UPJ1E101MED

The UPJ1E101MED is a radial-lead aluminum electrolytic capacitor from Nichicon's UPJ series, configured for general-purpose power applications. This miniature, polarized can delivers 100 µF at 25 V in a compact φ6.3 × 15 mm package with 2.5 mm lead spacing.

Designed around the UPJ series architecture — which targets low impedance and high reliability for switching power supplies — this part provides a combination of ripple-handling capability, wide operating temperature range (−55°C to +105°C) and RoHS compliance for board-level power decoupling and filtering.

Key Features

• Capacitance & Voltage — 100 µF nominal capacitance at a rated voltage of 25 V with tolerance ±20% (measured at 120 Hz, 20°C).
• Low Loss Characteristic — tanδ (DF) 0.14 at 20°C, 120 Hz, delivering controlled dissipation for power supply decoupling.
• Ripple Current Capability — Low-frequency ripple current 127.4 mA at 120 Hz and high-frequency ripple current 245 mA at 200 kHz to support switching regulator requirements.
• Leakage and Endurance — Leakage current 75 µA and specified life/endurance of 2000 hours at rated conditions and 105°C for this part.
• Mechanical & Mounting — Radial lead, polarized can with φ6.3 × 15 mm dimensions, 2.5 mm lead spacing (±0.5 mm tolerance) for through-hole PCB mounting.
• Temperature Range & Compliance — Operates from −55°C to +105°C; RoHS compliant.
• Packaging — Supplied as Bulk (No Terminal Forming) or Bag Packing for straightforward factory handling.

Typical Applications

• Switching Power Supplies — Bulk decoupling and output smoothing where the UPJ series' low-impedance characteristics aid voltage stability.
• Embedded Power Modules — Local energy storage and ripple attenuation in compact, through-hole power modules and boards.
• General Purpose Electronics — Filtering and decoupling in control boards, industrial electronics and consumer equipment that require a compact 25 V electrolytic solution.

Unique Advantages

• Compact, PCB-friendly package: φ6.3 × 15 mm radial can with 2.5 mm lead spacing simplifies placement in tight through-hole layouts.
• Designed for switching environments: Series-level low-impedance characteristics and measured ripple current specs support switching regulator performance.
• Wide operating temperature: −55°C to +105°C rating provides design margin across a broad range of operating conditions.
• Clear endurance specification: Part-specific 2000 h life at 105°C gives predictable long-term behavior for thermal-stressed designs.
• Regulatory compliance: RoHS compliance supports use in regulated product lines and simplifies environmental qualification.
• Simple procurement and handling: Bulk and bag packing options accommodate prototype and production workflows.
