UWT0G681MNL1GS

The UWT0G681MNL1GS is a chip-type aluminum electrolytic capacitor from Nichicon’s UWT series, specified at 680 µF and 4 V. It is designed for surface mounting on high-density printed circuit boards and for automatic assembly using carrier tape.

This device targets demanding environments with a wide operating temperature range of −55 °C to +105 °C and AEC‑Q200 qualification, providing a compact, automotive-capable option where long-term thermal endurance and reliable SMT assembly are required.

Key Features

• Chip-style SMD package — Radial, can-style SMD construction sized L: 1.0 × D: 0.8 cm with a recommended land pattern of 8.3 × 8.3 mm for high-density PCB layouts.
• Electrical rating — Rated capacitance 680 µF at 4 V with polarization and a tolerance of ±20% (120 Hz, 20 °C).
• Wide temperature range — Specified for operation from −55 °C to +105 °C to support harsh-environment designs.
• Automotive qualification — AEC‑Q200 qualified, suitable for designs requiring automotive-grade component screening and reliability.
• Endurance and reliability — 1000 hours at 105 °C with rated voltage applied; for capacitors ≤16 V (including this 4 V part) capacitance change remains within ±25% after endurance test.
• Leakage current specification — After 2 minutes’ application of rated voltage at 20 °C, leakage current ≤ 0.01CV or 3 µA (whichever is greater).
• Loss and low-temperature behavior — Loss tangent (tan δ) ≤ 0.40 at 4 V (120 Hz, 20 °C); impedance ratios Z(−25 °C)/Z(+20 °C) = 7 and Z(−40 °C)/Z(+20 °C) = 15 for the 4 V rating.
• Assembly-ready — Designed for automatic mounting with carrier tape and compatible with surface-mount production flows; case top marking in black print simplifies identification.
• Soldering robustness — Meets soldering heat resistance test (30 s on 250 °C hot plate) with capacitance change within ±10% and no increase in leakage above initial specified values.
• Ripple handling — Rated ripple currents: 210 mA at 120 Hz and 315 mA at 10 kHz, supporting filtering and decoupling duties in power circuits.

Typical Applications

• Automotive electronics — AEC‑Q200 qualification and wide temperature capability make this part suitable for automotive control modules and electronic assemblies requiring robust capacitive energy storage.
• High-density surface-mount PCBs — Chip-style SMD can and compact footprint are optimized for space-constrained board designs where automated tape-fed placement is used.
• Thermally demanding systems — Specified endurance of 1000 hours at 105 °C supports applications that operate at elevated temperatures or require extended thermal reliability.

Unique Advantages

• Automotive-ready qualification: AEC‑Q200 status delivers the component-level screening expected for vehicle electronic systems.
• Wide operating temperature window: −55 °C to +105 °C rating enables use across extreme temperature environments without derating of the specified operating range.
• Compact, assembly-friendly form factor: Chip-type SMD construction with carrier-tape compatibility reduces PCB area and streamlines high-volume automated placement.
• Proven thermal endurance: 1000-hour endurance at 105 °C under rated voltage with defined limits on capacitance change, tan δ and leakage current.
• Measurable low-temperature performance: Provided impedance ratios quantify behavior at −25 °C and −40 °C for predictable low-temperature system performance.
• Clear electrical limits: Defined leakage current and tan δ specifications (4 V rating) enable straightforward margining in power and filter designs.
