UPM2A181MHD

The UPM2A181MHD is a Nichicon UPM-series aluminum electrolytic capacitor specified at 180 µF and 100 V in a radial-lead can package. It is designed for high-voltage, high-temperature applications requiring long endurance and low impedance in a compact through-hole form factor.

Targeted use includes automotive and power-electronics designs where AEC‑Q200 qualification, extended operating temperature range, and multi-kilohour life at elevated temperature are required.

Key Features

• Capacitance & Voltage — 180 µF nominal capacitance with a 100 V rated working voltage and ±20% tolerance.
• Low Impedance — Specified impedance of 98 mΩ to support low-loss energy storage and decoupling.
• Loss Factor (tan δ) — tanδ of 0.08 measured at 20°C, 120 Hz, 100 V for predictable dissipation characteristics.
• Ripple Current Capability — 486 mA at 120 Hz (low frequency) and 900 mA at 200 kHz (high frequency) for handling AC ripple across a range of switching conditions.
• Leakage Current — Specified leakage current of 540 µA at rated conditions.
• High-Temperature Endurance — Rated life of 5000 hours at 105°C when operated within specified conditions.
• Robust Temperature Range — Operation from −55°C to +105°C to accommodate broad environmental conditions.
• Package & Mounting — Radial lead, can-style package (φ12.5 × 30.5 mm length) with 5 mm lead spacing (±0.5 mm); available in bulk or bag packing.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant for regulated and safety-conscious designs.

Typical Applications

• Automotive Electronics — Use in automotive systems where AEC‑Q200 qualification, 100 V rating, and −55°C to +105°C operation are required.
• Power Supply Filtering — Bulk energy storage and smoothing on DC rails that require 180 µF of capacitance at up to 100 V.
• High-Temperature Systems — Applications needing long life at elevated temperatures, supported by the 5000 h endurance at 105°C.

Unique Advantages

• High-voltage capability: 100 V rating enables use on higher-voltage DC buses without stacking components.
• Long elevated-temperature life: 5000 hours at 105°C provides predictable longevity in demanding thermal environments.
• Robust ripple handling: Dual-frequency ripple current specs (486 mA at 120 Hz, 900 mA at 200 kHz) support both linear and switching power applications.
• Low impedance: 98 mΩ impedance reduces losses and improves transient response on power rails.
• AEC‑Q200 qualification: Design confidence for regulated automotive and related applications requiring industry qualification.
• Through‑hole convenience: Radial-lead can package with standard 5 mm lead spacing simplifies prototyping and wave/manual assembly.
