The ERJ3RBD393V is a thick film chip resistor manufactured by Panasonic. Chip resistors are passive components used in electronic circuits to provide resistance to current flow. The part number provides information about the resistor's characteristics, specifically the resistance value. In this case, '393' likely represents 39 * 10^3 ohms, which equals 39,000 ohms or 39 kΩ.

Applications

• Current Limiting: Protecting circuit components by restricting the amount of current flowing through them.
• Voltage Division: Creating specific voltage levels by dividing a larger voltage using resistors.
• Pull-up/Pull-down Resistors: Defining a default logic state for digital inputs.
• Feedback Resistors: Setting the gain and stability of amplifier circuits.
• Termination Resistors: Matching impedance in transmission lines to prevent signal reflections.

Features

• Thick Film Construction: Provides good stability and reliability in various operating conditions.
• Surface Mount Device (SMD): Designed for automated assembly on printed circuit boards.
• Resistance Value: 39 kΩ (determined from the '393' marking).
• Compact Size: Allows for high-density circuit designs.
• RoHS Compliant: Meets environmental standards for restricted substances.

Benefits

• Precise Resistance: Provides accurate and consistent resistance values in circuits.
• Easy Assembly: Simplifies manufacturing processes with automated placement.
• Small Footprint: Reduces board space requirements for miniaturized devices.
• Stable Performance: Maintains consistent resistance over a wide range of temperatures and operating conditions.
• Environmentally Friendly: Complies with RoHS standards for reduced environmental impact.

The ERJ3RBD393V resistor is commonly found in a wide range of electronic devices, including consumer electronics, industrial controls, and automotive applications. Designers should always consult the official Panasonic datasheet to confirm critical parameters such as tolerance, power rating, temperature coefficient, and operating voltage to ensure it meets the requirements of the specific application. The 'V' suffix may denote a particular packaging or tolerance specification.

Additional Details: Datasheet parameters to verify include resistance tolerance (e.g., ±1%, ±5%), power dissipation rating (e.g., 1/16W, 1/10W), maximum operating voltage, temperature coefficient of resistance (TCR), and the package size (e.g., 0603, 0805).
