UPM1E390MDD

The UPM1E390MDD is a miniature aluminum electrolytic capacitor in a radial-lead can from Nichicon’s UPM series. It provides 39 µF capacitance at a 25 V rating in a compact φ5 × 11 mm package with 2 mm lead spacing.

Designed as a high-reliability component within the UPM family, this part is targeted at compact electronics and automotive-grade designs where stable capacitance, wide operating temperature range, and measurable ripple handling are required.

Key Features

• Capacitance and Voltage: 39 µF rated at 25 V for decoupling and energy storage in compact circuits.
• Radial Lead Package: φ5 × 11 mm can with 2 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly.
• High Reliability UPM Series: Part of Nichicon’s UPM family, noted for low impedance and high reliability characteristics.
• Temperature Range: Operates from −55°C to +105°C, supporting demanding thermal environments.
• Endurance: Rated for 2000 hours at 105°C under specified conditions for long-term stability in harsh environments.
• Tolerance and Dissipation Factor: Capacitance tolerance −20% to +20% with tanδ (DF) 0.14 measured at 20°C, 120 Hz for predictable AC performance.
• Ripple Handling: Low-frequency ripple current 51 mA at 120 Hz and high-frequency ripple current 100 mA at 200 kHz, specified for application-level ripple considerations.
• Leakage Current: Specified leakage current 29.25 µA, measurable for power-budget planning and bias considerations.
• AEC‑Q200 Rating and RoHS Compliance: AEC‑Q200 listed rating and RoHS compliance for use in regulated environments and automotive component stacks.

Typical Applications

• Automotive electronics: Suited for automotive control modules and electronic assemblies that require an AEC‑Q200‑listed, compact electrolytic capacitor.
• Compact power modules: Used for output smoothing and bulk decoupling in space‑constrained DC/DC converters and power-supply circuits.
• Embedded control boards: Fits small PCBs where a reliable through-hole electrolytic capacitor is needed for transient handling and energy storage.

Unique Advantages

• Compact form factor: φ5 × 11 mm can and 2 mm lead spacing enable high-density board layouts and compact designs.
• Measurable ripple specifications: Explicit low‑ and high‑frequency ripple current ratings (51 mA @120 Hz, 100 mA @200 kHz) allow accurate thermal and ripple budgeting.
• Wide operating temperature: −55°C to +105°C rating supports designs that must operate across large temperature ranges.
• Automotive-capable qualification: AEC‑Q200 listing provides a documented supplier-level qualification path for automotive electronics projects.
• predictable electrical characteristics: Specified tanδ and leakage current figures (0.14 tanδ; 29.25 µA leakage) help ensure predictable behavior in AC and dc-biased circuits.
• RoHS compliant: Meets RoHS directive requirements for regulated manufacturing environments.
