UBT2A221MHD

The UBT2A221MHD is an aluminum electrolytic capacitor in a radial-can package, rated at 220 µF and 100 V. It is designed for high-temperature operation with a specified operating range of −40°C to +125°C and long endurance under load.

Built to serve demanding electronic environments, this AEC‑Q200 qualified, RoHS‑compliant part delivers high ripple-current capability and low leakage for robust power or decoupling applications in automotive and other high-temperature systems.

Key Features

• Capacitance & Voltage — 220 µF nominal capacitance with ±20% tolerance and a 100 V rated voltage for high-voltage smoothing and energy storage.
• High‑Temperature Endurance — Specified lifetime of 5000 hours at +125°C, enabling reliable operation in elevated-temperature environments.
• Ripple Current Performance — Low-frequency ripple current of 1.005 A (120 Hz) and high-frequency ripple current of 1.5 A (100 kHz) to support high-stress power circuits.
• Low Leakage — Leakage current specified at 660 µA, helping maintain circuit stability over long service periods.
• Package & Mounting — Radial lead, can-type package with dimensions φ16 × 25 mm and 7.5 mm lead spacing (±0.5 mm), supplied bulk/bag packed for through-hole assembly.
• Quality & Compliance — AEC‑Q200 qualified and RoHS compliant for applications requiring automotive-grade reliability and restricted-substance compliance.

Typical Applications

• Automotive electronics — Suited for in-vehicle electronic modules that require operation to +125°C and AEC‑Q200 qualification.
• High-temperature power circuits — Designed for systems that demand extended load-life performance at elevated temperatures (5000 h at 125°C).
• Ruggedized electronic assemblies — Use in assemblies where high ripple current capability and low leakage are required to maintain power stability.

Unique Advantages

• High voltage handling: 100 V rating supports higher-voltage rail decoupling and bulk energy storage needs without upsizing the capacitor.
• Extended high‑temperature life: Rated for 5000 hours at +125°C, providing predictable aging and maintenance planning for long‑life applications.
• Robust ripple capability: 1.005 A (120 Hz) and 1.5 A (100 kHz) ripple specifications help absorb AC stress in both low- and high-frequency power stages.
• Compact radial can form factor: φ16 × 25 mm body with 7.5 mm lead spacing for straightforward through-hole mounting in space-constrained designs.
• Automotive-grade qualification: AEC‑Q200 rating signals suitability for demanding environments and streamlined validation for automotive programs.
• Regulatory compliance: RoHS-compliant construction for restricted-substance conformance in regulated markets.
