UPM2A271MHD6

The UPM2A271MHD6 from Nichicon is a radial-lead aluminum electrolytic capacitor in the UPM series, rated 270 µF at 100 V. Designed for applications that demand low impedance and long-term reliability, it targets automotive and other high-reliability power systems.

Key attributes include a compact φ18×20 mm can, AEC-Q200 qualification, RoHS compliance, and extended endurance under high temperature—supporting designs that require stable capacitance, controlled loss (tan δ), and defined ripple-handling capability.

Key Features

• Capacitance & Voltage — 270 µF nominal capacitance with a 100 V rated voltage and ±20% tolerance, suitable where higher voltage bulk capacitance is required.
• Low Impedance — Specified impedance of 80 mΩ supports lower ESR behavior for stable power delivery and reduced ripple voltage in power rails.
• High Reliability / Endurance — Rated for 5000 hours at +105 °C under specified load life conditions (per UPM series endurance data), enabling long-term performance in elevated-temperature environments.
• Ripple Current Capability — Low-frequency ripple current of 615.6 mA at 120 Hz and high-frequency ripple current of 1.08 A at 200 kHz to support smoothing and decoupling in power-supply circuits.
• Leakage & Loss Angle — Measured leakage current of 810 µA and tan δ of 0.08 (measured at 20 °C, 120 Hz) for predictable dissipation and standby characteristics.
• Robust Temperature Range — Operating range from −55 °C to +105 °C to accommodate automotive-grade thermal environments.
• Package & Mounting — Radial-lead can, size φ18×20 mm with 7.5 mm lead spacing (±0.5 mm), provided in bulk or bag packing; polarized construction.
• Standards & Compliance — AEC-Q200 qualified and RoHS compliant as specified for the UPM series and part data.

Typical Applications

• Automotive power systems — High-voltage (100 V) bulk capacitance and AEC-Q200 qualification support filtering and energy storage in automotive electronic modules operating up to +105 °C.
• Power-supply filtering — Low impedance and defined ripple-current ratings help reduce ripple voltage and stabilize DC rails in power converters and regulators.
• High-temperature environments — Wide operating range (−55 °C to +105 °C) and 5000‑hour endurance at 105 °C for applications that require sustained performance under elevated temperatures.

Unique Advantages

• Voltage headroom for demanding designs — 100 V rating provides margin for higher-voltage circuits requiring bulk capacitance.
• Predictable thermal endurance — Specified 5000‑hour load life at +105 °C gives clear expectations for long-term reliability in hot environments.
• Measured low-loss characteristics — tan δ of 0.08 (20 °C, 120 Hz) and 80 mΩ impedance support efficient energy handling with lower heat generation.
• Defined ripple performance — Listed ripple-current ratings at both low and high frequency enable engineers to size capacitors to meet ripple and lifetime trade-offs.
• Automotive-grade qualification — AEC-Q200 qualification matches the part to automotive electronic requirements where that standard is specified.
• RoHS compliance — Conforms to RoHS directive for materials compliance in regulated markets.
