UPJ1J681MHD6

The UPJ1J681MHD6 is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, offering 680 µF capacitance at a 63 V rating. Designed as a low-impedance device, it is intended for switching power supplies and general-purpose power applications where sustained high-temperature performance is required.

With a polarized aluminum can construction and radial leads, this part delivers defined electrical parameters—capacitance tolerance, ripple current ratings, leakage current limit, and a wide operating temperature range—suitable for engineered power designs.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 63 V working voltage and tolerance of ±20% (measured at 120 Hz, 20°C).
• Low Impedance Design — Engineered for low impedance characteristics appropriate for switching power supply applications, as specified by the UPJ series.
• Temperature Range & Endurance — Operates from -55°C to +105°C with a rated load life of 5000 hours at 105°C.
• Ripple Current Ratings — Rated ripple current of 1.095 A at 120 Hz and 1.61 A at 200 kHz, supporting both low- and high-frequency ripple handling.
• Leakage Current Spec — Leakage current not more than 0.03CV (µA) after one minute's application of rated voltage at 20°C, providing predictable quiescent behavior.
• Loss Angle (tan δ) — Maximum tan δ of 0.08 for the 63 V rating (per UPJ series specifications), giving a quantified dissipation characteristic.
• Package & Mounting — Radial can with radial leads, lead spacing 7.5 mm, and physical dimensions L: 2.5 × D: 1.8 cm for compact board-level integration.
• Environmental Compliance — RoHS-compliant construction.

Typical Applications

• Switching Power Supplies — Low-impedance construction and specified ripple current ratings make this part suitable for bulk filtering and energy storage in switching supplies.
• General-Purpose Power Filtering — Polarized aluminum electrolytic suited for smoothing and decoupling in a wide range of DC power circuits described as general purpose.
• Equipment Requiring High-Temperature Endurance — 5000-hour load life at 105°C supports use in systems that operate at elevated ambient temperatures.

Unique Advantages

• Long High-Temperature Life — 5000 hours at 105°C provides predictable endurance for thermally demanding applications.
• Documented Ripple Performance — Explicit ripple current ratings at 120 Hz and 200 kHz enable designers to size capacitors against both power-line and switching-frequency ripple.
• Quantified Leakage and Loss Characteristics — Leakage current limit of 0.03CV (µA) and tan δ specification (0.08 for 63 V) allow accurate electrical budgeting in designs.
• Compact Radial Can — 2.5 × 1.8 cm package with 7.5 mm lead spacing simplifies through-hole placement while preserving board real estate.
• Regulatory Compliance — RoHS compliance supports environmental and regulatory requirements without additional qualification steps.
