UPJ1H270MED

The UPJ1H270MED is an aluminum electrolytic capacitor from Nichicon's UPJ series, presented in a radial-can package for through-hole mounting. It provides a 27 µF capacitance at a 50 V rating with polarized radial leads and is targeted for general-purpose power applications.

As a member of the UPJ series, this part is designed for low-impedance performance useful in switching power supplies and power-filtering circuits, while offering a wide operating temperature range and measurable ripple-current capability across low and high frequencies.

Key Features

• Capacitance & Voltage: 27 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance for standard power supply bulk and decoupling needs.
• Low-loss Characteristics: Rated tan δ of 0.10 at 50 V, supporting lower dissipation and stable AC behavior in power applications.
• Leakage Current: Specified leakage current of 510.3 µA, enabling predictable standby and leakage performance after voltage application.
• Thermal and Reliability: Operating temperature range from −55 °C to +105 °C with a specified lifetime of 2000 hours at 105 °C for durability under elevated temperature stress.
• Ripple Current Ratings: 57.5 mA at 120 Hz and 115 mA at 200 kHz, useful for evaluating performance under different switching and ripple conditions.
• Package & Mounting: Radial lead can with 2.5 mm lead spacing and dimensions L: 1.1 × D: 0.63 cm for compact through-hole layouts; polarized for correct orientation in circuits.
• Regulatory Compliance: RoHS compliant, aligning with common environmental requirements.

Typical Applications

• Switching Power Supplies: Low-impedance UPJ series design supports bulk and output filtering in switching regulators and converters.
• Power Rail Decoupling: Suitable for local decoupling on 50 V rails where a compact radial electrolytic is required.
• General-Purpose Electronics: Useful across consumer and industrial general-purpose power circuits that require a polarized aluminum electrolytic.

Unique Advantages

• Low-impedance series heritage: Part of the UPJ family, designed with series-level low-impedance characteristics that help reduce ripple and improve voltage stability in switching environments.
• Measurable ripple performance: Published ripple current values at both low (120 Hz) and high (200 kHz) frequencies let engineers size capacitors to expected operating conditions.
• Wide temperature range: −55 °C to +105 °C operating range supports deployment across a broad set of environments.
• Compact radial can: Small footprint (L: 1.1 × D: 0.63 cm) and 2.5 mm lead spacing simplify placement in tight through-hole designs.
• Predictable leakage behavior: Specified leakage current figure provides a clear baseline for power-budget and standby-current calculations.
• RoHS compliant: Meets common environmental directives for use in regulated assemblies.
