UNI-ROYAL 0603WAF4700T5E

Product FAQ

• 1. What are the fundamental resistance ratings, tolerance limits, and temperature drift parameters of the 0603WAF4700T5E?
  The UNI-ROYAL 0603WAF4700T5E is a thick film surface-mount chip resistor with a nominal resistance of 470 Ω. According to the part number system, the "F" code indicates a ±1% tolerance, while "WA" denotes the 1/10 W power rating. For 0603 resistors with resistance values greater than 10 Ω, the Temperature Coefficient of Resistance (TCR) is ±100 ppm/°C.
• 2. Which continuous power ratings and maximum voltage limits apply to this resistor?
  The 0603WAF4700T5E has a continuous power rating of 0.1 W (1/10 W) at an ambient temperature of 70°C. It has a maximum continuous working voltage of 75 V and a maximum overload voltage of 150 V. When operated above 70°C, the power rating should be derated according to the manufacturer's derating curve.
• 3. What are the physical dimensions and package specifications of the 0603WAF4700T5E?
  The resistor is supplied in a 0603 surface-mount package. Its nominal body dimensions are 1.60 ± 0.10 mm in length, 0.80 ± 0.10 mm in width, and 0.45 ± 0.10 mm in height.
• 4. What operating temperature range applies to the 0603WAF4700T5E?
  The 0603WAF4700T5E is specified for an operating temperature range of −55°C to +155°C. The part number suffix "E" indicates the standard lead-free/environmental protection version defined by the manufacturer.
• 5. What packaging options are provided for automated SMT assembly?
  The "T5E" suffix indicates tape-and-reel packaging, with "T" representing tape and reel, "5" indicating a standard packing quantity of 5,000 pieces, and "E" denoting the lead-free version. For the 0603 package, components are supplied on paper tape with a 178 mm (7-inch) reel containing 5,000 pieces. The datasheet also states that the resistor is suitable for both wave soldering and reflow soldering.
