UPJ1H680MPD

The UPJ1H680MPD is a Nichicon UPJ series aluminum electrolytic capacitor specified at 68 µF and 50 V in a radial-lead can. Engineered for low impedance and high reliability, this φ8 × 11.5 mm radial unit is well suited for board-level power applications, including switching power supplies and general-purpose power filtering. It is offered in bulk or bag packing and is in mass production.

Key Features

• Capacitance & Voltage — 68 µF nominal at a rated voltage of 50 V with ±20% tolerance (measured at 120 Hz, 20°C).
• Low Impedance Performance — UPJ series design emphasizes low impedance, making it suitable where ripple handling and stable impedance at frequency are important.
• Ripple Current Capability — Rated ripple current: 130 mA at 120 Hz and 255 mA at 200 kHz, supporting common power-supply ripple conditions.
• Thermal Range & Endurance — Operating temperature range −55°C to +105°C with a rated lifetime of 3000 hours at 105°C for the φ8 case size.
• Leakage Current — Specified leakage current of 102 µA after application of rated voltage at 20°C.
• Mechanical & Mounting — Radial lead, polarized can with φ8 body, lead spacing 3.5 mm (±0.5 mm), and physical size 1.15 × 0.8 cm (L × D).
• Compliance & Packaging — RoHS compliant; available in bulk (no terminal forming) or bag packing.

Typical Applications

• Switching Power Supplies — Low-impedance behavior and specified ripple current make this capacitor appropriate for smoothing and energy storage in switching regulators.
• Board-Level Power Filtering — Through-hole radial format and compact φ8 size provide an easy-to-place option for input/output decoupling and bulk filtering on power boards.
• General-Purpose Power Circuits — Polarized aluminum electrolytic suitable for a wide range of general-purpose power applications where a 50 V, 68 µF value is required.
• High-Temperature Environments — Rated to operate to +105°C with a specified 3000-hour endurance at that temperature for the φ8 case, supporting elevated-temperature designs.

Unique Advantages

• Low-impedance design — Reduces voltage ripple and improves stability in power-supply rails by delivering lower impedance across relevant frequencies.
• Temperature endurance — 3000-hour rating at 105°C for the φ8 case provides predictable long-term behavior in thermally demanding applications.
• Measured ripple performance — Published ripple-current ratings at 120 Hz and 200 kHz allow designers to evaluate thermal and life impacts under real operating conditions.
• Compact radial package — φ8 × 11.5 mm can with 3.5 mm lead spacing offers a space-efficient, through-hole option for board assemblies and repair-friendly layouts.
• Clear electrical limits — Specified leakage current (102 µA) and ±20% capacitance tolerance offer concrete parameters for margin and tolerance calculations.
• RoHS compliant and production-ready — Meets RoHS requirements and is available in mass production with standard bulk or bag packing options.
