UWF1E6R8MCL1GB

The UWF1E6R8MCL1GB is a surface-mount, chip-type aluminum electrolytic capacitor in Nichicon’s UWF series designed for low impedance performance on high-density PC boards. It provides 6.8 µF capacitance at a 25 V rated voltage with polarization and embossed carrier taping for automated placement.

Engineered for elevated-temperature and demanding environments, this capacitor is RoHS compliant and AEC-Q200 rated. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 6.8 µF nominal capacitance with a 25 V rated voltage and ±20% tolerance (measured at 120 Hz, 20 °C).
• Low loss / Low impedance — Tangent of loss angle (tan δ) of 0.14 at 120 Hz, 20 °C and specified impedance of 5 Ω for effective AC performance.
• Ripple and leakage — Rated ripple current of 25 mA at 120 Hz and 50 mA at 10 kHz, with leakage current specified at 3 µA (after 2 minutes at rated voltage, 20 °C).
• Temperature & Endurance — Operating range from −55 °C to +105 °C and endurance of 1000 hours at 105 °C with defined limits on capacitance change, tan δ and leakage.
• Package & Mounting — Chip-type φ4 × 5.4 L can in an SMD radial form factor, surface-mount land recommendation 4.3 × 4.3 mm, and supplied on embossed carrier tape for automatic mounting.
• Reliability & Compliance — AEC-Q200 rated and RoHS compliant; case top marked with black print for part identification.

Typical Applications

• Automotive control modules: Decoupling and smoothing in electronic control units where AEC-Q200 qualification and +105 °C endurance are required.
• Power supply filtering: Bulk and ripple suppression on DC power rails where 25 V rating and low impedance support stable output under ripple stress.
• High-density PCB assemblies: SMD chip can and embossed carrier taping enable automated placement on compact boards for space-constrained designs.

Unique Advantages

• Compact chip can format: φ4 × 5.4 L SMD construction saves PCB area while supporting surface-mount automated assembly.
• Temperature endurance: Rated for operation from −55 °C to +105 °C with 1000 hours endurance at 105 °C for thermal reliability in elevated-temperature applications.
• Low leakage current: 3 µA maximum leakage at 20 °C helps minimize standby losses and maintain circuit stability.
• Defined ripple performance: Specified ripple currents (25 mA at 120 Hz, 50 mA at 10 kHz) and low tan δ support AC smoothing and filtering tasks.
• AEC-Q200 and RoHS compliance: Recognized reliability screening and regulatory compliance for designs requiring controlled material content and automotive-grade screening.

Why Choose UWF1E6R8MCL1GB?

The UWF1E6R8MCL1GB delivers a compact, low-impedance aluminum electrolytic solution for designs that require moderate capacitance at 25 V, controlled leakage, and defined ripple handling across a wide temperature range. Its chip-type SMD package and embossed carrier taping simplify automated assembly on dense PCBs while the AEC-Q200 rating and RoHS compliance address reliability and material requirements.

This part is suited to engineers maintaining or repairing existing systems that specify the UWF series and need a capacitor with documented endurance at +105 °C. Availability planning should account for its discontinued status.
