UPS2A101MHD

The UPS2A101MHD is a miniature, low-impedance aluminum electrolytic capacitor in a radial can package designed for switching power supplies and general-purpose power applications. It pairs a 100 µF capacitance with a 100 V rated voltage to provide compact bulk energy storage and filtering in space-constrained boards.

Built for extended operation across a wide temperature range, this RoHS-compliant capacitor supports high-temperature endurance and measurable ripple-handling capability suitable for switching environments.

Key Features

• Capacitance & Voltage — 100 µF capacitance with a 100 V rated voltage for bulk energy storage and high-voltage filtering tasks.
• Low Impedance — Rated impedance of 180 mΩ, helping reduce ripple voltage in power rails and improve transient response.
• Ripple Current Capability — Specified ripple current of 290 mA at 120 Hz and 580 mA at 10 kHz to support switching-frequency ripple and high-frequency decoupling.
• Wide Temperature Range — Operating temperature from −55 °C to +105 °C for use in demanding thermal environments.
• High-Temperature Endurance — Lifetime specified as 3000 hours at 105 °C under rated bias and ripple conditions, supporting long-term reliability in elevated-temperature designs.
• Package & Mounting — Radial lead, can-style package with 5 mm lead spacing and compact dimensions (L: 2 × D: 1.25 cm) for through-hole mounting.
• Polarized with Standard Tolerance — Polar electrolytic construction with capacitance tolerance of ±20% (–20% to +20%).
• RoHS Compliant — Manufactured to meet RoHS directive requirements.

Typical Applications

• Switching Power Supplies — Bulk smoothing, input/output filtering and decoupling in switch-mode power supply circuits, enabled by the 100 µF/100 V rating and low impedance.
• Power Conversion Modules — Energy storage and ripple suppression for DC–DC converters and power regulator stages, using the specified ripple-current capability at switching frequencies.
• General-Purpose Industrial Electronics — Broad use in industrial and electronic equipment requiring polarized bulk capacitance across −55 °C to +105 °C.

Unique Advantages

• Compact high-voltage solution: 100 µF at 100 V in a miniature radial can provides significant capacitance without a large board footprint.
• Improved ripple performance: Low impedance (180 mΩ) and defined ripple-current ratings at 120 Hz and 10 kHz reduce ripple voltage and thermal stress in switching circuits.
• Wide thermal operating window: −55 °C to +105 °C operation supports designs exposed to varied and extreme ambient conditions.
• Proven high-temperature endurance: 3000 hours at 105 °C under rated conditions for predictable life performance in elevated-temperature applications.
• Simple through-hole integration: Radial lead, can package with 5 mm lead spacing enables reliable mounting for serviceable or ruggedized assemblies.
• Regulatory compliance: RoHS conformity supports environmentally restricted-product requirements.
