UPM1H220MED

The UPM1H220MED is a radial-lead aluminum electrolytic capacitor from Nichicon’s UPM series, offering 22 µF capacitance at a 50 V rating with polarized construction. It’s designed for applications requiring compact power decoupling and smoothing with low loss and controlled leakage.

Key attributes include a wide operating temperature range (−55°C to 105°C), a low dissipation factor (tanδ = 0.1), and AEC-Q200 qualification, making it suitable for demanding electronic designs where reliability and thermal endurance are important.

Key Features

• Capacitance & Tolerance — 22 µF nominal capacitance with ±20% tolerance (measured at 120 Hz, 20°C), suitable for bulk decoupling and smoothing functions.
• Rated Voltage — 50 V rating for mid‑voltage power rails and intermediate bus applications.
• Low Loss — Tangent of loss angle (tanδ) of 0.1 reduces heating and improves AC performance under ripple conditions.
• Controlled Leakage — Specified leakage current of 33 µA supports predictable bias behavior in power circuits.
• Ripple Current Capability — Specified ripple current: 50 mA at 105 Hz, 345 mA at 120 Hz, and 100 mA at 200 kHz, enabling use in both low- and higher-frequency ripple environments.
• Reliability & Lifetime — Rated for 2000 hours at 105°C, providing defined endurance for thermal stress conditions.
• Mechanical & Mounting — Compact radial can package, φ6.3 × 11 mm body (1.1 cm height by 0.63 cm diameter) with 2.5 mm lead spacing for through‑hole assemblies and tight board layouts.
• Environment & Qualification — RoHS compliant and AEC‑Q200 rated, addressing regulatory and automotive-grade qualification requirements.

Typical Applications

• Automotive Electronics — Power filtering and decoupling in control modules, sensors, and lighting where AEC‑Q200 qualification and temperature range are required.
• DC Power Supplies — Bulk smoothing and output decoupling on intermediate rails at up to 50 V.
• Embedded Systems — Local energy storage and transient suppression for microcontroller power domains and peripheral power rails.

Unique Advantages

• Compact footprint: Small φ6.3 × 11 mm can and 2.5 mm lead spacing enable tight placements on densely populated PCBs.
• Defined thermal endurance: 2000 hours at 105°C gives designers a clear reliability target for high‑temperature applications.
• Predictable electrical performance: Low tanδ and specified leakage current provide stable behavior under bias and ripple conditions.
• Frequency versatility: Ripple current ratings at multiple frequencies (105 Hz, 120 Hz, 200 kHz) make the part suitable across both line-frequency and higher-frequency converter stages.
• Industry qualification: AEC‑Q200 rating and RoHS compliance support use in regulated and automotive environments.
