The FRCS3637 is a precision Bulk Metal® foil current sense resistor in a low-profile 3637 SMD package, designed for high-accuracy current measurement applications in power electronics, automotive systems, and instrumentation. Featuring a 4-terminal Kelvin connection and wrap-around terminations, it offers superior solder-joint reliability and minimizes parasitic inductance and thermal EMF effects. With resistance values from 40 mΩ to 500 mΩ, rated for up to 4 W at 70°C, and boasting tight tolerance (±0.1%), exceptional TCR stability (±10 ppm/°C), and load-life drift under ±0.1%, this component ensures precise, long-term performance in demanding environments. Rated for ESD withstand up to 25 kV, with both leaded and lead-free termination options, it supports robust, reliable operation where accuracy and stability are critical.

Key features of the FRCS3637 Series:

  • Resistance values: 40 mΩ to 500 mΩ
  • Power rating: Up to 4 W at 70°C (derating per datasheet)
  • Tolerance: ± 0.1% — ideal for high-accuracy applications
  • Temperature coefficient (TCR): ± 10 ppm/°C (–55 °C to +125 °C)
  • Load-life stability: ≤ ±0.1% drift at rated power and 70 °C
  • 4-terminal Kelvin configuration: Minimizes lead resistance and improves measurement accuracy
  • Low thermal EMF: Bulk Metal® foil process yields low parasitic thermo-voltage
  • ESD robust: Withstands up to 25 kV, safeguarding against electrostatic discharge
  • Flexible termination: Available in both lead‑free and tin/lead finishes for compliance and performance options
  • Small 3637 SMD format: 9.27 × 9.53 mm footprint with low 0.97 mm profile — space-saving for compact layout

Non-standard technical requirements such as resistance outside of standard range, lower tolerance or TCR are available upon request. Please contact us for further information and availability.

Typical applications of FRCS3637  include:

  • Precision current sensing in battery management systems (BMS), EV chargers, power supplies, and inverters
  • Current measurement for motor control, power amplifiers, and industrial drives
  • Accuracy-critical instrumentation and measurement circuits
  • Aerospace, military & medical electronics demanding high reliability and tight TCR
  • Thermal-sensitive OEM systems requiring low thermal EMF and drift
