UCA2E680MHD

The UCA2E680MHD is a miniature radial‑lead aluminum electrolytic capacitor designed for applications requiring high ripple current handling and extended life at elevated temperatures. It is a polarized, radial can package rated at 250 V with 68 µF capacitance, aimed at power supply filtering and ballast circuits where compact size and durability are needed.

Key value propositions include a high rated ripple current (up to 1 A at 100 kHz), a long endurance rating of 12,000 hours at 105 °C, and a compact 16 mm diameter by 25 mm length case. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Electrical Performance — 68 µF capacitance at a rated voltage of 250 V with ±20% tolerance, making it suitable for mid‑voltage DC filtering and energy storage tasks.
• High Ripple Capacity — Rated ripple current of 500 mA at 120 Hz and 1 A at 100 kHz, with frequency coefficients defined for broader operating bands to support power supply and ballast ripple demands.
• Long Life Reliability — Endurance specified at 12,000 hours at 105 °C under rated DC bias plus rated ripple current, with defined limits for capacitance change, tan δ, and leakage current after the endurance test.
• Thermal Range — Operating temperature range from −25 °C to +105 °C, suitable for many industrial and commercial electronic environments.
• Compact Radial Can Package — 16 mm diameter × 25 mm length with 7.5 mm lead spacing and radial leads (lead diameter 0.8 mm), enabling easy through‑hole mounting in space‑constrained boards.
• Loss and Leakage Characteristics — Tangent of loss angle (tan δ) specified at 0.15 (max) for 250 V rating; leakage current defined as ≤ 0.04CV + 100 µA after 1 minute at 20 °C.
• RoHS Compliant — Manufactured in compliance with the RoHS directive.

Typical Applications

• Power Supplies — Bulk and smoothing capacitor for DC power rails where elevated ripple handling and long operational life are needed.
• Ballast Circuits — Filtering and energy buffering in ballast designs that require compact, high‑ripple capacitors.
• General‑Purpose Industrial Electronics — Through‑hole radial mounting for control and power modules that benefit from a compact 16 mm × 25 mm can and proven endurance at 105 °C.

Unique Advantages

• High ripple endurance: Rated ripple current up to 1 A at 100 kHz supports demanding filtering tasks and reduces the need for parallel components.
• Extended high‑temperature life: 12,000 hours at 105 °C provides predictable long‑term performance in thermally stressed environments.
• Compact footprint: 16 mm diameter and 25 mm length deliver a small can size for space‑limited PCB layouts while retaining robust capacitance and voltage rating.
• Clear electrical limits: Specified tan δ and leakage current figures allow straightforward margin calculations for reliability and ripple‑loss budgeting.
• Radial through‑hole simplicity: Standard 7.5 mm lead spacing and radial lead format make assembly and prototyping straightforward for legacy and industrial boards.
• RoHS compliance: Conforms to environmental requirements for modern electronics manufacturing.
