UPJ1A271MED

The UPJ1A271MED is a radial-lead aluminum electrolytic capacitor (270 µF, 10 V) from Nichicon's UPJ series, engineered for low impedance performance and compact board-level power filtering. It is a polarized, through-hole component in a φ6.3 × 15 mm can with 2.5 mm lead spacing.

Designed for general-purpose power applications and explicitly characterized for switching power supplies, the part delivers measurable ripple-handling capability, a wide operating temperature range from −55°C to +105°C, and a specified endurance rating for elevated-temperature operation.

Key Features

• Electrical Capacity — 270 µF capacitance at a rated voltage of 10 V with ±20% tolerance, suitable for board-level decoupling and bulk energy storage in low-voltage power rails.
• Low Loss / Dissipation — tanδ (DF) of 0.19 measured at 20°C, 120 Hz, 10 V, enabling predictable AC performance for filtering and smoothing tasks.
• Ripple Current Handling — Rated low-frequency ripple current of 171 mA (120 Hz) and high-frequency ripple current of 300 mA (200 kHz), useful where both line-frequency and switching-frequency ripple must be managed.
• Leakage and Reliability — Specified leakage current of 81 µA and an endurance rating of 2000 hours at 105°C, providing defined behavior under elevated-temperature stress.
• Thermal and Environmental Range — Operating temperature range from −55°C to +105°C and RoHS compliance for environmental regulatory alignment.
• Package and Mounting — Radial lead, polarized can (φ6.3 × 15 mm) with 2.5 mm lead spacing; supplied in bulk or bag packing for manual or wave-through-hole assembly workflows.

Typical Applications

• Switching Power Supplies — Low impedance characteristics and defined ripple ratings make it suitable for output filtering and smoothing in switching regulators.
• Board-Level Power Decoupling — Used on low-voltage power rails to stabilize supply transients and reduce ripple on PCBs.
• Consumer and Industrial Power Modules — Compact can size and wide temperature range suit small power modules and control electronics requiring reliable bulk capacitance.
• General Purpose Electronic Equipment — Polarized radial format and standard lead spacing allow straightforward integration into through-hole designs for general-purpose power conditioning.

Unique Advantages

• Compact, high-capacitance footprint — 270 µF in a φ6.3 × 15 mm can provides significant capacitance in a small through-hole package for space-constrained designs.
• Measured ripple capability — Specified ripple current values at both low and high frequencies let designers size capacitors against real-world AC stress from mains and switching sources.
• Defined high-temperature endurance — 2000 hours at 105°C gives a predictable reliability baseline for elevated-temperature applications.
• Wide operating temperature span — −55°C to +105°C operation supports designs exposed to broad ambient conditions.
• RoHS compliant — Meets RoHS requirements for environmental regulatory compliance in modern assemblies.
• Through-hole mounting convenience — Radial lead format and standard 2.5 mm lead spacing simplify placement and soldering in traditional PCB assembly workflows.
