UHD1E681MPD

The UHD1E681MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UHD series. It is a radial-lead, polarized device specified at 680 μF and 25 V, designed for general-purpose electronic applications that require compact bulk capacitance with strong ripple-handling capability.

Built for demanding operating conditions, the UHD1E681MPD combines low impedance at higher frequencies with a compact φ10×20 mm can, wide operating temperature range of −40°C to +105°C and a rated endurance of 4000 hours at 105°C.

Key Features

• Capacitance & Voltage — 680 μF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20% for predictable bulk energy storage.
• Low Impedance / High Ripple Capability — UHD series design provides lower impedance at high frequency and rated ripple currents of 1.365 A at 120 Hz and 1.82 A at 100 kHz for improved smoothing and decoupling performance.
• Temperature & Endurance — Rated for operation from −40°C to +105°C and endurance of 4000 hours at 105°C, supporting reliable operation in elevated-temperature environments.
• Leakage and Loss Characteristics — Specified leakage current of 170 μA and a tangent of loss angle (tan δ) of 0.14 (measured at 20°C, 120 Hz) to help manage standby losses and dissipation.
• Compact Radial Package — φ10 × 20 mm case with 5 mm lead spacing and radial lead mounting for through-hole assemblies where space is constrained.
• Compliance and Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing for flexible handling in production.

Typical Applications

• Power Supply Filtering — Provides bulk capacitance and ripple absorption for general-purpose power rails up to 25 V, leveraging its high ripple current rating.
• DC‑DC Converter Output — Compact φ10×20 mm package and low high-frequency impedance make it suitable for output smoothing and decoupling in compact converter designs.
• General Purpose Electronics — Useful in a wide range of assemblies requiring a polarized electrolytic capacitor with extended temperature range and multi-khour endurance.

Unique Advantages

• High Ripple Endurance: Rated ripple currents of 1.365 A (120 Hz) and 1.82 A (100 kHz) support sustained AC content handling without oversizing the capacitor.
• Low High‑Frequency Impedance: UHD series construction reduces impedance at higher frequencies, improving filtering effectiveness in compact designs.
• Compact Footprint: φ10×20 mm case with 5 mm lead spacing delivers substantial capacitance in a small radial-leaded package for space-constrained PCBs.
• Wide Temperature Range: −40°C to +105°C rating and 4000 h endurance at 105°C provide predictable life under elevated-temperature operating profiles.
• Low Leakage and Defined Loss: 170 μA leakage and tan δ = 0.14 (20°C, 120 Hz) give designers concrete parameters for energy management and thermal budgeting.
• RoHS Compliant Packaging Options: Available in bulk or bag packing to match assembly and inventory workflows while meeting RoHS requirements.
