UCQ1A681MCL1GS

The UCQ1A681MCL1GS is a chip‑type aluminum electrolytic capacitor designed for surface‑mount assembly and audio applications. It combines a 680 μF capacitance at 10 V with a compact SMD can package and a wide operating temperature range, addressing demanding environments where temperature stability and board‑level assembly compatibility are required.

Targeted at automotive and audio equipment markets, this part is compatible with carrier‑tape automated placement, RoHS compliant, and AEC‑Q200 qualified for reliability in regulated applications.

Key Features

• Capacitance & Voltage — 680 μF rated capacitance at 10 V with ±20% tolerance (120 Hz, 20°C), suitable where high bulk capacitance is needed in a compact footprint.
• Temperature Range — Rated for operation from −55°C to +105°C, supporting wide‑temperature applications and harsh environments.
• Reliability & Qualification — AEC‑Q200 qualified with RoHS compliance (2011/65/EU, (EU)2015/863), and endurance defined as 2000 hours at 105°C.
• Package & Mounting — Chip‑type SMD can (radial can — SMD) designed for surface‑mount assembly and compatible with automatic mounting machines fed by carrier tape.
• Performance Metrics — Leakage current specified as not more than 0.01CV or 3 μA (after 2 minutes at 20°C); tan δ and impedance characteristics measured at 120 Hz (tan δ max. 0.26 at 10 V).
• Ripple Handling — Specified ripple current capability of 400 mA at 120 Hz and 600 mA at 10 kHz for filtering and decoupling in audio and power circuits.
• Assembly Robustness — Meets soldering heat resistance (30 seconds on a 250°C hot plate) and shelf‑life/endurance conditions per datasheet specifications.

Typical Applications

• Automotive audio systems — Bulk and decoupling capacitance for in‑vehicle amplifiers, infotainment audio modules, and other on‑board audio electronics that require stability across wide temperatures.
• Automotive electronic modules — Use in vehicle electronics where AEC‑Q200 qualification and RoHS compliance are required.
• SMD audio equipment — Designed for surface‑mount assembly in audio devices and boards assembled with carrier‑tape automated pick‑and‑place equipment.

Unique Advantages

• Wide operating temperature range: −55°C to +105°C rating supports reliable operation across harsh thermal environments.
• AEC‑Q200 qualified: Qualification suited for automotive electronic designs that require established reliability standards.
• High bulk capacitance in an SMD can: 680 μF at 10 V in a compact chip form factor for space‑constrained boards.
• Assembly‑friendly form factor: Chip‑type SMD can compatible with carrier‑tape automatic mounting simplifies high‑volume manufacturing.
• Defined endurance and solderability: Endurance of 2000 hours at 105°C and resistance to soldering heat per datasheet ensure predictable lifetime behavior in elevated temperature applications.
• Measurable ripple and leakage specs: Specified ripple current values and a quantified leakage current limit allow designers to size and verify power‑filtering performance.
