UPM1H180MDD

The UPM1H180MDD is a miniature aluminum electrolytic capacitor in a radial-lead can designed for high-reliability applications. It delivers 18 µF capacitance at 50 V in a compact φ5×11 mm package with 2 mm lead spacing.

Built for demanding environments, this AEC-Q200-qualified, RoHS-compliant device offers low loss (tanδ 0.1 at 20°C, 120 Hz), specified ripple handling, and a wide operating temperature range of -55°C to 105°C—making it suitable for compact power filtering and decoupling in industrial and automotive electronics.

Key Features

• Electrical Performance — 18 µF nominal capacitance with ±20% tolerance and a rated voltage of 50 V, providing predictable filtering and energy storage for low-voltage power rails.
• Low Loss and Leakage — Dissipation factor (tanδ) of 0.1 at 20°C/120 Hz and typical leakage current of 27 µA, supporting stable performance in long-running circuits.
• Ripple Handling — Specified low-frequency ripple current of 39.5 mA at 120 Hz and high-frequency ripple current of 79 mA at 200 kHz for smoothing and decoupling in switching and linear supplies.
• Compact Radial Package — φ5×11 mm can with 2 mm lead spacing and standard radial leads for through-hole mounting in space-constrained designs.
• Wide Temperature Range — Rated for -55°C to 105°C to maintain capacitance and performance across harsh operating conditions.
• Reliability & Endurance — Specified life/endurance of 2000 hours at 105°C for this part; the UPM series also offers longer endurance options across other case sizes.
• Qualification & Compliance — AEC-Q200 rating and RoHS compliance for regulated environments and automotive-focused designs.
• Polarized — Designed as a polarized aluminum electrolytic capacitor for correct-polarity DC circuits.

Typical Applications

• Automotive Electronics — Local decoupling and smoothing in compact automotive modules and control units where AEC-Q200 qualification is required.
• Power Supply Filtering — Bulk and output filtering in compact DC–DC converters and linear regulators, leveraging the capacitor’s ripple current ratings.
• Industrial Controls — Energy storage and noise suppression in motor controllers, sensor modules, and embedded industrial electronics operating over a wide temperature range.
• Embedded Systems — Compact decoupling for microcontrollers, power management ICs, and small form-factor PCBs where board space is limited.

Unique Advantages

• Compact footprint: φ5×11 mm radial can and 2 mm lead spacing enable use in dense, space-constrained PCB layouts.
• Series-level reliability: Part of the UPM series, which is designed for low impedance and high reliability; this specific part is specified for 2000 hours at 105°C.
• Automotive-ready qualification: AEC-Q200 rating supports integration into automotive-grade designs that require qualified components.
• Measured performance data: Specified tanδ, leakage current, and ripple currents allow straightforward thermal and lifetime calculations during design.
• RoHS compliance: Conforms to RoHS requirements for use in regulated production environments.
