UPM1V181MPD

The UPM1V181MPD is a radial aluminum electrolytic capacitor from Nichicon’s UPM series, offering 180 µF capacitance at a 35 V rating in a compact φ8 × 20 mm can. Designed for demanding environments, it combines low impedance, measurable ripple handling and AEC-Q200 qualification for automotive applications.

This polarized radial-lead device is intended for power-filtering and DC-rail smoothing roles where temperature tolerance, ripple capability and long operating life are required.

Key Features

• Electrical Performance — 180 µF nominal capacitance at 35 V with ±20% tolerance, providing bulk energy storage for power rails and decoupling.
• Low Impedance — Specified impedance of 100 mΩ, supporting efficient high-frequency and transient current demands.
• Ripple Handling — Rated ripple current of 280.8 mA at 120 Hz and 520 mA at 200 kHz, suitable for filtering and smoothing in switching power environments.
• Loss Characteristics — Tangent of loss angle (tan δ) of 0.12 at the 35 V rating (measured at 120 Hz, 20°C).
• Reliability & Life — Load life of 3000 hours at 105°C for the specified case size, with leakage current specified at 189 µA.
• Temperature Range — Operating range from −55°C to +105°C to support wide environmental variation.
• Mechanical & Mounting — Radial lead can package, φ8 × 20 mm body, 3.5 mm lead spacing, suitable for through-hole, radial-lead assemblies; polarized construction.
• Compliance & Qualification — RoHS compliant and AEC-Q200 rated, aligning with automotive component qualification requirements.
• Packaging — Supplied in bulk packaging for high-volume assembly and manual or automated through-hole processes.

Typical Applications

• Automotive power filtering — Used on vehicle DC rails for smoothing and ripple reduction, leveraging its ripple-current ratings and wide operating temperature range.
• DC/DC converter output smoothing — Provides bulk capacitance and low impedance to stabilize outputs in switching power supplies.
• Electronic control modules — Fits compact board layouts where a polarized radial capacitor with AEC-Q200 qualification and long life is required.
• Backup and hold-up circuits — Supplies transient energy storage for short-term power needs thanks to its 180 µF capacitance and low leakage characteristics.

Unique Advantages

• High ripple endurance: Explicit ripple current ratings at 120 Hz and 200 kHz enable designers to size capacitors against real switching and low-frequency ripple stresses.
• Wide ambient tolerance: Rated for −55°C to +105°C operation, supporting both cold-start and high-heat environments common in automotive applications.
• Long high-temperature life: 3000 hours at 105°C provides predictable aging characteristics for designs targeting extended field life.
• Measurable low impedance: 100 mΩ impedance supports lower voltage ripple and improved transient response on power rails.
• Qualification and compliance: AEC-Q200 rating and RoHS compliance reduce qualification overhead for automotive subsystems.
• Compact radial format: φ8 × 20 mm can with 3.5 mm lead spacing delivers a small footprint for through-hole layouts while maintaining required capacitance.
