UPM1K221MHD

The UPM1K221MHD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 220 µF capacitance at an 80 V rating. Engineered for low impedance and long-term reliability, it targets power-electronics and automotive applications that require stable bulk capacitance, ripple handling and elevated-temperature endurance.

Key attributes include a compact φ12.5×30.5 mm can, a 5 mm lead spacing, AEC‑Q200 qualification, a rated lifetime of 5000 hours at 105 °C, and RoHS compliance—making it suitable for designs that demand ruggedness and predictable long-term performance.

Key Features

• Capacitance & Voltage: 220 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance (120 Hz, 20 °C) for bulk energy storage and decoupling in medium-voltage circuits.
• Low loss / Low impedance: Rated impedance of 120 mΩ and a tangent of loss angle (tan δ) of 0.08 support efficient ripple dissipation and reduced AC loss.
• Leakage & Stability: Specified leakage current of 528 µA and defined tan δ limits provide predictable electrical behavior after voltage application.
• Ripple Current Capability: Rated ripple current of 473.2 mA at 120 Hz and 845 mA at 200 kHz for handling AC ripple across a range of switching and line-frequency conditions.
• High-temperature Endurance: 5000 hours load life at 105 °C (as specified) demonstrating extended reliability under elevated operating temperatures.
• Form Factor & Mounting: Radial-lead, can-style package (φ12.5×30.5 mm) with 5 mm lead spacing and bulk/bag packing options for through-hole assembly and flexible handling.
• Automotive-grade Qualification: AEC‑Q200 rating supports use in automotive electronic modules where qualified components are required.
• Wide Operating Range & Compliance: Operating temperature range of −55 °C to +105 °C and RoHS compliance for regulatory alignment.

Typical Applications

• Automotive Power Electronics: Bulk energy storage and smoothing in electronic control units and power modules, benefiting from AEC‑Q200 qualification and 5000 h life at 105 °C.
• DC‑DC Converters & Power Supplies: Input/output filtering and ripple reduction where 220 µF at 80 V and low impedance help stabilize intermediate rails.
• Motor Drive Systems: Smoothing and decoupling in inverter and drive circuits that require high ripple handling and elevated-temperature endurance.
• Industrial Control Electronics: Energy buffering and transient suppression in control modules operating across −55 °C to +105 °C environments.

Unique Advantages

• Proven long-term endurance: 5000 hours at 105 °C supports designs requiring extended high-temperature reliability.
• Automotive-capable qualification: AEC‑Q200 rating enables specification in automotive-grade systems and modules.
• Predictable ripple performance: Specified ripple currents at 120 Hz and 200 kHz combined with low impedance reduce thermal stress and improve system stability.
• Compact, serviceable package: Radial-lead can (φ12.5×30.5 mm) with 5 mm lead spacing simplifies through-hole mounting and replacement in serviceable designs.
• Regulatory readiness: RoHS compliance supports environmentally regulated programs and procurement requirements.
• Manufacturer backing: Part of Nichicon’s UPM series with mass-production status for consistent supply and long-term sourcing.
