UPJ1K100MED

The UPJ1K100MED is a radial-leaded aluminum electrolytic capacitor from Nichicon's UPJ series, designed for low-impedance power applications. It offers a 100µF capacitance at an 80V rating in a compact φ6.3×11mm can and is targeted for general-purpose power filtering and switching power supply use.

Key product attributes include a wide operating temperature range of -55°C to 105°C, defined ripple-current ratings for low and high frequencies, low leakage current, and RoHS compliance. Note: the part status is End Of Life.

Key Features

• Capacitance & Rated Voltage — 100µF rated capacitance with an 80V maximum operating voltage, suitable for higher-voltage power rail decoupling and filtering.
• Low-impedance UPJ Series Design — Part of Nichicon's UPJ series, characterized for low impedance performance useful in switching power supplies.
• Temperature and Endurance — Rated for -55°C to 105°C with a specified life/endurance of 2000 hours at 105°C.
• Loss Characteristics — Specified tanδ of 0.08 (measured at 20°C, 120Hz) for predictable dissipation behavior.
• Ripple Current Ratings — Low-frequency ripple current of 21.5 mA (120Hz) and high-frequency ripple current of 43 mA (200 kHz) for mixed-frequency power environments.
• Leakage Current — Low leakage current specified at 24 µA for stable bias performance after application of rated voltage.
• Compact Radial Package — φ6.3×11 mm can with 2.5 mm lead spacing (±0.5 mm) and polarized radial-lead mounting for through-hole assemblies.
• Packaging Options — Supplied in bulk (no terminal forming) or bag packing to suit assembly or prototyping workflows.
• RoHS Compliant — Conforms to RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Low-impedance characteristics and 80V rating make it suitable for output filtering and smoothing in switching regulators.
• DC-DC Converters — Compact radial package and defined ripple ratings support decoupling on higher-voltage converter stages.
• General Power Filtering — Useful for bulk smoothing and decoupling in industrial and consumer power modules where through-hole components are preferred.

Unique Advantages

• High Voltage Capability: 80V rating enables use on higher-voltage rails without paralleling multiple lower-voltage capacitors.
• Predictable Performance: Specified tanδ, leakage current, and ripple-current values provide clear parameters for thermal and ripple budgeting in designs.
• Compact Footprint: φ6.3×11mm can and 2.5mm lead spacing deliver a small through-hole solution for dense assemblies.
• Wide Temperature Range: -55°C to 105°C rating supports operation across harsh thermal environments common in industrial electronics.
• Supply Flexibility: Available in bulk or bag packing to accommodate prototype builds and production runs.
• Regulatory Compliance: RoHS compliance simplifies integration into products targeting regulated markets.

Why Choose UPJ1K100MED?
