The UUX0J681MNL1GS is a surface‑mount aluminum electrolytic capacitor in Nichicon’s UUX series, offered in a compact φ10 × 10L (1 × 1 cm) can‑style SMD package. It delivers 680 µF at a rated voltage of 6.3 V with a wide operating temperature range and endurance targeted for demanding environments.

Designed for automotive applications and other systems where robust temperature performance and long life are required, this chip‑type capacitor combines high capacitance density with defined ripple and leakage specifications to support power supply filtering and energy storage needs on compact PCBs.

Key Features

• Capacitance & Voltage — 680 µF rated capacitance with a 6.3 V rating and tolerance of −20% to +20% at 120 Hz, 20°C.
• Temperature Range & Endurance — Rated for −55°C to 105°C with an endurance of 2000 hours at 105°C (voltage applied), supporting wide temperature operation.
• Ripple Performance — Specified ripple capability of 408 mA at 120 Hz (low frequency) and 530.4 mA at 10 kHz (high frequency) to handle AC stress on power rails.
• Leakage & Dissipation — Measured leakage current of 128.52 µA and tanδ (DF) of 0.22 at 120 Hz, 20°C for predictable loss characteristics.
• Package & Mounting — Compact φ10 × 10L can packaged for surface‑mount placement; supplied in embossed carrier taping for automated assembly. Surface mount land size: 1.03 × 1.03 cm.
• Qualification — Built to AEC‑Q200 ratings, indicating suitability for automotive use as specified in the product data.

Typical Applications

• Automotive power modules — Bulk capacitance and ripple handling for low‑voltage DC power rails in automotive electronic control modules.
• On‑board power filtering — Smoothing and decoupling in compact power supply sections where high capacitance density is required.
• Embedded systems — Energy storage and transient suppression in space‑constrained SMD designs operating over a wide temperature range.

Unique Advantages

• High capacitance in a compact SMD can — 680 µF in a φ10 × 10L package provides significant bulk capacitance for small PCB footprints.
• Wide temperature capability — −55°C to 105°C rating supports use across extreme ambient conditions specified in the product data.
• Automotive qualification — AEC‑Q200 rating included in the specifications for designs that require automotive‑grade components.
• Defined ripple and leakage specs — Published ripple current and leakage figures (408 mA @120 Hz, 530.4 mA @10 kHz, 128.52 µA leakage) simplify thermal and lifetime planning.
• Assembly‑friendly packaging — Embossed carrier taping supports automated surface‑mount placement and streamlined production.
• Long endurance at elevated temperature — 2000 hours at 105°C with rated voltage applied provides a predictable lifecycle metric for reliability planning.
