UPM1K120MED

The UPM1K120MED is an aluminum electrolytic capacitor from Nichicon’s UPM series, delivering 120 µF capacitance at an 80 V rating in a compact radial-lead can. Engineered for high-temperature operation and reliability, it supports applications requiring stable bulk capacitance, low loss, and long-term performance in demanding environments.

Its key strengths include a wide operating temperature range of -55 °C to 105 °C, AEC-Q200 qualification, and a low dissipation factor specified for the 80 V rating, making it suitable for embedded power and industrial modules where space and robustness matter.

Key Features

• Capacitance & Voltage — 120 µF nominal capacitance at 80 V rated voltage with ±20% tolerance (measured at 20 °C, 120 Hz).
• High-temperature endurance — Rated for operation up to 105 °C with a specified life of 2000 hours at 105 °C, supporting sustained elevated-temperature use.
• Low loss / tan δ — tanδ (DF) of 0.08 measured at 20 °C and 120 Hz for the 80 V rating, indicating lower dissipation relative to higher-loss parts.
• Ripple performance — Low-frequency ripple current of 24 mA (120 Hz) and high-frequency ripple current of 48 mA (200 kHz) for decoupling and smoothing duties across frequency ranges.
• Leakage current — Specified leakage current of 28.8 µA, supporting predictable standby and bias behavior in circuits.
• Compact radial package — φ6.3 × 11 mm can with 2.5 mm lead spacing (±0.5 mm) in a radial-lead configuration for through-hole assembly and prototyping.
• Automotive-grade qualification — AEC-Q200 rating as specified in the product data, suitable for designs requiring that qualification.
• Packaging options — Supplied in bulk (no terminal forming) or bag packing to match volume assembly or smaller production needs.
• RoHS compliant — Material compliance stated for environmental regulatory requirements.

Typical Applications

• Power supply smoothing — Bulk filtering and energy storage on DC rails where 120 µF at 80 V and low loss are required for stability and ripple reduction.
• Embedded and industrial electronics — Local decoupling and bulk capacitance in control modules and power management circuits operating up to 105 °C.
• Automotive electronic modules — Use in vehicle electronics and modules that require components with AEC-Q200 qualification and endurance at elevated temperatures.

Unique Advantages

• High operating temperature capability: Rated to 105 °C with a defined 2000‑hour endurance, enabling reliable performance in thermally challenging assemblies.
• Predictable electrical behavior: Low tanδ (0.08) and specified leakage current provide consistent loss and leakage characteristics for predictable circuit design.
• Frequency-flexible ripple handling: Specified ripple current values at both low (120 Hz) and high (200 kHz) frequencies support diverse filtering roles across power stages.
• Compact through-hole form factor: φ6.3 × 11 mm radial can with 2.5 mm lead spacing simplifies retrofits and space-constrained PCB layouts that require through-hole components.
• AEC-Q200 qualification: Meets qualification expectations for designs that require the AEC-Q200 standard, aligning with automotive and similarly stringent system requirements.
• Supply flexibility: Bulk and bag packing options accommodate both high-volume assembly and limited-run production workflows.
