UWF1V3R3MCL1GB

The UWF1V3R3MCL1GB is a chip-type aluminum electrolytic capacitor from Nichicon's UWF series designed for surface-mount, high-density PC board assembly. It delivers a nominal 3.3 µF capacitance at a 35 V rating, with low impedance characteristics and an operating temperature range from -55°C to +105°C.

This part is AEC-Q200 compliant and suited for automotive and other demanding environments that require temperature durability and compact SMD packaging. Note: this product is scheduled to be discontinued and is not recommended for new designs.

Key Features

• Capacitance & Voltage — 3.3 µF capacitance rated at 35 V for decoupling and bulk energy storage in compact circuits.
• Temperature Range — Rated for -55°C to +105°C operation, supporting designs exposed to a wide thermal span.
• Low Impedance — Specified impedance of 5 Ω to support stable performance in power-conditioning and filtering applications.
• Reliability & Qualification — AEC-Q200 compliant, providing a recognized qualification for automotive-focused designs.
• Mounting & Package — Chip-type, surface-mount radial can (SMD) package sized L: 5.4 × D: 4 mm with recommended land 4.3 × 4.3 mm for automated placement.
• Endurance — Rated lifetime of 1000 hours at 105°C, with endurance characteristics tested per series specifications.
• Ripple Current — Low-frequency ripple: 25 mA at 120 Hz; high-frequency ripple: 50 mA at 10 kHz for AC stress handling.
• Regulatory — RoHS compliant (2011/65/EU, (EU)2015/863).

Typical Applications

• Automotive Electronics — Energy buffering and decoupling in vehicle control modules and sensor interfaces where AEC-Q200 qualification is required.
• Power Supply Filtering — Local bulk capacitance and smoothing in compact DC–DC converters and regulator output stages.
• Embedded Systems — Board-level decoupling in high-density SMD layouts for industrial and instrumentation electronics.

Unique Advantages

• Compact SMD Form Factor: Small L: 5.4 × D: 4 mm package and 4.3 × 4.3 mm land size enable high-density PCB layouts and automated assembly.
• Automotive-Grade Qualification: AEC-Q200 compliance supports integration into automotive subsystems and designs targeting regulated environments.
• Wide Temperature Tolerance: Operation from -55°C to +105°C helps maintain capacitance stability across harsh thermal conditions.
• Tested Endurance: 1000 hours at 105°C rating provides defined lifetime expectations under elevated-temperature stress.
• RoHS Compliance: Meets environmental restrictions for lead- and mercury-free manufacturing requirements.

Why Choose UWF1V3R3MCL1GB?

The UWF1V3R3MCL1GB combines a compact chip-type SMD package with AEC-Q200 qualification and a broad operating temperature range, making it suitable for designs that require reliable decoupling and bulk capacitance in space-constrained assemblies. Its defined ripple current ratings and 1000-hour endurance at 105°C give clear, verifiable parameters for thermal and electrical planning.

This part is best suited for engineering teams working on maintenance or replacement within established platforms that already specify the UWF series. Given its discontinuation status, evaluate this capacitor for legacy support and service inventory rather than for new product introductions.
