YAGEO RC0402FR-0710KL

Product FAQ

• 1. What are the key electrical and physical specifications of the YAGEO RC0402FR-0710KL resistor?
  The YAGEO RC0402FR-0710KL is a 10kΩ thick-film chip resistor with a tight ±1% tolerance, suited to stable signal-level applications such as voltage dividers and pull-up networks. It uses an 0402 (1005 metric) package, measuring about 1.0mm × 0.5mm with a low profile around 0.35mm high. It is rated 62.5mW (1/16W) and 50V, making it well suited to space-constrained, low-power PCB designs where electrical stability matters.
• 2. Can the YAGEO RC0402FR-0710KL be used in 3.3V and 5V logic and analog circuits?
  Yes. The RC0402FR-0710KL works in 3.3V and 5V digital and analog circuits, including Arduino, ESP32, STM32, and Raspberry Pi systems, where 10kΩ is a standard pull-up/pull-down value for GPIO stabilisation. At 5V it draws only 0.5mA (5V ÷ 10kΩ) and dissipates about 2.5mW, far below its 62.5mW rating. That makes it safe for signal conditioning, ADC biasing, and logic interfacing, but not for power delivery or high-current paths.
• 3. How reliable is the YAGEO RC0402FR-0710KL under long-term thermal and electrical stress?
  The RC0402FR-0710KL operates from −55°C to +155°C, suiting industrial-grade environments, and has a temperature coefficient of ±100ppm/°C for predictable drift. Long-term reliability depends on power derating: operation at higher ambient temperatures calls for reduced load to limit resistance drift. The thick-film construction gives stable general-purpose performance, though continuous operation near maximum power can slightly affect long-term tolerance stability.
• 4. What packaging format and procurement options are available for the YAGEO RC0402FR-0710KL?
  The RC0402FR-0710KL is supplied on standard tape-and-reel for automated SMT assembly, with a full reel of about 10,000 pieces. Cut-tape and small quantities are widely available for prototyping and evaluation. For production, full-reel ordering is preferred to ensure stable pick-and-place feeding and consistent throughput. Availability can vary with distributor stock and regional supply.
• 5. What PCB layout practices should be followed when using a 0402 10kΩ resistor like the YAGEO RC0402FR-0710KL?
  Use an IPC-compliant 0402 land pattern (about 1.0mm × 0.5mm footprint) to ensure good solder wetting and placement accuracy, and standard lead-free reflow profiles with peaks up to 260°C for short durations. A symmetric pad layout helps prevent uneven surface tension during reflow, which can cause tombstoning. In high-impedance circuits, place the resistor close to signal nodes to reduce noise pickup and maintain signal integrity.
