UZS1V220MCL1GB

The UZS1V220MCL1GB is a Nichicon UZS-series aluminum electrolytic chip capacitor designed for surface-mount use on high-density PC boards. This polarized, low-profile chip capacitor (4.5 mm height) delivers 22 µF at 35 V with AEC-Q200 qualification and RoHS compliance, making it suited for demanding electronics assemblies that require compact, reliable bulk capacitance.

Engineered for automated surface-mount assembly, the part combines a small footprint with endurance characteristics useful in temperature-stressed environments and automotive electronics applications.

Key Features

• Core Electricals — 22 µF capacitance at a 35 V rated voltage with ±20% tolerance (120 Hz, 20°C); polarized for DC decoupling and bulk storage.
• Package & Mounting — Chip-type aluminum electrolytic in an SMD radial can style sized L: 4.5 × D: 6.3 mm and designed for automatic placement from carrier tape; recommended land size 6.6 × 6.6 mm.
• Temperature & Lifetime — Operating range −40°C to +85°C with endurance specified as 2000 hours at 85°C under rated voltage.
• Ripple Performance — Rated ripple current of 46 mA at 120 Hz and 69 mA at 10 kHz (frequency-dependent coefficients apply per datasheet).
• Electrical Reliability — Leakage current limit after 2 minutes at 20°C is 0.01 CV or 3 µA (whichever is greater); tan δ (max.) for 35 V is 0.14 at 120 Hz, 20°C.
• Compliance & Qualification — RoHS directive compliant and AEC‑Q200 rated (as provided in product data).

Typical Applications

• Automotive Electronics — AEC‑Q200 qualification and compact SMD form factor make it appropriate for automotive control and support circuits on dense PCBs.
• High-density Surface-mount Assemblies — Chip-type package and carrier-tape compatibility enable automatic placement in tightly packed boards where board space is constrained.
• Power Filtering on Compact Boards — Bulk capacitance and specified ripple current ratings support local decoupling and smoothing in compact power sections.

Unique Advantages

• Compact, low-profile SMD form — 4.5 mm height and small L×D footprint allow integration into space-constrained PCB layouts while retaining useful capacitance.
• Automated assembly ready — Designed for carrier-tape feeding and automatic placement to streamline high-volume manufacturing.
• Automotive-grade qualification — AEC‑Q200 rating supports use in designs that require recognized automotive reliability metrics.
• Measured ripple and endurance data — Specified ripple current at both low and high frequencies plus a 2000-hour endurance at 85°C give designers defined performance targets for thermal and electrical stress.
• Regulatory compliance — RoHS compliance simplifies environmental regulatory planning for assemblies.
