The WW25XR200JTL is a chip resistor manufactured by Walsin Technology Corporation. Chip resistors, also known as surface mount resistors (SMD resistors), are small, rectangular passive components used to provide a specific amount of electrical resistance in electronic circuits. The 'WW' likely indicates the series of the resistor, '25' relates to the size (e.g., 2512), and 'XR200' defines the resistance value. 'JTL' refers to the tolerance and packaging.

Applications:

• Current Limiting: Used to limit current in LED lighting and other electronic circuits.
• Voltage Dividers: Used in voltage divider circuits to provide a specific voltage output.
• Signal Termination: Used as termination resistors to reduce signal reflections in high-speed circuits.
• Filtering: Used in filter circuits to attenuate unwanted frequencies.
• Pull-up/Pull-down Resistors: Used to define the logic state of a digital input.

Features:

• Small Size: Compact size allows for high-density placement on circuit boards.
• Surface Mount Technology (SMT): Designed for automated assembly using SMT equipment.
• Stable Resistance: Provides a consistent and reliable resistance value over a wide range of operating conditions.
• Low Temperature Coefficient: Minimal resistance change with temperature variations.
• RoHS Compliant: Complies with Restriction of Hazardous Substances (RoHS) directive.

Benefits:

• Space Savings: Small size allows for efficient use of board space.
• Cost-Effective: Provides a low-cost solution for adding resistance to circuits.
• Reliable Performance: Provides stable and consistent performance over time.
• Easy to Assemble: Designed for automated assembly, reducing manufacturing costs.
• Environmentally Friendly: RoHS compliance ensures minimal environmental impact.

Based on similar Walsin resistor naming conventions, 'XR200' likely indicates a resistance value of 20 Ohms. The '25' in the part number usually indicates the size of the resistor package, the 2512. This part is a standard thick film resistor on a ceramic base with terminations to allow it to be soldered to a PCB. Tolerance is indicated by J, commonly 5%. These chip resistors are widely used in modern electronic devices due to their small size, high reliability, and ease of assembly.
