UPJ2A101MPD

The UPJ2A101MPD is a polarized aluminum electrolytic capacitor in Nichicon’s UPJ series, offering a 100 µF capacitance at a 100 V rating in a radial-lead can. It combines low impedance characteristics from the UPJ family with a compact φ10 × 30.5 mm can size and radial mounting for general-purpose power applications.

Designed for applications that require robust ripple handling and long-term thermal endurance, this part is well suited to switching power supplies and other general-purpose electronic power circuitry where a high-voltage electrolytic capacitor is required.

Key Features

• Rated Capacitance & Voltage — 100 µF capacitance at a 100 V rated voltage for mid-to-high voltage power rail support.
• Low Impedance Design — Part of the UPJ series noted for low impedance construction, making it appropriate for switching power supply use.
• High Temperature Endurance — Load-life endurance of 5000 hours at +105°C for sustained performance in elevated ambient temperatures.
• Ripple Current Performance — Low-frequency ripple current 227.8 mA (120 Hz) and high-frequency ripple current 438 mA (200 kHz) to support practical power-filtering requirements.
• Dielectric Loss and Leakage — Specified tan δ of 0.08 (measured at 20°C, 120 Hz) and leakage current of 300 µA, enabling predictable loss and leakage behavior in designs.
• Radial Lead Package — Radial lead mounting, φ10 × 30.5 mm size with 5 mm lead spacing (±0.5 mm tolerance), suited for through-hole PCB placement and prototyping.
• Regulatory & Packaging — RoHS compliant and available in bulk (no terminal forming) / bag packing for production and assembly flexibility.

Typical Applications

• Switching Power Supplies — Low-impedance behavior and specified ripple current levels support output smoothing and energy buffering in switching regulators.
• General-Purpose Power Filtering — Suitable for decoupling and bulk energy storage in a wide range of electronic equipment classified as general purpose.
• Industrial Power Modules — Endurance at +105°C and radial lead packaging make it a practical choice for industrial power assemblies requiring reliable electrolytic capacitance.

Unique Advantages

• Long Thermal Load Life: 5000 hours at +105°C provides predictable lifetime behavior under sustained thermal stress.
