UPJ1C151MED

The UPJ1C151MED is a radial-lead aluminum electrolytic capacitor in the Nichicon UPJ series. It delivers 150 µF at a 16 V rating with a radial can package intended for general-purpose electronic applications and switching power supplies.

Key electrical characteristics include a capacitance tolerance of ±20% (120 Hz, 20°C), a tanδ (DF) of 0.16 (measured at 20°C, 120 Hz), specified ripple current values at both low and high frequency, a leakage current of 72 µA, and rated operation from -55°C to 105°C with a 2000-hour endurance at 105°C. The part is supplied in bulk or bag packing and is RoHS compliant.

Key Features

• Capacitance & Rated Voltage — 150 µF nominal capacitance at 16 V with ±20% tolerance measured at 120 Hz, 20°C.
• Low-loss Performance — tanδ (DF) 0.16 at 20°C, 120 Hz for predictable AC characteristics in filter and decoupling roles.
• Ripple Current Specified — Low-frequency ripple current 140.4 mA (120 Hz) and high-frequency ripple current 260 mA (200 kHz) to support both mains- and switching-frequency applications.
• Leakage Current — Rated leakage current of 72 µA to aid in predictable standby and bias behavior.
• Temperature & Endurance — Operating range from -55°C to 105°C with an endurance rating of 2000 hours at 105°C.
• Radial Lead Package — Compact radial can sized φ6.3 × 15 mm with 2.5 mm lead spacing (±0.5 mm) for through-hole PCB assemblies; available in bulk (no terminal forming) or bag packing.
• Regulatory — RoHS compliant.

Typical Applications

• Switching Power Supplies — Suited for use in switching power supplies where low-impedance capacitors are required for filtering and energy buffering.
• General-Purpose Electronics — Applicable to general-purpose boards and circuits requiring radial electrolytic capacitance for decoupling and smoothing.
• Radial-Lead PCB Assemblies — Designed for through-hole assemblies that need a compact, axial-stable radial can with defined lead spacing.

Unique Advantages

• Measured AC loss specification — tanδ 0.16 at standard test conditions provides a quantifiable indicator of AC loss for design validation.
• Dual-frequency ripple ratings — Explicit ripple current values at both 120 Hz and 200 kHz let you size capacitors for mains and switching frequencies without extrapolation.
• High-temperature endurance — 2000 hours at 105°C supports designs that operate in elevated ambient or high-stress power environments.
• Compact radial can — φ6.3 × 15 mm body and 2.5 mm lead spacing make the part suitable for space-constrained through-hole layouts.
• Predictable leakage behavior — Specified leakage current (72 µA) aids bias and standby current budgeting in power designs.
• RoHS compliance — Meets RoHS requirements for applications requiring lead-free material compliance.
