The best choice for product quality enhancement - MELF Resistor

To correspond with the demand of auto market in recent years, the vehicle grade MELF resistors of Firstohm are all satisfactory to AEC-Q200 standards. The MELF resistors of Firstohm are extensively applied to industrial related products over 30 years. In fact, the specifications of MELF resistors produced by Firstohm have originally exceeded the requirement of specification in auto level. Quality wafer resistor produced under strict quality policies will always be our goal of businesses.

 The advantages of Firstohm MELF RESISTOR: (Vehicle Grade)

  •  MELF resistors production experiences over 30 years, leading quality in the same industry
  •  AEC-Q200 Compliant
  •  Stronger mechanical structure, resistant to seismic vibration and thermal shock.
  •  Excellent in heat dissipation. (Especially suitable for air cooling).
  • Superior surge protection than chip resistors (Surge Proof).
  • Highly stable, suitable for long period usage. (Excellent Stability).
  • Low temperature drift, high precision.
  • Low noise interference

Major application:
Firstohm VEHICLE

 We especially explain the applications aiming at the gate resistor of IGBT driven circuit in latest e-news:

Gate resistor ENChoosing the right gate resistor (Rg) for different IGBT characteristics is extremely important as it affects not only the dynamic performance of the IGBT but also the cost and reliability. The primary role of gate resistors (Rg) in IGBT driver is to eliminate gate-level oscillations, transfer the power losses of the driver and regulate the switching speed of the power switch. The Firstohm, SFP (V) and MM (V), complies with the AEC-Q200 specification and is the best choice for gate resistor in IGBT driver circuits.

 The devil is in the details, your best choice for product quality enhancement - MELF Resistor
