UPM1H121MPD

The UPM1H121MPD is a radial-lead aluminum electrolytic capacitor from Nichicon's UPM series, designed for low impedance and high reliability in demanding electronic power applications. It delivers 120 µF capacitance at a 50 V rating with a compact φ8 × 20 mm can and 3.5 mm lead spacing.

Targeted for systems that require robust ripple handling and extended high-temperature endurance, this part is AEC-Q200 qualified, RoHS compliant, and produced for mass-volume supply.

Key Features

• Capacitance & Voltage: 120 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance at 120 Hz, 20°C for predictable decoupling and smoothing.
• Low Impedance: Rated impedance of 120 mΩ supports efficient energy transfer and reduced voltage ripple in power circuits.
• Ripple Current Capability: Low-frequency ripple current 270.3 mA (120 Hz) and high-frequency ripple current 510 mA (200 kHz) for broad-spectrum ripple handling.
• Loss & Leakage: Dissipation factor tanδ of 0.1 (20°C, 120 Hz) and leakage current specified at 180 µA for controlled losses and standby current.
• High-Temperature Endurance: Rated for 3,000 hours at +105°C, providing durability under elevated operating temperatures.
• Automotive-Grade Qualification: AEC-Q200 qualification and an operating temperature range of −55°C to +105°C for automotive and harsh-environment electronics.
• Radial Lead Package: φ8 × 20 mm can with 3.5 mm lead spacing (±0.5 mm) and bulk/bag packing (no terminal forming) for straightforward through-hole assembly.
• Environmentally Compliant: RoHS compliant construction suitable for regulatory-conscious designs.

Typical Applications

• Automotive power modules: AEC-Q200 qualification, 50 V rating and high ripple capability make it suitable for power smoothing and decoupling in vehicle electronic control units.
• DC‑DC converters and power supplies: 120 µF capacitance and low impedance help stabilize output rails and reduce voltage ripple across switching frequencies.
• Infotainment and body electronics: Compact φ8 × 20 mm package and robust temperature endurance support decoupling in compact, elevated-temperature modules.
• Industrial control electronics: High ripple current capability and long life at 105°C suit ruggedized power circuits and sensor interface conditioning.

Unique Advantages

• Balanced performance and size: 120 µF in a φ8 × 20 mm can provides meaningful capacitance without a large board footprint.
• High ripple resilience: Dual-specified ripple currents (120 Hz and 200 kHz) enable reliable performance across both low- and high-frequency power noise sources.
• Elevated-temperature longevity: 3,000-hour endurance at +105°C addresses lifetime requirements for thermally-stressed designs.
• Automotive-capable construction: AEC-Q200 qualification supports use in automotive electronics where supplier qualification is required.
• Predictable electrical behavior: Low impedance (120 mΩ) and defined tanδ and leakage values allow tight design margins in power filtering networks.
• Production-ready packaging: Supplied in bulk/bag packing without terminal forming to match high-volume assembly flows.
