UPJ0J681MPD6

The UPJ0J681MPD6 is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPJ series. It is a radial-lead, polarized device offering 680 µF capacitance at a 6.3 V rating, designed for general-purpose power filtering and decoupling.

Engineered for low impedance and extended high-temperature operation, this part is well suited for switching power supplies and compact electronic designs that require a dependable bulk capacitor with defined ripple performance and long load life.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance at 6.3 V with a tolerance of ±20% (−20% to +20%), providing predictable energy storage for low-voltage power rails.
• Low Impedance Design — Specified as a low-impedance type in the UPJ series, optimized for use in switching power supplies and ripple suppression.
• High-Temperature Endurance — Withstands a 5000-hour load life at +105°C, supporting long-term operation under elevated temperature stress.
• Ripple Performance — Low-frequency ripple current 394.4 mA at 120 Hz and high-frequency ripple current 580 mA at 200 kHz, enabling effective ripple handling across common power conversion frequencies.
• Loss and Leakage — Tangent of loss angle (tanδ) of 0.22 (measured at 20°C, 120 Hz) and a measured leakage current of 128.52 µA, providing electrical parameters for margining and thermal design.
• Compact Radial Package — Aluminum can φ10 × 16 mm (L), radial lead mounting with 5 mm lead spacing (±0.5 mm) for space-conscious PCB layouts.
• Compliance & Availability — RoHS compliant, available in bulk (no terminal forming) or bag packing, and listed as mass production status.

Typical Applications

• Switching Power Supplies — Bulk filtering and ripple suppression in compact switch-mode power supplies where low impedance and defined ripple capability are required.
• General-Purpose Power Filtering — Energy storage and smoothing for low-voltage DC rails in consumer and industrial electronics.
• Space-Constrained Embedded Systems — Compact φ10 × 16 mm can and radial lead format suit designs with limited board area that still require substantial capacitance.

Unique Advantages

• Extended High-Temperature Life — 5000-hour endurance at +105°C reduces the need for early replacement and supports sustained performance in demanding thermal environments.
• Quantified Ripple Ratings — Specified ripple currents at 120 Hz and 200 kHz allow designers to estimate heating and lifetime under real-world power conditions.
• Predictable Electrical Behavior — Published tanδ and leakage current values (measured at 20°C, 120 Hz) enable accurate margining in circuit simulations and thermal budgets.
• Compact, Through-Hole Form Factor — Radial lead package with 5 mm spacing simplifies placement and mechanical retention for through-hole assembly processes.
• Regulatory and Supply Readiness — RoHS compliance and mass-production availability streamline procurement and regulatory planning.
