UPS1A682MHD

The UPS1A682MHD is a miniature, low‑impedance aluminum electrolytic capacitor designed for switching power supplies and general‑purpose power filtering. It is a radial‑lead, can‑style capacitor that combines a compact footprint with high ripple handling and a wide operating temperature range.

Key value propositions include low ESR for improved ripple performance, a wide −55°C to 105°C operating range, and long endurance under elevated temperature stress (3000 hours at 105°C), all while meeting RoHS requirements.

Key Features

• Capacitance & Voltage — 6.8 mF rated capacitance with a 10 V rated voltage and ±20% tolerance for bulk energy storage and decoupling in low‑voltage power rails.
• Low Impedance — Specified impedance of 33 mΩ, enabling lower ripple voltage in switching applications where low ESR is required.
• High Ripple Current Capability — Rated ripple current of 2.045 A at 120 Hz and 2.35 A at 10 kHz to support both low‑ and high‑frequency switching environments.
• Wide Temperature & Endurance — Operating temperature from −55°C to 105°C with endurance of 3000 hours at 105°C under rated bias and ripple current.
• Radial Lead, Compact Package — Radial lead mounting with lead spacing of 7.5 mm and package dimensions L: 3.05 × D: 1.6 cm, offering a small footprint for compact power assemblies.
• Leakage and Loss Characteristics (Series‑specified) — Series guidance: leakage current ≤ 0.03CV (µA) after 1 minute at 20°C; tan δ max. for 10 V is 0.20 at 120 Hz (as specified for the UPS series).
• Environmental Compliance — Compliant with the RoHS directive (2011/65/EU, (EU)2015/863).

Typical Applications

• Switching Power Supplies — Bulk smoothing and output decoupling in compact switch‑mode power supplies, leveraging low impedance and high ripple current ratings.
• General‑Purpose Power Filtering — Energy storage and noise suppression in general electronic power rails where a compact radial electrolytic is required.
• Embedded and Industrial Power Modules — Local decoupling in space‑constrained modules that require wide temperature operation and long endurance at elevated temperatures.

Unique Advantages

• Compact footprint with strong energy density — L: 3.05 × D: 1.6 cm package fits tighter board layouts while providing 6.8 mF capacitance for bulk decoupling.
• Low ESR for improved ripple performance — 33 mΩ impedance helps reduce output ripple and heat generation in switching regulators.
• High ripple current handling across frequencies — Rated ripple currents of 2.045 A (120 Hz) and 2.35 A (10 kHz) support both line‑frequency and high‑frequency switching environments.
• Wide temperature range and proven endurance — −55°C to 105°C operation and 3000 hours endurance at 105°C provide robustness for long‑life power designs.
• RoHS compliant — Meets current RoHS directives for regulatory and environmental requirements.
