UPM1A271MED

The UPM1A271MED from Nichicon is a radial-lead aluminum electrolytic capacitor offering 270 µF capacitance at a 10 V rating. Engineered as part of the UPM series, it provides low impedance and high reliability in a compact φ6.3 × 15 mm can package with 2.5 mm lead spacing.

Designed for demanding environments, this polarized capacitor delivers practical ripple-current handling and a wide operating temperature range of −55°C to 105°C, making it suitable for automotive and other temperature-stable applications that require robust decoupling and smoothing performance.

Key Features

• Capacitance & Voltage — 270 µF rated capacitance at 10 V with ±20% tolerance for predictable bulk energy storage and decoupling.
• Low Loss Characteristics — tan δ of 0.19 (at 120 Hz, 20°C) to help minimize dissipation in AC conditions.
• Ripple Current Capability — 171 mA at 120 Hz (low frequency) and 300 mA at 200 kHz (high frequency) for effective smoothing under dynamic loads.
• Leakage Current — 81 µA specified, supporting low standby losses in power rails.
• Thermal and Lifetime Performance — rated for operation from −55°C to 105°C with a specified life of 2000 hours at 105°C.
• Package and Mounting — radial, can-style package (φ6.3 × 15 mm) with 2.5 mm lead spacing and radial lead mounting for through-hole assemblies.
• Standards & Environmental — AEC-Q200 qualified and RoHS compliant, reflecting series-level reliability and regulatory compliance.
• Polarized Design — intended for applications that require polarized electrolytic capacitors.

Typical Applications

• Automotive Electronics — smoothing and decoupling on power rails in automotive modules, leveraging the −55°C to 105°C operating range and AEC‑Q200 qualification.
• Power Supply Filtering — bulk capacitance and ripple handling for DC/DC converters and linear regulators in embedded systems.
• Sensor and ECU Support — local energy storage and transient suppression where stable capacitance and low leakage are required across a wide temperature span.
• Infotainment and Control Modules — decoupling in supply networks where compact radial cans and reliable long-term performance are needed.

Unique Advantages

• Balanced ripple handling: Dual-specified ripple currents (171 mA @120 Hz, 300 mA @200 kHz) enable the capacitor to address both low- and high-frequency ripple in mixed-signal power designs.
• Thermal endurance: Rated for continuous operation to 105°C with a 2000-hour life rating at that temperature, supporting designs exposed to elevated operating temperatures.
• Compact, serviceable form factor: φ6.3 × 15 mm radial-can package with 2.5 mm lead spacing fits tight through-hole layouts while remaining easy to replace or prototype with.
• AEC‑Q200 qualification: Series-level automotive qualification provides an established reliability baseline for vehicle electronics projects.
• Low leakage and controlled loss: 81 µA leakage current and a tan δ of 0.19 contribute to efficient power management and predictable AC behavior.
• Regulatory compliance: RoHS compliant for use in environments requiring restricted-substance conformity.
