Compact Radial Package — φ8 × 15 mm can with 3.5 mm lead spacing (±0.5 mm tolerance) and radial lead mounting for through-hole assemblies; available in bulk or bag packing.
• RoHS Compliant — Conforms to RoHS directive per product information.

Typical Applications

• Power Supply Output Filtering — Smooths and filters output rails in power supplies, leveraging high ripple current ratings and low impedance to reduce voltage ripple.
• Decoupling for DC–DC Converters — Provides bulk decoupling and energy buffering for switching regulators where compact, high-capacitance solutions are required.
• General-Purpose Electronic Circuits — Suitable for consumer and industrial boards requiring a compact polarized capacitor with reliable thermal endurance and controlled loss/ leakage performance.

Unique Advantages

• High ripple tolerance: Specified ripple current values (746.3 mA @120 Hz, 995 mA @100 kHz) enable effective handling of AC stress on DC rails.
• Small footprint, high capacitance: 680 µF in a φ8 × 15 mm can saves board space without sacrificing bulk capacitance.
• Wide operating temperature and proven endurance: −40 °C to 105 °C operation and 3000-hour life at 105 °C provide predictable long-term performance in elevated-temperature applications.
• Controlled dissipation and leakage: tanδ of 0.19 and 68 µA leakage support efficient energy storage and minimize steady-state losses.
• Radial lead convenience: 3.5 mm lead spacing and standard radial can packaging simplify through-hole assembly and prototyping workflows; available in bulk or bag packing to suit production needs.
