UPM1H390MED

The UPM1H390MED is a radial-lead aluminum electrolytic capacitor in Nichicon’s UPM series, specified for 39 µF capacitance at a 50 V rating. It combines a compact φ6.3 × 11 mm can and 2.5 mm lead spacing for through‑hole mounting where a low-impedance, polarized capacitor is required. Designed for robust temperature performance and defined ripple handling, this part is suitable for small power-filtering and general-purpose electronic applications where AEC-Q200 qualification and defined endurance are required.

Key Features

• Capacitance & Voltage — 39 µF nominal capacitance with a rated voltage of 50 V and a capacitance tolerance of −20% to +20%.
• Loss Angle (tan δ) — Specified tanδ 0.10 measured at 20°C, 120 Hz and rated voltage, providing a defined dissipation characteristic for AC conditions.
• Ripple Current Capability — Low-frequency ripple current 76.5 mA at 120 Hz and high-frequency ripple current 150 mA at 200 kHz, suitable for decoupling and smoothing in mixed-frequency circuits.
• Leakage Current — Specified leakage current of 58.5 µA after rated voltage application, allowing predictable standby and bias behavior.
• Temperature & Endurance — Operating range −55°C to +105°C with a rated life of 2000 hours at 105°C for this part number.
• Package & Mounting — Radial lead, polarized aluminum can with dimensions φ6.3 × 11 mm, lead spacing 2.5 mm (±0.5 mm), supplied in bulk or bag packing (no terminal forming).
• AEC‑Q200 Rated — Built to the AEC‑Q200 rating listed in the product specifications.
• RoHS Compliant — Meets RoHS requirements as specified in the product data.

Typical Applications

• Automotive Electronics — Use in on‑board modules and control units where AEC‑Q200 qualification and a compact radial capacitor are required for filtering and supply stabilization.
• Power Supply Filtering — Bulk and decoupling applications benefiting from defined ripple current ratings at both low and high frequencies.
• Sensor and Control Circuits — Small form‑factor power smoothing and biasing in sensor interfaces and control modules operating across −55°C to +105°C.

Unique Advantages

• Compact radial package — φ6.3 × 11 mm can and 2.5 mm lead spacing provide a small footprint for space‑constrained through‑hole designs.
• Defined AC behavior — Specified tanδ and leakage current values allow predictable performance when designing filters and decoupling networks.
• Dual-frequency ripple specification — Rated ripple currents provided for both 120 Hz and 200 kHz support mixed-frequency power environments.
• High-temperature endurance — Rated for operation to 105°C with a specified 2000 hour life at that temperature for design validation.
• Automotive-capable rating — AEC‑Q200 listing supports use in applications requiring supplier qualification to that standard.
• Supply packaging options — Available in bulk (no terminal forming) or bag packing to match assembly and handling preferences.

Why Choose UPM1H390MED?
