The RTA02-4D220JTH is a thick film chip resistor array manufactured by Vishay. This array consists of multiple resistor elements in a single package, allowing for efficient use of board space and simplified assembly in various electronic circuits.

Applications:

• Pull-up/pull-down resistor networks: Used for setting logic levels in digital circuits.
• Voltage dividers: Creating specific voltage levels for analog circuits.
• Current limiting in LED circuits: Providing controlled current to LEDs.
• Sense resistors in power supplies: Monitoring current flow in power regulation circuits.
• General-purpose resistor networks: Replacing multiple discrete resistors to save space and assembly time.

Features:

• Resistor array: Contains multiple resistors in a single package.
• Thick film technology: Ensures good stability and reliability.
• Surface mount technology (SMT): Facilitates automated assembly.
• Compact size: Saves valuable board space.
• RoHS compliant: Meets environmental regulations.

Benefits:

• Reduced component count: Simplifies BOM (Bill of Materials) and reduces assembly time.
• Space saving: Smaller footprint compared to using multiple discrete resistors.
• Improved reliability: Fewer solder joints contribute to increased circuit reliability.
• Cost-effective: Can reduce overall system cost compared to using individual resistors.

Technical Specifications:

The RTA02-4D220JTH features four isolated resistors. The resistance value is 22Ω (220 = 22 x 10^0). The 'J' likely indicates a tolerance of ±5%. The package is typically a small outline package (SOP) or similar SMT package. The power rating per resistor and the overall package power rating will depend on the specific series and should be verified in the Vishay datasheet. Refer to the datasheet for details on the operating temperature range, voltage rating, and other critical parameters.
