UPM1H181MPD

The UPM1H181MPD is a radial-lead aluminum electrolytic capacitor in the Nichicon UPM series, designed for low impedance and high reliability. It provides 180 µF capacitance at a 50 V rating with a compact φ10 × 20 mm can and 5 mm lead spacing.

Engineered for demanding power applications, this AEC‑Q200 rated, RoHS‑compliant part targets systems that require robust ripple handling, long life at elevated temperature, and through‑hole mounting simplicity.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 50 V rated voltage and ±20% tolerance, suitable for bulk energy storage and decoupling in power rails.
• Low Impedance — Specified impedance of 85 mΩ helps minimize voltage ripple and reduces heating under AC conditions.
• Loss Characteristics — tanδ (DF) 0.10 measured at 20°C and 120 Hz, providing predictable loss performance for filter and smoothing designs.
• High Ripple Current Capability — Low‑frequency ripple current 361.8 mA (120 Hz) and high‑frequency ripple current 670 mA (200 kHz) for reliable operation in switching and pulsating environments.
• Leakage Current — Specified leakage current of 270 µA, supporting stable bias conditions after application of rated voltage.
• Long Endurance — Rated for 5000 hours at +105°C under applied load, enabling extended life in high‑temperature applications.
• Wide Temperature Range — Operating temperature from −55°C to +105°C for use across harsh environments.
• Radial Through‑Hole Package — φ10 × 20 mm can with 5 mm lead spacing (±0.5 mm), radial lead format for straightforward through‑hole assembly; available in bulk/bag packing.
• Automotive Grade — AEC‑Q200 rating included in the product data for designs requiring automotive‑level qualification.
• Compliance — RoHS‑compliant construction for regulatory alignment.

Typical Applications

• Automotive Power Electronics — Bulk filtering and smoothing on DC‑DC converters and power rails where AEC‑Q200 qualification and high temperature endurance are required.
• Power Supply Filtering — Input/output decoupling and bulk energy storage in industrial and embedded switching power supplies benefiting from low impedance and high ripple capability.
• Motor Control Electronics — Ripple suppression and DC link support in motor drives and actuator controllers exposed to elevated operating temperatures.

Unique Advantages

• Stable performance at elevated temperature — 5000‑hour endurance at +105°C provides predictable long‑term behavior in hot environments.
• Effective ripple handling — Combined low impedance and specified ripple current figures reduce voltage fluctuation and thermal stress in switching applications.
• Automotive readiness — AEC‑Q200 rating lets designers specify the part directly into automotive and transportation systems that reference automotive qualification.
• Compact, serviceable form factor — φ10 × 20 mm radial can with standard 5 mm lead spacing simplifies through‑hole placement and replacement in serviceable assemblies.
• Regulatory compliance — RoHS conformity supports deployment in regions with restricted substance requirements.
