RC0603FR-07100KL

The YAGEO RC0603FR-07100KL is a 100kΩ thick film chip resistor in the 0603 (1608 metric) surface-mount package, with ±1% resistance tolerance and a 1/10W power rating at 70°C ambient. It measures 1.60mm × 0.80mm with a height of 0.45mm. Its Temperature Coefficient of Resistance is ±100 ppm/°C, and it operates across -55°C to +155°C.

The RC0603FR-07100KL has a maximum working voltage of 75V and a maximum overload voltage of 150V. These limits are independent of the 1/10W power rating: per YAGEO's rated voltage formula, V = √(P×R) or the max working voltage, whichever is lower — so a high-resistance, low-power design can hit the voltage ceiling before it ever approaches the power ceiling. As a general design consideration, this matters most in high-impedance or high-voltage paths (e.g., some industrial or offline supply circuits); for typical 3.3V/5V logic pull-ups, the resistor operates with wide margin.

Yes. The RC0603FR-07100KL is RoHS compliant and halogen-free. It uses lead-free terminations consisting of matte tin over a nickel barrier and has an MSL 1 (Moisture Sensitivity Level 1) rating. The part belongs to YAGEO's RC series of general-purpose thick film chip resistors.

In the part number, RC0603 is the chip size, F is the ±1% tolerance code, R is the paper taping reel packaging type, -07 denotes a 7-inch reel, and 100K is the 100kΩ resistance value (L is a default ordering code with no functional meaning). A 7-inch paper tape reel of RC0603 parts ships in quantities of 5,000 pieces per reel.

YAGEO publishes the recommended PCB footprint and soldering profiles in a separate document, "Chip Resistors Mounting," which should be consulted for the recommended land pattern and reflow profile. The RC0603FR-07100KL uses lead-free matte-tin-over-nickel-barrier terminations and is tested in accordance with J-STD-002 Test B1 (solderability/wetting), J-STD-002 Test D (leaching), and MIL-STD-202 Method 210 Condition B for resistance to soldering heat (260°C ±5°C for 10 ±1 seconds immersion).
