UWR1H4R7MCL1GB

The UWR1H4R7MCL1GB is a surface-mount aluminum electrolytic capacitor offering 4.7 µF capacitance at a 50 V rating in a compact chip/can SMD package. Designed for high-density PC boards and automatic mounting, it delivers predictable electrical characteristics for embedded and automotive electronics.

Key attributes include a small form factor (φ4 × 5.4 mm), AEC-Q200 rating, RoHS compliance, an operating temperature range of −40°C to 85°C, and a rated load life of 2000 hours at 85°C.

Key Features

• Capacitance & Voltage — 4.7 µF capacitance with a rated voltage of 50 V and capacitance tolerance of −20% to 20%.
• Temperature Range & Endurance — Operates from −40°C to 85°C with a rated load life of 2000 hours at 85°C.
• Ripple Current & ESR — Low-frequency ripple current of 18 mA at 120 Hz and high-frequency ripple current of 27 mA at 10 kHz; ESR specified as 18 mΩ at 120 Hz and 27 mΩ at 10 kHz.
• Leakage & Dissipation — Leakage current of 3 µA; tan δ (DF) of 0.14 measured at 20°C, 120 Hz for the 50 V rating.
• Package & Mounting — Radial, can-type SMD package optimized for surface-mount assembly; supplied in embossed carrier taping for automatic placement.
• Quality & Compliance — AEC-Q200 rated and RoHS compliant for regulated markets.

Typical Applications

• Automotive Electronics — Suited for board-level power decoupling and smoothing where AEC-Q200-rated components are required and a 50 V rating is needed.
• High-density SMD Assemblies — Compact φ4 × 5.4 mm can-type form factor allows use on space-constrained PCBs and supports automatic placement with embossed carrier taping.
• Temperature-challenged Environments — Rated for −40°C to 85°C operation and a 2000-hour life at 85°C for designs that require verified endurance under elevated temperature stress.

Unique Advantages

• Compact SMD Can Form — Small diameter and low profile (φ4 × 5.4 mm) reduce board footprint while retaining electrolytic capacitance.
• Automotive-Grade Reliability — AEC-Q200 rating supports use in regulated automotive electronic modules and systems.
• Measured ESR and Ripple Ratings — ESR values (18 mΩ at 120 Hz, 27 mΩ at 10 kHz) and specified ripple currents provide predictable power-decoupling performance across frequency.
• Low Leakage Current — 3 µA leakage current supports low-standby and precision circuits where minimal leakage is important.
• Production-ready Packaging — Embossed carrier taping enables efficient automated placement on high-density PCBs.
• Regulatory Compliance — RoHS compliant for environmentally regulated applications.
