UPJ1K270MED

The UPJ1K270MED is an aluminum electrolytic, radial-lead capacitor designed for low-impedance power applications. It delivers 27 µF at 80 V with a polarized can package optimized for switching power supplies and general-purpose power filtering.

With a compact φ6.3 × 15 mm can, a wide operating temperature range of -55°C to 105°C and a rated endurance of 2000 hours at 105°C, this part targets through-hole designs that require reliable ripple handling and compact high-voltage decoupling.

Key Features

• Capacitance & Voltage — 27 µF rated capacitance at 80 V with ±20% tolerance (measured at 20°C, 120 Hz).
• Low-Impedance Performance — Specified for low impedance use in switching power supplies; tangent of loss angle (tanδ) is 0.08 (20°C, 120 Hz) at this voltage class.
• Ripple Current Handling — Low-frequency ripple current 40 mA (120 Hz) and high-frequency ripple current 80 mA (200 kHz) for effective smoothing under switching conditions.
• Leakage Current — Measured leakage current of 64.8 µA, supporting predictable DC bias behavior in power circuits.
• Thermal & Endurance — Rated for -55°C to 105°C operation with a life/endurance rating of 2000 hours at 105°C.
• Mechanical & Mounting — Radial lead can with 2.5 mm lead spacing (±0.5 mm tolerance) and compact size φ6.3 × 15 mm (L: 1.5 cm × D: 0.63 cm) for through-hole assemblies.
• Packaging & Compliance — Supplied in bulk / bag packing (no terminal forming) and RoHS-compliant.

Typical Applications

• Switching Power Supplies — Input/output smoothing and decoupling where low impedance and defined ripple handling are required.
• General-Purpose Power Filtering — Through-hole decoupling and bulk filtering in industrial and consumer power electronics.
• Through-Hole Power Rails — Radial-lead format suited for PCB designs that prefer or require through-hole components for power rail stability.

Unique Advantages

• Compact high-voltage solution: 80 V rating in a φ6.3 × 15 mm can provides high-voltage capability while minimizing board area.
• Designed for switching environments: Low tanδ and specified ripple currents (40 mA / 80 mA) help manage AC stress from switching supplies.
• Predictable lifetime at elevated temperature: Rated 2000 hours at 105°C for clear end-of-life planning in thermal designs.
• Through-hole assembly friendly: Radial leads with 2.5 mm spacing and bulk/bag packaging support straightforward manual or wave solder assembly processes.
• Regulatory compliance: RoHS-compliant construction supports use in RoHS-directed products and assemblies.
