UZS1H3R3MCL1GB

The UZS1H3R3MCL1GB is a Nichicon aluminum electrolytic, chip-type capacitor designed for surface-mount assembly. It delivers 3.3 µF capacitance at a 50 V rating with polarized construction and is specified for automotive applications with AEC-Q200 compliance.

Engineered for board-level power conditioning, the part offers RoHS compliance and endurance defined by 2,000 hours at 85°C. Note: this product is scheduled for discontinuation and is not recommended for new designs.

Key Features

• Electrolytic Chip Construction — Compact chip-type, surface-mount radial can package intended for high-density PCB assembly and automatic mounting.
• Electrical Specs — 3.3 µF rated capacitance at 50 V with ±20% tolerance; polarized configuration for DC power applications.
• Temperature & Endurance — Operating temperature range −40°C to +85°C and endurance specified as 2,000 hours at 85°C under rated voltage.
• Ripple Performance — Rated ripple current values documented for both low and high frequencies (17 mA at 120 Hz; 25.5 mA at 100 kHz) with published frequency coefficients for ripple-current scaling.
• Reliability Characteristics — Leakage current limit and tan δ specifications provided (50 V tan δ max 0.14); stability and impedance ratios given for low-temperature performance.
• Standards & Compliance — AEC-Q200 compliant and RoHS directive compliant (2011/65/EU and EU2015/863).

Typical Applications

• Automotive electronics — Intended for use in vehicle electronic modules where an AEC-Q200–rated electrolytic capacitor is required for board-level power conditioning.
• Power supply decoupling — Suited to smoothing and local energy storage on DC power rails within automotive control units operating within the specified temperature range.
• Filtering in electronic modules — Use where compact surface-mount electrolytic capacitance is needed for ripple reduction and transient absorption in automotive circuits.

Unique Advantages

• AEC-Q200 compliance: Provides the documented qualification relevant to automotive module designs requiring that standard.
• Compact surface-mount format: Chip-type radial can SMD package supports automated placement on high-density PCBs to simplify assembly.
• Documented endurance: 2,000-hour rating at 85°C under load gives a clear reliability expectation for lifetime planning.
• Frequency-aware ripple ratings: Published ripple current values and frequency coefficients enable accurate derating for different operating frequencies.
• RoHS compliant: Meets current RoHS directives for use in regulated manufacturing environments.
