RC0201FR-07100RL

RC0201FR-07100RL is a surface-mount resistor (chip resistor) in the RC0201FR family, built in a 0201 footprint for very small, low-ohm sensing. The “07100” encodes a nominal resistance of about 0.0710 Ω (71 mΩ), commonly used for current sensing or surge limiting in power-management circuits. The “FR” indicates flame-retardant epoxy; “RL” denotes a reliability/low-inductance variant (exact meaning can vary by manufacturer). Applications include DC-DC converters, battery management, and other power-management circuits where precise low resistance is required. It is RoHS-compliant and designed for reflow soldering. Because low-value resistors have tight tolerances and temperature coefficients, verify the exact tolerance, TC, and power rating from the vendor’s datasheet for your design.

RC0201FR-07100RL is a Yageo 0201, 100 Ω chip resistor. Equivalent parts are any 0201-size 100 Ω chip resistors with the same tolerance and power rating from other manufacturers, e.g.:
- Vishay (0201 100 Ω thick‑film series)
- Stackpole (0201 100 Ω series)
- KOA (0201 100 Ω series)
- Susumu (0201 100 Ω series)
Always verify tolerance, power/derating, temperature coefficient and packaging before substituting.

RC0201FR-07100RL features (typical for this series):
- 0201-size thick-film chip resistor (very small, ~0.6 x 0.3 mm)
- FR series with flame-retardant epoxy coating
- RoHS compliant and lead-free
- End-terminals with Ni barrier for reliable solderability
- Power rating around 0.063 W (60 mW)
- Wide operating temperature range (approximately -55°C to +125°C)
- Tolerances commonly ±0.5% or ±1% (variant dependent)
- Resistance value coded by the part number (07100) – verify exact value from the datasheet
- Suitable for high-density, compact PCB layouts and reflow soldering
Note: for the exact electrical specs (resistance, tolerance, TCR, etc.), consult the manufacturer’s datasheet for RC0201FR-07100RL.
