UHV1E681MPD

The UHV1E681MPD is a Nichicon UHV-series aluminum electrolytic capacitor in a radial-lead can. It provides 680 µF capacitance at a 25 V rating with low impedance and high ripple-current capability targeted for general-purpose electronic power filtering and bulk decoupling.

Designed for compact, through-hole assemblies, this radial lead capacitor balances a small φ10 × 16 mm case with a 6000-hour endurance at 105°C, making it suitable for designs requiring sustained ripple handling and reliable performance across a wide temperature range.

Key Features

• Capacitance & Voltage — 680 µF nominal capacitance with a rated voltage of 25 V and capacitance tolerance of −20% to +20%.
• Low Impedance — Rated impedance of 95 mΩ supports stable performance under AC ripple conditions.
• High Ripple Current — Low-frequency ripple current 1.089 A at 120 Hz and high-frequency ripple current 1.815 A at 100 kHz for demanding power applications.
• Loss Angle (tan δ) — tan δ of 0.13 measured at 20°C and 120 Hz for predictable ESR-related behavior.
• Long Endurance — Rated life of 6000 hours at 105°C under DC bias plus ripple current, with defined limits for capacitance change, tan δ and leakage current.
• Temperature Range — Operates from −40°C to +105°C for broad environmental compatibility.
• Compact Radial Package — φ10 × 16 mm can with 5 mm lead spacing (±0.5 mm) and radial lead mounting for easy through-hole assembly; available in bulk or bag packing.
• RoHS Compliant & Production Ready — RoHS-compliant construction and listed as in mass production.

Typical Applications

• Power Supply Filtering — Bulk decoupling and smoothing where high ripple current and low impedance improve rail stability.
• DC–DC Converter Output — Provides energy storage and ripple suppression in compact through-hole designs requiring high-frequency performance.
• General-Purpose Electronics — Radial lead format and RoHS compliance make it suitable for a wide range of consumer and industrial general-purpose circuits.

Unique Advantages

• High ripple-handling capability: Specified ripple currents of 1.089 A (120 Hz) and 1.815 A (100 kHz) reduce temperature rise and extend operating life in ripple-intensive circuits.
• Low impedance: 95 mΩ impedance enhances transient response and reduces voltage drop under load.
• Compact radial package: φ10 × 16 mm case with 5 mm lead spacing delivers a small footprint for through-hole assemblies without sacrificing capacitance.
• Extended endurance at elevated temperature: 6000 hours at 105°C supports long-term reliability in continuous-use power applications.
• Wide operating temperature: −40°C to +105°C supports deployment across diverse environmental conditions.
• Production availability: Mass-production status and RoHS compliance help ensure supply continuity and regulatory compatibility.
