UPJ0J681MPD

The UPJ0J681MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPJ series, offering a 680 µF capacitance at a 6.3 V rating in a compact φ8×20L can. Designed for low impedance and high reliability, this part is tailored for power-filtering and energy-storage duties in compact switching power designs and general-purpose electronics.

Key attributes include a wide operating temperature range of -55°C to 105°C, a rated endurance of 3000 hours at 105°C for the φ8 case, and ripple-current capability specified at both low and high frequencies—making it suitable where stable bulk capacitance and ripple handling are required.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 6.3 V nominal voltage and capacitance tolerance of -20% to +20%.
• Low Loss / Loss Angle — tanδ (DF) specified at 0.22 measured at 20°C, 120 Hz, supporting efficient AC performance in filtering applications.
• Ripple Current Performance — Low-frequency ripple current of 411.4 mA at 120 Hz and high-frequency ripple current of 605 mA at 200 kHz, enabling effective smoothing under varying switching conditions.
• Leakage Current — Product-specified leakage current of 128.52 µA at rated conditions.
• High Temperature Endurance — Rated life of 3000 hours at 105°C for the φ8 case size, reflecting sustained performance under elevated-temperature load.
• Package & Mounting — Radial lead can (φ8×20L) with 3.5 mm lead spacing (±0.5 mm), supplied in bulk (no terminal forming) or bag packing for flexible assembly workflows.
• Environmental Compliance — RoHS compliant as indicated in product data.

Typical Applications

• Switching Power Supplies — Bulk filtering and output smoothing where low impedance and ripple-current capability improve voltage stability.
• DC–DC Converters — Input/output decoupling in compact converters that require high capacitance in a small radial package.
• Industrial Power Modules — Energy storage and ripple suppression in control and power distribution modules operating across -55°C to 105°C.
• Consumer and Embedded Electronics — General-purpose power filtering in compact assemblies requiring a reliable polarized capacitor.

Unique Advantages

• Low-Impedance Design: Specified low tanδ and series design intent for switching supplies help reduce AC losses and improve transient response.
• Broad Ripple Handling: Explicit ripple current ratings at 120 Hz and 200 kHz let designers size capacitors for both line-frequency and high-frequency switching environments.
• Compact, Serviceable Form Factor: φ8×20L radial can with standard 3.5 mm lead spacing provides a compact footprint while remaining straightforward to replace or prototype with through-hole assemblies.
• High-Temperature Endurance: 3000-hour rating at 105°C for the φ8 case supports sustained operation in hot enclosures and elevated ambient conditions.
• Regulatory Compliance: RoHS compliance addresses environmental requirements for modern electronic assemblies.
• Ready for Production: Listed as mass production status with bulk or bag packing options for production-scale procurement and handling.
