UPM1E181MPD

The UPM1E181MPD is a radial-lead aluminum electrolytic capacitor designed for demanding environments. It features a 180 µF capacitance at 25 V, polar construction, and a compact radial can package (φ8 × 15L) with 3.5 mm lead spacing.

Targeted at applications requiring high reliability and temperature endurance, this part combines low impedance, controlled loss (tan δ), and specified ripple and leakage characteristics for stable power and filtering performance across -55°C to +105°C.

Key Features

• Electrical Specification — 180 µF capacitance at 25 V with ±20% tolerance, suitable for bulk decoupling and energy storage where this capacitance and voltage are required.
• Low Impedance and Loss — Specified impedance of 140 mΩ and tan δ of 0.14 provide predictable AC performance for smoothing and ripple suppression.
• Ripple and Leakage — Rated ripple currents of 210.6 mA at 120 Hz and 390 mA at 200 kHz, with leakage current specified at 135 µA, enabling reliable operation under AC stress conditions.
• Temperature and Lifetime — Operating temperature range from -55°C to +105°C and a rated lifetime of 3000 hours at 105°C for the smaller case sizes, supporting high-temperature duty cycles.
• Package and Mounting — Radial lead (can) package, diameter φ8 × length 15 mm, with 3.5 mm lead spacing and 0.6 mm lead diameter, optimized for through-hole assemblies.
• Qualification and Compliance — AEC-Q200 rated and RoHS compliant, aligning with requirements for regulated and automotive-influenced applications.

Typical Applications

• Automotive electronics — AEC-Q200 qualification and 3000 h life at 105°C make the UPM1E181MPD suitable for automotive electronic modules that require temperature endurance and reliability.
• Power supply smoothing — Low impedance (140 mΩ) combined with specified ripple current ratings supports bulk filtering and smoothing in power rails exposed to AC ripple.
• High-temperature systems — Rated for -55°C to +105°C and specified endurance at 105°C, suitable for electronics operating in elevated-temperature environments.

Unique Advantages

• Engineered for thermal endurance — 3000 hours at 105°C specification ensures sustained performance in prolonged high-temperature conditions.
• Predictable AC behavior — Measured impedance (140 mΩ), tan δ (0.14), and ripple current specifications give designers quantifiable parameters for filter and decoupling design.
• Compact radial form factor — φ8 × 15 mm can and 3.5 mm lead spacing deliver a small footprint for through-hole assemblies without sacrificing capacitance.
• Low leakage — Specified leakage current of 135 µA supports circuits sensitive to standby current and long-term charge retention.
• Standards-aligned qualification — AEC-Q200 rating and RoHS compliance help meet regulatory and reliability requirements for regulated markets.
