The UPJ1K101MPD is a miniature, high-reliability aluminum electrolytic capacitor in Nichicon’s UPJ series. It is a radial-lead, polarized can-type capacitor specified at 100 µF and 80 V, designed for compact power-electronic assemblies.

Engineered for low impedance and extended endurance, this part is suited for switching power supplies and general-purpose power filtering where long life, high voltage capability, and compact size are required.

Key Features

• Electrical Specification: 100 µF capacitance with ±20% tolerance at 20°C, rated voltage 80 V, and polarization for DC applications.
• Low Loss (tan δ): Dissipation factor (tan δ) 0.08 measured at 20°C and 120 Hz for the 80 V rating, supporting efficient filtering and stable performance.
• Ripple Current Capability: Low-frequency ripple current 180.44 mA at 120 Hz and high-frequency ripple current 347 mA at 200 kHz, enabling use in switching and high-frequency converter circuits.
• Leakage Current: Specified leakage current 240 µA, measured per the product conditions, for predictable standby and charged-state behavior.
• High Endurance: Rated for 5000 hours life at +105°C under load, providing long-term reliability in elevated-temperature environments.
• Thermal Range: Operating temperature range −55°C to +105°C for broad environmental compatibility.
• Package & Mounting: Radial lead can, size φ10 × 25 mm with 5 mm lead spacing (±0.5 mm). Available in Bulk (no terminal forming) / Bag packing.
• Regulatory: RoHS compliant.

Typical Applications

• Switching Power Supplies: Low impedance and specified ripple current make it suitable for output filtering and bulk decoupling in switching regulators.
• DC–DC Converters: Compact 80 V rating and high ripple capability support energy storage and smoothing in converter modules.
• Industrial Power Equipment: Long 5000-hour endurance at 105°C and wide operating temperature range suit sustained operation in industrial power systems and control electronics.
• General Purpose Power Filtering: Polarized radial-lead format and predictable leakage/tan δ behavior make it a practical choice for general-purpose filtering and energy-storage tasks in electronic designs.

Unique Advantages

• Low Impedance Performance: Designed for low impedance behavior to improve filtering effectiveness in switching and high-frequency power applications.
• Long-Term Reliability: Endurance rated 5000 hours at +105°C delivers measurable longevity for high-temperature operating conditions.
• High Voltage Capability in a Small Footprint: 80 V rating in a compact φ10 × 25 mm radial can provides high-voltage performance where board space is constrained.
• Clear Electrical Characterization: Specified tan δ, leakage current, and ripple current values allow predictable electrical design and thermal budgeting.
• RoHS Compliant: Meets RoHS requirements for use in restricted-substance environments.
• Practical Packaging Options: Available in Bulk (no terminal forming) and Bag packing to support both prototyping and production handling.
