UBW1H221MPD

The UBW1H221MPD is a radial-lead aluminum electrolytic capacitor in Nichicon's UBW series, specified at 220 µF and 50 V. It delivers long-life high-temperature performance with a compact φ10 × 20 mm can and 5 mm lead spacing, targeted for demanding electronics including automotive applications.

Designed for high-temperature endurance and robust ripple handling, this polarized capacitor combines low impedance and defined leakage characteristics to support power filtering and decoupling in space-constrained assemblies operating from −55 °C to +135 °C.

Key Features

• Capacitance & Voltage — 220 µF rated capacitance at 50 V, with capacitance tolerance of −20% to +20% (measured at 120 Hz, 20 °C).
• High‑Temperature Endurance — Rated for operation from −55 °C to +135 °C with a specified endurance of 2000 hours at 135 °C under the stated test conditions.
• Low Loss (tan δ) — Dissipation factor (tan δ) of 0.10 at 50 V, 120 Hz, 20 °C, supporting efficient energy storage with controlled losses.
• Ripple Current Capability — Low-frequency ripple current 623.1 mA at 120 Hz and high-frequency ripple current 930 mA at 10 kHz to support filtering across a range of switching and line frequencies.
• Low Impedance — Rated impedance of 98 mΩ, helping reduce voltage drop and heat generation in power circuits.
• Leakage Current — Specified leakage current of 330 µA, enabling predictable bias behavior in DC applications.
• Package & Mounting — Radial lead, can package with φ10 × 20 mm dimensions and 5 mm lead spacing (lead spacing tolerance ±0.5 mm); available in bulk or bag packing.
• AEC‑Q200 Rated — Series rating identified for automotive-grade qualification, suitable for designs that require that level of component qualification.

Typical Applications

• Automotive electronics — Supports power supply filtering and decoupling in automotive control modules and electronic subsystems where AEC‑Q200 qualification and elevated temperature endurance are required.
• Power rails and smoothing — Used for bulk smoothing and ripple attenuation on DC power rails in compact assemblies.
• Industrial and embedded systems — Applicable where high operating temperature range and long endurance are needed for reliable operation in harsh environments.

Unique Advantages

• High-temperature capability: 2000-hour endurance at 135 °C provides predictable life performance in elevated-temperature applications.
• Automotive-grade qualification: AEC‑Q200 rating aligns the part with automotive design and validation workflows.
• Compact radial can: φ10 × 20 mm footprint and 5 mm lead spacing enable use in space-constrained PCBs while preserving capacitance.
• Robust ripple handling: Specified ripple currents at both low and high frequencies (623.1 mA @ 120 Hz, 930 mA @ 10 kHz) support switching supplies and line-frequency filtering.
• Low impedance and controlled losses: 98 mΩ impedance and tan δ of 0.10 reduce voltage drop and thermal stress under load.
• Predictable leakage: 330 µA leakage current specification aids in power-budgeting and bias stability.
