RC0402FR-071KL

On LCSC (LCSC# C106235), the RC0402FR-071KL is priced as follows: 100+ pcs: $0.0009 each 1,000+ pcs: $0.0007 each 3,000+ pcs: $0.0006 each 50,000+ pcs: $0.0005 each The minimum order is 100 pieces and the standard full-reel packaging is 10,000 pieces. With over 8.9 million units in stock, this part ships immediately. YAGEO (Manufacturer code: RC0402FR-071KL) is a Tier-1 passive component supplier with broad global availability.

The RC0402FR-071KL is rated at 62.5mW continuous power dissipation. For a 1kΩ resistor at this power limit, the maximum allowable RMS current is approximately 7.9mA and the maximum voltage across the resistor is approximately 7.9V (limited by power, since the voltage rating of 50V is much higher). Thermal derating applies above a threshold temperature (refer to the YAGEO datasheet), and the maximum operating temperature is 155°C. The ±100ppm/°C TCR means at a 100°C temperature rise the resistance shifts by approximately 1%.

The RC0402FR-071KL is a thick film chip resistor in a 0402 package with a resistance of 1kΩ, a tolerance of ±1% (F grade), and a rated power dissipation of 62.5mW. The maximum operating voltage is 50V, the operating temperature range is -55°C to +155°C, and the temperature coefficient of resistance is ±100ppm/°C. The part is RoHS compliant (ECCN: EAR99) and classified under CNHTS 8533211000.

The 0402 chip resistor requires precise paste deposit and pick-and-place alignment. YAGEO's RC-series parts are packaged on standard 10,000-piece tape-and-reel for automated assembly. The minimum order quantity from LCSC is 100 pieces, in multiples of 100. As a RoHS-compliant part, it is compatible with lead-free SAC305 reflow profiles. The 0402 body is susceptible to tombstoning if paste volume or reflow profile is not well controlled; symmetric pad design and balanced paste deposition are recommended.

The 0402 (1.0mm × 0.5mm) footprint is an industry-standard size. Any 0402 thick film chip resistor with a resistance of 1kΩ, tolerance of ±1%, power rating of 62.5mW, voltage rating of 50V, and a temperature coefficient of ±100ppm/°C can serve as a footprint-compatible substitute. Confirm that the alternate part's termination finish and packaging are also compatible with your assembly process before qualifying a replacement.
