UPM1E182MHD6

The UPM1E182MHD6 from Nichicon is a radial‑lead aluminum electrolytic capacitor in the UPM series, offering 1.8 mF capacitance at a 25 V rating. It delivers low impedance and high ripple handling in a compact φ16 × 25 mm can for demanding thermal and electrical environments.

Engineered for automotive and other high‑reliability markets, the device combines a wide operating temperature range (‑55 °C to 105 °C) with a long endurance rating (5,000 hours at 105 °C), providing stable capacitance, controlled dissipation factor, and predictable leakage characteristics.

Key Features

• Electrical Performance — 1.8 mF capacitance at 25 V with ±20% tolerance; measured tanδ of 0.14 (20 °C, 120 Hz) and a rated impedance of 31 mΩ for effective decoupling and energy buffering.
• High Ripple Current Capability — Supports 1.931 A at 120 Hz (low frequency) and 1.97 A at higher frequency, enabling reliable handling of AC ripple and transient currents.
• Reliability & Endurance — Specified for 5,000 hours of load life at 105 °C, with capacitance change within ±20% and leakage current maintained at or below initial specification after endurance testing.
• Temperature Range — Wide operational range from ‑55 °C to 105 °C to accommodate severe ambient and in‑vehicle temperature conditions.
• Mechanical & Packaging — Radial lead construction with φ16 × 25 mm case and 7.5 mm lead spacing; available in bulk (no terminal forming) or bag packing for assembly flexibility.
• Qualification & Compliance — AEC‑Q200 qualified and RoHS compliant, suitable for automotive applications requiring industry‑recognized component qualification.

Typical Applications

• Automotive Electronic Systems — Used where robust filtering, decoupling and energy storage are required under elevated temperatures and sustained ripple loads.
• Power Supply Modules — Provides bulk capacitance and ripple current tolerance for DC‑DC converters and power regulation stages.
• Control and Embedded Electronics — Fits compact radial lead footprints for electronic control units and modules requiring long endurance and low impedance.

Unique Advantages

• Low Impedance, Measurable Performance — 31 mΩ impedance and a specified tanδ (0.14 at 20 °C, 120 Hz) support stable decoupling behavior under load.
• High Ripple Endurance — Rated ripple currents (1.931 A at 120 Hz, 1.97 A at higher frequency) allow the capacitor to sustain continuous AC stress common in switching power applications.
• Long Life at Elevated Temperature — 5,000‑hour endurance at 105 °C offers predictable aging and service life for designs exposed to high thermal stress.
• Automotive Qualification — AEC‑Q200 status and RoHS compliance simplify selection for designs targeting automotive and regulated markets.
• Compact Radial Can — φ16 × 25 mm package with 7.5 mm lead spacing balances high capacitance with a small PCB footprint for space‑constrained layouts.
