UBT1K220MPD

The UBT1K220MPD is a Nichicon UBT-series aluminum electrolytic capacitor in a radial-leaded can package. It provides 22 µF capacitance at an 80 V rating with a compact φ8 × 11.5 mm package and is designed for high-temperature, high-reliability applications.

Targeted at demanding electronics including automotive and industrial systems, this component delivers a combination of high-voltage capability, elevated operating temperature range, and specified ripple and leakage characteristics for power-rail smoothing and filtering in harsh environments.

Key Features

• Capacitance & Voltage — 22 µF nominal capacitance with an 80 V rated voltage and ±20% tolerance, suitable for energy storage and decoupling on higher-voltage rails.
• High-Temperature Operation — Rated operating temperature range of −40 °C to +125 °C to support elevated-temperature designs.
• Endurance at 125 °C — Life/endurance specified as 2000 hours at +125 °C for the φ8 diameter at 63–100 V (per series endurance data), supporting long-term operation under thermal stress.
• Loss and Leakage — Low dissipation factor (tan δ) of 0.08 measured at 120 Hz, 20 °C, and a measured leakage current of 52.8 µA, enabling predictable loss and self-discharge behavior.
• Ripple Current Capability — Rated ripple current of 100.5 mA at 120 Hz (low frequency) and 150 mA at 100 kHz (high frequency) for effective filtering of both low- and high-frequency components.
• Package and Mounting — Radial lead, can-style package (φ8 × 11.5 mm) with 3.5 mm lead spacing (±0.5 mm), supplied in bulk or bag packing for through-hole assembly processes.
• Qualification & Compliance — AEC-Q200 qualified and RoHS compliant, meeting industry requirements for regulated substance restrictions and automotive-grade qualification status.
• Polarized Device — Polarized electrolytic capacitor for correct orientation in DC power and filtering circuits.

Typical Applications

• Automotive electronic modules — Suited for power-rail smoothing and decoupling in modules where AEC-Q200 qualification and +125 °C capability are required.
• Power-supply filtering — 80 V rating and specified ripple current figures make it suitable for bulk filtering and ripple suppression on higher-voltage DC rails.
• Industrial controls — Compact radial through-hole form factor and high-temperature endurance support legacy board designs and harsh-environment industrial electronics.
• High-temperature electronics — Use in systems that require stable capacitance and controlled loss characteristics up to +125 °C.

Unique Advantages

• High-temperature endurance: Specified 2000 hours at +125 °C for the φ8 size and 63–100 V range, providing predictable long-term performance under thermal stress.
• Automotive-grade qualification: AEC-Q200 qualification supports designs that require recognized automotive-level component qualification.
• Measured electrical stability: Low tan δ (0.08 at 120 Hz, 20 °C) and a defined leakage current (52.8 µA) allow for accurate loss and self-discharge budgeting in designs.
• Dual-frequency ripple handling: Separate ripple current specifications for low (120 Hz) and high (100 kHz) frequencies enable reliable filtering across a broad spectral range.
• Compact through-hole package: φ8 × 11.5 mm can with 3.5 mm lead spacing fits constrained board layouts while supporting conventional radial lead assembly.
• Regulatory compliance: RoHS compliance simplifies regulatory acceptance for commercial and industrial deployments.
