UPJ0J271MED

The UPJ0J271MED is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon's UPJ series. It is a radial-lead, polarized can capacitor specified at 270 µF and 6.3 V, designed for general-purpose electronic filtering and power supply applications.

Key performance characteristics include a low loss tangent (tanδ = 0.22 at 20°C, 120 Hz), defined ripple-current ratings for low- and high-frequency operation, and an operating temperature range from −55°C to 105°C. Status: End Of Life.

Key Features

• Capacitance & Tolerance — 270 µF nominal with ±20% tolerance, suitable for smoothing and bulk energy storage in compact circuits.
• Rated Voltage & Polarization — Rated at 6.3 V and polarized for DC applications.
• Loss Characteristics — Tangent of loss angle (tanδ) of 0.22 measured at 20°C, 120 Hz, providing predictable loss behavior for design calculations.
• Ripple Current Handling — Low-frequency ripple current: 156.8 mA at 120 Hz; high-frequency ripple current: 275 mA at 200 kHz, enabling use across a range of switching and linear power conditions.
• Leakage Current — Specified leakage current of 51.03 µA for predictable standby and bias behavior.
• Reliability & Lifetime — Endurance specified at 2000 hours at 105°C, supporting sustained operation in elevated-temperature environments.
• Temperature Range — Rated for −55°C to +105°C to cover a wide span of operating conditions.
• Compact Radial Package — Can dimensions φ6.3 × 15 mm (L) with 2.5 mm lead spacing (±0.5 mm), radial-lead mounting for through-hole assemblies; supplied bulk or in bag packing.
• RoHS Compliant — Meets RoHS requirements for restricted substances.

Typical Applications

• Switching Power Supplies — Low-impedance UPJ series construction and defined ripple ratings make this part suitable for input/output filtering in switching regulators.
• General Purpose Filtering — Bulk smoothing and decoupling in consumer and industrial electronics where a compact radial electrolytic is required.
• Power Rail Stabilization — Provides local energy storage and transient suppression for DC power rails at low voltage.

Unique Advantages

• Defined electrical behavior: Specified capacitance, tanδ, leakage, and ripple-current values give engineers predictable performance for margin and thermal calculations.
• Compact radial form factor: φ6.3 × 15 mm can with 2.5 mm lead spacing enables high-density through-hole layouts while maintaining robust mounting.
• Wide operating temperature: −55°C to +105°C rating supports deployment across a broad range of environments.
• Quantified endurance: 2000 hours at 105°C provides a clear reliability metric for lifetime planning.
• RoHS compliance: Facilitates integration into products that require restricted-substance conformity.
