UPM1H2R2MDD

The UPM1H2R2MDD is a miniature, high-reliability aluminum electrolytic capacitor from Nichicon’s UPM series. It is a polarized, radial-lead can designed for compact power-filtering and decoupling roles in equipment that requires wide temperature tolerance and long endurance.

Key attributes include a 2.2 µF capacitance at 50 V, low dissipation factor, low leakage, and AEC-Q200 qualification, making it suitable for demanding applications that operate between -55°C and 105°C.

Key Features

• Compact radial-can package — Small form factor: φ5 × 11 mm can with 2.0 mm lead spacing and 0.5 mm lead-spacing tolerance for tight PCB layouts.
• Electrical characteristics — 2.2 µF capacitance with tolerance −20% to +20%, rated for 50 V, and polarized construction for DC filtering and decoupling.
• Low loss and low leakage — Dissipation factor (tan δ) 0.10 measured at 20°C, 120 Hz, and leakage current specified at 4 µA for stable performance in bias applications.
• Ripple performance — Low-frequency ripple current 13.5 mA at 120 Hz and high-frequency ripple current 27 mA at 200 kHz for both mains-frequency and switching-power noise suppression.
• High-temperature endurance — Rated for operation from −55°C to +105°C with a specified life/endurance of 2000 hours at 105°C.
• Automotive-capable qualification — AEC-Q200 rated for designs that require recognized component-level automotive qualification.
• Regulatory compliance and packaging — RoHS compliant; available in bulk (no terminal forming) and bag packing to support production and prototyping workflows.

Typical Applications

• Automotive electronics — Local decoupling and filtering in control modules and sensor interfaces where AEC-Q200 qualification and elevated-temperature endurance are required.
• Power-supply filtering — Input/output smoothing and ripple suppression for compact DC–DC converters and linear regulators in space-constrained designs.
• Embedded systems — Bypass and timing-capacitance roles on compact PCBs where low leakage and low dissipation factor improve stability.
• Signal conditioning — Noise suppression in analog front ends and mixed-signal boards that benefit from low tan δ and predictable leakage.

Unique Advantages

• Small footprint for constrained PCBs: φ5 × 11 mm can and 2.0 mm lead spacing enable placement in compact assemblies without sacrificing performance.
• Reliable high-temperature operation: 2000-hour endurance at 105°C supports long-term performance in elevated-temperature environments.
• Low loss and low leakage: tan δ of 0.10 and 4 µA leakage current minimize power dissipation and DC bias error in sensitive circuits.
• Broad ripple handling: Specified ripple currents at 120 Hz and 200 kHz provide measurable performance across both low- and high-frequency noise sources.
• Automotive-level qualification: AEC-Q200 rating supports use in designs targeting automotive and similarly demanding markets.
• RoHS-compliant packaging options: Bulk and bag packing accommodate both prototype quantities and production needs while meeting RoHS requirements.
