UPM1K390MPD

The UPM1K390MPD is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering a 39 µF capacitance at an 80 V rating. It is a polarized, can-style radial component designed for high-reliability power applications where moderate capacitance, elevated voltage rating and compact size are required.

Designed for applications that demand stable performance across a wide temperature range, the UPM1K390MPD pairs an operating range of -55 °C to 105 °C with AEC-Q200 qualification and RoHS compliance for use in demanding environments.

Key Features

• Electrical Performance — 39 µF capacitance at 80 V rated voltage with a capacitance tolerance of ±20% (120 Hz, 20 °C).
• Low Loss and Impedance — Tangent of loss angle (tanδ) specified at 0.08 (20 °C, 120 Hz) and measured impedance of 460 mΩ, supporting efficient AC performance.
• Ripple Current Capability — Low-frequency ripple current of 86.7 mA at 120 Hz and high-frequency ripple current of 170 mA at 200 kHz for decoupling and smoothing duties.
• Leakage Current — Specified leakage current of 93.6 µA for predictable DC behavior after voltage application.
• Reliability & Endurance — Endurance rated to 3000 hours at +105 °C for this case size, reflecting the UPM series’ low-impedance, high-reliability design.
• Package & Mechanical — Compact φ8 × 15 mm can with radial leads, 3.5 mm lead spacing (±0.5 mm tolerance) and bulk/bag packing options for production handling.
• Compliance — AEC‑Q200 qualified and RoHS compliant, meeting industry requirements for quality and environmental standards.

Typical Applications

• Automotive Electronics — Bulk decoupling and local energy storage in control modules where AEC‑Q200 qualification and a wide temperature range (-55 °C to 105 °C) are required.
• Power Supply Filtering — Rail stabilization and smoothing in DC/DC converters and intermediate bus circuits benefiting from 80 V rating and low impedance.
• Motor Control and Drive Circuits — Energy buffering and ripple attenuation in motor drive electronics that require durable components with specified ripple current capability.
• Industrial Control — Filtering and transient absorption in industrial electronics operating across wide temperatures and needing long endurance at elevated temperature.

Unique Advantages

• Voltage Headroom for Higher-Duty Circuits: 80 V rated voltage enables use in higher-voltage rails without stepping up component count.
• Compact, Radial Can Format: φ8 × 15 mm package with 3.5 mm lead spacing gives a small footprint for dense PCB layouts while keeping through-hole mounting simplicity.
• Predictable AC Behavior: Specified tanδ (0.08) and measured impedance (460 mΩ) provide designers with explicit loss and ESR characteristics for accurate power-loop modelling.
• Proven Endurance at Elevated Temperature: 3000 hours at 105 °C for this case size supports long-term performance in thermally demanding applications.
• Automotive-Grade Qualification: AEC‑Q200 rating supports selection for automotive and similarly demanding applications that require qualified components.
• RoHS Compliant: Meets environmental requirements for modern electronics production and supply chains.
